Dissipative (Soft) Grounds
This test verifies proper operation of soft (dissipative) ground monitoring such as
of mats, dissipative plastics, etc.

All other switch positions are unused for this purpose.
Pressing “Soft Ground” push-button switch will result in load with slightly lower
resistance than the alarm threshold.
Procedure
When measuring dissipative grounds, allow some time -- up to 30 seconds --
for the monitor to react properly -- often a delay is built into indication of failure
of soft ground to allow for noise rejection.

Quick Tour of your Checker
Checker uses 9V alkaline battery. Make sure that a fresh battery is installed prior
to performing any test. If you are not planning to use your Checker for a long time,
please remove the battery from the device.
