1.1 Important functionsThis SHP-98ST three phase portable standard meter measurement possesses complete testing,wiring check ,management, and software upgrade functions.Please read this user manual carefully before operating .
The calibrator is a three phase portable standard meter with 3 components for electronic energy measurement . Connect L2 voltage clips to voltage N terminal of the electronic meter when 3P3W electronic energy meter is measured . There are two multiplier units, so the active power , reactive power, and their errors can be calculated simultaniously. Meanwhile, two electronic energy low frequency impulses also can be received at the same time.
32-bit high speed digital signal processor : The calibrator is a powerful calibrator, based on 32-bit high speed 150 MHz DSP from TI Company and high performance 16-bit AD with 6 channels from AD Company. The digital multiplier units with multiple functions and wide range of measurement was successfully developed by means of floating point computations .Therefore, a calculating accuracy can be guaranteed.
To measure active and reactive power ,or calculate errors for electronic energy meters simultaniously: Increasing the working efficiency up to two times comparing with the traditional calibrator.
wiring emulation function:The various wiring methods can be emulated in office by the calibrator without connecting voltage or current signals.This function will be used as a wrong wiring check tool to improve wrong wiring check capability of the field operator.
error self checking for 5A clamp :The 5A current signal will be generated and output to 5A clamp by calibrator in order to measure errors of the 5A clamp , avoiding the accuracy change problem after long time use , enabling the operator to have a clear picture of the closed status for the month of 5A clamp ,waking up the operator to clear the 5A clamp mouth in time.
automatic code reading for electronic energy meter (optional):Supporting code scanner and code reading for electronic energy meter automatically.
ultra-wide range scope for current measurement :Up to 500 times scope for current measurement , metrology accuracy will be gauranteed.Up to 10000 times scope for current measurement and display are possiple.The minimum starting current is 1mA .Wiring identification is possible for empty load in the field of high voltage and current metrology box situation.
accumulative function for electronic energy :Capable of calibrating electronic meter without electronic energy impulse output.

1.2 Other functionsLarge colour screen display with 7 inches industrial TFT, fine clearance ,high resolutions , abundant information ,all relevant data measured will be displayed by one screen .User can view all data measured at glance without page flipping.
The active and reactive electronic energy errors, voltage, current, active and reactive power, phase ,frequency ,and power factor can be measured simultaniously, while vector figure and wiring check results displayed.
Without any adjustable resistor in the calibrator ,all errors will be modified by software.
All input keys are arranged in a style of computer keyboard .
The ratio of the low voltage CT can be measured directly with 5A,100A,500A,1000A clamp .All troubles, such as disconnected cable of the secondary circuit of CT , badly connected wiring , short circuit of turns within CT, and mismatched nameplate data will be discovered .
U1,U2,U3 voltage, and harmonic from 2 to 21 times of current waves can be measured in the real time mode to let the operator have a clear picture of the quality of electronic power supply.
The wave form of L1,L2,L3 voltage or current can be measured and displayed .
Wide range operational voltage from 80V to 480V
The 0.1% measuring accuracy for all measured points as well as 1A rated secondary circuit of CT will be gauranteed while overloading for 100% within wide current scope of 0.02A-5A.
calibrator data measured for 5000 times can be saved .
Convenient data copy with USB interface capable of connecting to flashdisk.
Selectable main interface for simultanious calibrating of one or two electronic energy meters
