4.6 Automatic Discharge

When insulation resistance test is performed on equipment
to be tested containing capacitance, test voltage load is
charged during testing which may result in electric shock.
Use automatic discharge function to discharge buildup
charge through the 3154 internal circuit.
After testing, follow the instructions below to discharge.
(1) End testing without removing both test probes from
(2) The 3154 internal discharge resistance unit enables
(3) During discharge, TEST lamp blinks.
(4) When voltage goes below approximately 10 V, TEST
Safe to set and verify test condition setting or press START key
NOTE
to restart testing while TEST lamp is still blinking.
When the 3154 power supply is turned OFF, discharge
resistance is approximately 12 MΩ .

Internal discharge resistance is approximately 2 MΩ .
Larger amount of capacitance requires longer discharge
time.
