Purpose
The digital high-volt meters are mostly used for measuring the high voltage in the power frequency and DC. It can directly read the volt of DC or AC through the special digital meter, which is measured the low signal divided through cable, the digital highvolt meters of our company passed the inspection of the national high volt metering station, the certificate of inspection is 971153, 97001.The license number of the metering manufacture is 01000289.
Reference-standard
DL474.1～6—92 The Guide Line of Insulation Testing Implement in the Work Place
ZBF24002 The Using Guide Line of Volt Withstand Test Equipment DC and AC using in the work place
Technical criteria
(1) Accuracy: 1.5%
(2) Voltage ratio K=High Volt/Low Volt=1000:1
(The measured high Volt=1000×Volt of the low meter)
(3) Voltage:1.2×The rated voltage
(4) Environment Condition : Temperature 0～40℃，Relative Humidity＜ 85%
