Direct high voltage digital tester

1Digital display voltage testerOverview:

The high-voltage direct tester is a product independently developed by our company using imported components, with reliable performance. All parameters are our company's enterprise standards.

The direct tester adopts the structure and process of the cross tester for both the indicator and the operating rod, with the difference being the operating rod of the direct tester

A digital voltmeter and a grounding socket have been added to connect the grounding wire, and there is no positive or negative polarity at the grounding terminal.

two、Direct high voltage digital testerParameter: (Straight)

Rated voltage: ± 1.5 KV, starting voltage:±0.001 KV。

Limit voltage resistance:± 1.9 KV。， Operating rod withstand voltage: 45 KV/1 min.

IIIDirect high voltage digital testerEnvironmental conditions for use:

Direct testing electrical environment temperature: -25 ℃~+55 ℃

Application scenarios for direct testing appliances: no rainy weather indoors or outdoors, with a relative humidity of less than 85%.

4Direct high voltage digital testerUsage and precautions:

1. To ensure the safety of personnel and equipment, and to ensure the integrity of the voltage tester, it should be stored in a well ventilated and dry environment.

2.Before conducting an electrical test, the tester should be self checked. The method is to turn on the power switch and the digital display should quickly reset to zero. Do not perform electrical testing without instructions. Before conducting electrical testing, it is also necessary to check whether the grounding lead is intact and whether the contact points are reliable.

3.The sequence of electrical verification operations is:

(1) Stretch all insulated operating rods until they are fully pulled and positioned. Insert the digital display into the bottom marking line of the second section of the insulation rod.

(2) Insert the plug at the top of the test line reliably into the socket at the end of the first pole, and plug the other end into the red test socket of the digital display meter.

(3) Insert the plug of the grounding lead into the black socket of the digital display, and securely clamp the other end onto a good grounding rail or pole.

(4) The operator should test the electricity of the voltage tester on the electrified part to prove that the performance of the voltage tester is intact, and then test the electricity on the construction part to confirm whether the construction part is electrified.

Note:Electrical testers should be stored in dry environments, and battery replacement should be considered as the first option when the display is abnormal. The battery inside the digital display should be replaced every six months to prevent damage to components due to battery leakage.
