CJ1009B Lightning Protection Device Tester
1.1.3 Power：(220±22)V ,(50±2 )Hz，50VA；
Tolerance of the the voltmeter : ±5% of the reading +5digits.
1.2.2 Test current for d.c. reference voltage measurement : 1mA±0.05mA.
1.2.3 Ramp voltage rate: 100V/S ±10% ，1000V/S±10%.1.2.4 Two approaches to start measurement：
2. Safety precautions2.1. Connect reliably the black “Safety Grounding ” terminal on the back panel of the tester to the ground .
3. Operation steps3.1 Connect the tester to the power supply 110V,60Hz.
3.4 Select suitable range “200V/2000V”of the voltmeter according to expected voltage of the DUT, if it is unknown, then the “2000V” range shall be tried at first, in case that the voltmeter showing a reading of less than 200V, then“200V” range should be utilizedNote: The test voltage on the DUT will be cut off by the overvoltage protective circuit in the tester in case that the voltage of the DUT more than 2000V, or that the DUT is not properly connected with the tester.
