ZD2C Contact Resistance Tester

Measure the resistance of circuit breaker contacts, switchgear contacts, and bus-bar joints. Resistance is calculated using Ohm’s law (R = U/I).

FEATURES:

1. Set the output current test duration between 1s and 60s.
2. Enter the device number to conveniently check and identify results.
3. Displays current, test time, and resistance during testing.
4. Stores up to 500 test results.
5. Built-in clock records the date.
6. Stored results include the device number, testing time, and resistance.
