3M™ Dynatel™ Advanced Modular System 965AMS Measurement Functions
Ohms Measurements>Soak Test
1. Take an initial resistance
measurement by pressing
the
Snap Shot
key.
2. You will compare this to
other active measurements
to determine the source of
the fault.
3. One of the properties of
moisture in a circuit is that
the current from the tester
can “dry out” the moisture.
The display will rst show
a lower resistance, then
after one or two minutes the
resistance will increase to a
higher reading.
This indicates the fault is
caused by moisture.
Note: This is not an
acceptable procedure to
“dry” a fault.
