DJD-309 Switchgear Earth Resistance Tester
Switchgear Grounding Resistance Tester
Model: DJD-309 Switchgear Grounding Resistance Tester
Application:
The DJD-309 Switchgear Grounding Resistance Tester is a universal safety parameter testing instrument. It is used for verifying the grounding continuity of high and low voltage switchgear and the effectiveness of the protection circuit. It is also applicable to measuring the resistance value between the protective grounding terminal and the accessible metal housing of various motors, electrical appliances, instruments, meters, household appliances and other equipment.
Feature:
1. The test current can reach up to 30A.
2. It has a time-setting function with a timer: When a timing value is set and the timing selection switch is set to the timing position, the timing display value of the instrument will start counting down after the instrument is started. Once the timing value reaches 0, the timing will automatically stop and the instrument will reset.
3. It features accurate measurement and convenient operation.
