Technical parameters
Nominal discharge current : | 10kA 8/20μs wave |
Residual voltage : | 0.8kV peak |
under nominal discharge Current Long duration current impulse withstand : 800A 2ms wave Maximum high current withstant : 100kA 4/10μs wave Minimum count current : 20A 8/20μs wave Over-current withstand capacity : 100mA 48~62Hz Meter scale : 0~3mA even Counter : 3 digit cyclometer under continuous operating Voltage : <3V |
Test of monitors:
Charge the 10μF capacitor until the voltage reaches 300V at least and on more than 600V, then discharge the capacitor to the monitor ,making sure that the meter adds digit 1 to its original figure.
Test of the milliameter:
Connect a digital multmeter to the two terminals of the instrument, making sure that its hand points to several hundreds of μA.
