I. Overview

HZJD8001 Single AC DC Standard Source (hereinafter referred to as calibrator) is an intelligent standard source of AC and DC voltage and current. (AC output is true RMS display) three windows of the calibrator simultaneously display the output actual value, percentage and full scale value of the meter to be tested; the full scale value of the meter to be tested can be set; the corresponding step can be selected according to the scale of the meter to be tested; two modes of amplitude adjustment can be selected: digital key or analog adjustment (encoder); digital display, error direct reading, wide range, fine grading and high precision It's high stability and easy to use. The calibrator is suitable for verification, calibration and repair of digital multimeter, voltmeter and ammeter with less than four and a half digits, as well as all kinds of pointer type multimeter with less than 0.2 level, AC and DC voltmeter and ammeter; it can also be used as high stability test power supply, cooperating with high-level standard meter to calibrate ammeter and voltmeter with 0.1 level. The instrument is equipped with USB interface, which can be connected with computer to realize data transmission and printing.

II. Main Functions

2.1 six digit LED digital display output value in two ways: actual value and percentage

At the same time.

2.2 press the key to adjust the increase or decrease of the output value to facilitate the detection of digital instruments. There are two adjustment modes: the percentage adjustment according to the range and the display digit adjustment corresponding to the key.

2.3 adjust the increase or decrease of output value to facilitate the detection of pointer instrument. The simulation adopts encoder adjustment, which can be adjusted in any mode of percentage adjustment and position adjustment.

2.4 the output range of AC and DC voltage is 0 ~ 1050V.

2.5The output range of AC and DC current is 0 ~ 24a.

2.6 there are four alternative AC frequencies: Mains synchronous, 50 Hz, 60 Hz(59.7Hz), 400 Hz and 1 kHz (crystal oscillator oscillation frequency is stable).

2.7 output overload automatic protection and manual reset.

2.8 AC 50 Hz output can select the power synchronization to reduce the impact of beat frequency.

2.9 clamp ammeter measurement: equipped with our standard coil, it can measure 0 ~ 1000A clamp ammeter with an error of ± 0.3%.
