The PPA5xx/15xx family of power analysers covers 1 to 3 phase applications in both low current and high current models. Each phase input has wide ranging voltage and current channels which are fully isolated from each other and from ground. The voltage input has a built in high voltage attenuator or may be used with an external attenuator. The current input has a built in current shunt or may be used with an external shunt. The voltage and current inputs are simultaneously sampled and the data is analysed in real time by a high speed DSP (digital signal processor). A separate CPU (central processing unit) takes the DSP results for display and communications. At the heart of the system is an FPGA (field programmable gate array) that interfaces the various elements. This powerful, versatile structure allows the measurement of a wide range of power related parameters including: W, VA, VAr, power factor, phase true rms, fundamental harmonics, TIF integrated values (W hours etc.) impedance inrush current, voltage surge oscilloscope (PPA15xx only) KinetiQ is particularly easy to use, with a large clear colour display and single menu levels for all main parameters. Even difficult applications such as lighting ballasts can be 1-1 easily addressed with the special modes application in the firmware of the instrument. The whole operation of the instrument may be controlled remotely via a serial interface (RS232/USB), or optionally a LAN interface. The voltage and current channels are identical except for the voltage attenuator and current shunt at the very front end. Each channel consists of a selection switch for external or internal attenuator/shunt followed by a high impedance buffer, then a series of gain stages leading to an A/D converter. Selection of the input gain and the sampling of the A/D converter are under the control of the DSP. There is an autozero switch at the front end for dc accuracy. The analogue circuitry is optimised for high linearity over a wide dynamic range and high frequency performance. The PPA5xx/15xx includes an internal - x10 mode which adds a x10 gain stage to the analogue amplifier chain. This allows measurement of even smaller signals with the caveat that the bandwidth is reduced to c. 100 khz. Both input channels are fully isolated with very good CMRR and noise rejection. The current shunt is of a proprietary design which gives very wide bandwidth with minimum phase shift. The voltage attenuator is of a proprietary design which has a wide bandwidth response matched to that of the current shunt. Both the voltage and current channels are calibrated digitally so there are no physical adjustments to be made. 1-2 2 Getting started KinetiQ is supplied ready to use it comes complete with an appropriate power lead and a set of test leads. It is supplied calibrated and does not require anything to be done by the user before it can be put into service. 2.1 Unpacking and power-up Inside the carton there should be the following items: one KinetiQ unit one appropriate mains lead one red, one yellow and two black 4mm leads per phase one red, one yellow and two black crocodile clips per phase one null modem cable one USB cable Communications manual User manual (this manual) Before connecting the test leads to an active circuit first connect the mains cord from a properly grounded supply outlet to the inlet on the rear panel of the KinetiQ. KinetiQ has a universal mains input and accepts any supply voltage from Vrms at 50 or 60Hz. Note: If the power is cycled off-on within a 10 second time period, the message Turn power off for 10 seconds appears. A 10 second power off window allows all micro controllers to fully reboot and prevents any errors during the power on sequence. Switch on the KinetiQ. The display should illuminate with the model name and the firmware version for a few seconds while it performs start-up checks. It should then 2-1 default to the power measurement display. Note that the switch-on message can be personalised see the User Data section under System Options. The screen is a 4.3 (110mm) LCD colour display. There are no manual adjustments as the display should be clear and visible in all lighting applications. Allow 30 minutes warm up time before commencing any tests to ensure accurate readings. The voltage and current leads may now be connected to a circuit under test. The high common mode rejection ratio (CMRR) of the instrument allows the current channel to be connected in the live path (high side shunt) instead of the neutral path (low side). The test leads supplied meet the safety requirements of BSEN to an operating voltage of up to 1000V rms cat II or 600V rms cat III. The Quick Start guide, Section 3 below, gives an introduction to the operating modes of the KinetiQ, and the selection of options and parameters. The Quick Start guide may be followed with no inputs connected to the instrument. In the event of any problem with this procedure, please contact customer services at Newtons4th Ltd. or your local authorised representative; contact addresses and telephone numbers are given in the appendix at the back of this manual. 2-2 3 Quick Start guide 3.1 Operating Mode Keys Operating Mode selection (Power-on default is Power Analyzer diagram below shows single-phase display. Note that with no inputs connected, display will be showing noise levels only.) Press the POWER, HARM, RMS, or SCOPE (PPA15xx only) keys to access the operating modes directly, (other modes are available via the MODE menu see below). 3-1 Select Menu Options Press the Operating Mode key, e.g. POWER, a second time, or press the MODE key, to access mode-specific options (diagram below shows Power Analyzer options). Use UP and DOWN keys to highlight option, and ENTER to confirm (see para. 3.2 Menu Control Keys). Parameter values within the selected option may be adjusted using the L or R keys or by entering a numeric value directly, as indicated. Press ENTER to confirm. With operating mode highlighted, use the L and R keys to cycle through operating modes and to access Phase Meter mode. Use ENTER or HOME to return to readout display. For text entry see 3.7 Data Entry Guide. 3-2 3.2 Menu Control Keys ENTER/NEXT confirms your selection or parameter value/data entry. HOME/ESC returns to the original entry or to your previous action. DELETE/BACK removes a previous selection or value, or returns to your previous action. ARROW KEYS (UP, DOWN, L, R) move around menu options; make incremental/decremental changes etc. They are also used to position cursors in Scope mode. 3-3 3.3 Display Control Keys PPA15xx ZOOM - up to 4 displayed values may be emphasized. a.

