Measurement 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/Ω input jack.
4. Set the rotary switch to the Ω function.
5. Connect test leads to circuit to be measured.
6. Read the resistance value on the 293.
Optional Modes
•

•
Do not attempt to make resistance measurements with
circuit energized. For best results, remove the resistor
completely from circuit before attempting to measure it.
NOTE:
To make accurate low ohm measurements, short the
ends of the test leads together and record the resistance
reading. Deduct this value from actual readings.
