On the 945/945M and
965/965M units only, you can
press the # (pound key) to
switch the display from loop
current to station ground
resistance and back.
Disregard this step
if the unit is on.
Note:
On some floating-tip switches such as #5 ESS, ground
resistance cannot be measured because the switch operates
on a floating ground.

To measure RING TO GROUND current, move the black
lead and connect it to ground. The unit automatically makes
the measurement and displays the result.