DATALOG only available for Power Analyzer and True RMS Voltmeter modes; sampling interval and storage location. Datalog is disabled by default. (See also TABLE, GRAPH in 3.3 Display Control Keys.) APP application-specific measurements, e.g. inrush current. MATHS a choice of three formulae functions of up to four measurements. ALARM audible/visual indication of thresholds crossed set by ZOOM values (see 3.3 Display Control Keys). Default is Alarm disabled. REMOTE configure external comms. AUX Phase-Controlled Inrush Switch control. SYS configure general system features. MODE see 3.1 Operating Mode Keys. PROG save, recall or delete Mode, Display and Setup configurations for user-defined applications. Recall data saved in DATALOG (see DATALOG key above). For numeric entry see 3.7 Data Entry Guide. 3-7 3.5 Control Keys START & STOP datalog function (when enabled) or integration (Integ mode). Either key also triggers singleshot in Scope mode. Use ZERO key for: a. Zero compensation of input amplifier chain. b. Reset integrator to zero (Integ mode). TRIGGER (or START) returns display to Real Time from Hold. It also arms single-shot triggering in Scope mode. 3-8 3.6 Scope Mode (PPA15xx only) Selecting Scope mode from the operating mode keys, or by cycling through the operating modes in any of the operating mode select options, displays voltage and current waveforms as a conventional oscilloscope diagram below shows the default display with no inputs connected. The following diagram shows the options available in Scope mode: 3-9 A typical display of voltage and current waveforms for a switched mode power supply is shown below: When operating in Scope mode, the L and R control keys operate in one of two ways: A. With the cursor option off (default), the L and R control keys change the timebase. 3-10 B. With the cursor option on the L and R control keys change the cursor position and the UP and DOWN keys toggle between cursor 1 control and cursor 2 control. When cursors are enabled, the scope screen will display the following parameters; Vrms, Vpk, Watts, pf, Arms, Apk 3.7 Data Entry Guide Text Entry Use MODE key to select text entry. Enter text via the 4 function keys in the upper right of the panel. Each function key jumps to a different letter of the alphabet: (POWER) A, (HARM) I, (RMS) O, (SCOPE) space Choose other characters by stepping forward or backward using the UP and DOWN keys. Select upper/lower case with the ZOOM key. (Values may be overwritten or edited by use of the L, R and DELETE keys) Alternatively text entry can be made via the numerical keypad resembling a telephone keypad, where key 1 is symbols, key 2 ABC, key 3 DEF etc. Numeric Entry Use MODE/numeric keys for number, decimal point, or +/ to enter parameter value. The 4 function keys in the upper right of the panel may be used as quick multipliers, where 3-11 POWER is 10 6 (M), HARM is 10 3 (k), RMS is 10-3 (m), and SCOPE is 10-6 (µ). Press ENTER (menu control keys) to set value. Press HOME (menu control keys) to abort data entry, restore original. (Values may be overwritten, or edited by use of the R, L and DELETE keys) 3-12 4 Using the menus KinetiQ is a very versatile instrument with many configurable parameters. These parameters are accessed from the front panel via a number of menus. Each of the main menus may be accessed directly from a specific key. ACQU data acquisition parameters such as speed and filtering COUPLING select ac/dc coupling RANGE select input ranges, and scaling DATALOG specify datalog parameters APP Application specific functions MATHS User defined computations ALARM control of audible alarm REMOTE communications options (RS232 etc) AUX control of auxiliary devices connected to the rear EXTENSION and AUX ports SYSTEM general system options such as phase convention, keyboard beep etc. MODE function control PROG recall/store/ delete of programs and datalog Each menu starts with the currently set parameters visible but no cursor. In this condition, pressing the menu key again or the HOME key aborts the menu operation and reverts to normal operation. To select any parameter, press the UP or DOWN key and a flashing box will move around the menu selecting each parameter. In this condition the keys take on their secondary function such as numbers 0-9 etc. Pressing the HOME key reverts to the opening state where the parameters are displayed but the cursor is hidden. 4-1 Pressing the HOME key again exits the menu sequence and reverts to normal operation. To abort the menu sequence, press the HOME key twice. There are three types of data entry: selection from a list numeric text 4-2 4.1 Selection from a list This data type is used where there are only specific options available such as the smoothing may be normal, slow, or none, the graph drawing algorithm may use dots or lines. When the flashing cursor is highlighting the parameter, the R key steps forward through the list, and the L key steps backwards through the list. The number keys 0-9 step directly to that point in the list, which provides a quick way to jump through long lists. There is no need to press the ENTER key with this data type For example, if the smoothing selection list comprises the options: normal (item 0) slow (item 1) none (item 2) and the presently selected option is normal, there are 3 ways to select none: press R twice press L once press number 2 4-3 4.2 Numeric data entry Parameters such as external shunt impedance and scale factor are entered as real numbers; shunt impedance is an example of an unsigned parameter, scale factor is an example of a signed parameter. Real numbers are entered using the number keys, multiplier keys, decimal point key, or +/- key (if signed value is permitted). When the character string has been entered, pressing the ENTER key sets the parameter to the new value. Until the ENTER key is pressed, pressing the HOME key aborts the data entry and restores the original number. If a data value is entered that is beyond the valid limits for that parameter then a warning is issued and the parameter set as close to the requested value as possible. For example, the minimum user defined measurement window 10ms; if a value of 5ms is entered, a warning will be given and the amplitude set to the maximum of 10ms. When the parameter is first selected
