t ................. Discharging time
Up ............. Peak voltage of supply during the test

Test parameters

Limit voltage

Limit U [60 V, 120 V]

Output connections

Output [External, Socket]

Test mode

Mode [Manual, Auto]

Delay time for AUTO mode Delay [2 s ... 30 s]

Test limits

Discharging time limit

Limit(t) [1 s, 5 s ]

Measuring principle (Output = External)

The measuring principle of the Discharging time function is as following:

Phase



The device under test is connected to supply voltage via an external socket. The
instrument monitors the voltage (on supply or internal connections) and internally
stores the peak voltage value.
