Measuring Resistance
WARNING!
Do not attempt to make resistance measurements with
circuit energized. For best results, remove the resistor
completely from circuit before attempting to measure
it. Make sure the temperature probe is NOT plugged in
during this test.
NOTE:
To make accurate low ohm measurements, short the
ends of the test leads together and press the REL but-
ton to store the reading. This will deduct the stored
value from subsequent measurements eliminating the
test lead resistance from the reading.

ment Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the COM input jack.
3. Plug red test lead into V/
WW
input jack.
4. Set the rotary switch to the
WW
function.
5. Connect test leads to circuit to be measured.
6. Read the resistance value on the EEDM575D.
Optional Modes
