Product Description

JW－***1A
1 General
This instrument is an integrated 3 phase 0.*5 grade device designed according to < JJG*******5 Verification Regulation of Ammeters, Voltmeters, Wattmeters and Ohmmeters> and . The core technique of meter embedded in this instrument is a high precision industrial frequency AC collector combined by digital signal processor (DSP) and *6 digits high speed A/D converter. The signal part of the source is also the controllable sine wave and harmonic wave signal source combined by DSP and *6 digits high speed D/A converter.
Using a 6.5 inch TFT color LCD screen, character display clear chart. Device has the advantages of high precision, stable and reliable work, convenient operation and flexible features such as.

2 Main functions & features
l This instrument offers an automatic or manual calibration to the basic errors for various kinds of industrial-frequency electric meter (voltmeter, ammeter, wattmeter, cymomer and power factor meter), and measure the variables caused by the effects of the voltage, current, wave form, power factor.
l This instrument offers an automatic or manual calibration to the basic errors for various kinds of transmitter (voltage transmitter, current transmitter, power transmitter, frequency transmitter, power factor transmitter), and measure the variables caused by the effects of the voltage, current, wave form, power factor.
l This instrument can generate harmonic wave with 2~*1 order, and it is can be program-controlled that the quantity and times of the harmonic wave, and the phase angle of the harmonic wave vs. fundamental wave.
l With frequency range of *0Hz～1kHz, the power amplifier has fine linearity; The current amplifier is a constant-current source and the voltage amplifier is also a constant-voltage source. Because of light in weight, this instrument is suitable for on-the-spot calibration.

In the measurement of AC voltage, current, active power, its accuracy is 0.*5 level; because the device is provided with a higher *0KHz working frequency digital to frequency converter ( DFC ) and a plurality of the current range, so the measurement of electrical energy accuracy can also guarantee for grade 0.*5. So,the device, with high precision and stability, combines the testing functions of electrical measuring transmitter, AC/DC ammeter and energy meter (alternative with partial functions can also be customized as required).

l Equipped with USB interface, this instrument can automatically or manually calibrate via upper computer software (optional part), and can process and manage the calibration data.
l Equipped with a high capacity nonvolatile memory, this instrument can save over **0 meters original calibration data for review and upload.
