Measurement Example
For Use in Shipping Inspections Measure Insulation Resistance and Withstand Voltage
Insulation deterioration leads to the risk of electric shock and ground faults.
The condition of insulation is tested during shipping inspections to ensure product safety.

Results of Insulation Deterioration
- Risk of Electric Shock
- Risk of Ground Faults

Contact Check Function to Ensure Reliable Testing
Incomplete probe contact and wire breaks in cables can prevent proper contact with the device under test. In such cases, defective parts can be misidentified as non-defective. Contact check functionality provides an effective means of ensuring test integrity.

Instruments Used

AUTOMATIC INSULATION/WITHSTANDING HiTESTER3153
Contact checks can be performed continuously without affecting measured values.
・AC Withstand Voltage Testing: 0.2 kV to 5 kV AC, 100 mA
・Insulation Resistance Testing: 50 V to 1200 V DC, 0.100 MΩ to 9999 MΩ
