Leakage Current

The leakage current is tested by measuring the voltage across the input channel.
Test limit
DC 1MΩ : ±1 mV
5.5.1 Channel Leakage Current
! Recall xxxP010.PNL or configure the DSO:
! Set the DMM to measure Volts, and connect it to Channel 1.
! Measure the voltage and enter it in Table 3. Compare it to the limits.
! Repeat the test for all input channels.
