Resistance Measurement; Continuity Check By Sounder - Iso-Tech IDM63N Instruction Manual

UNSTABLE DISPLAY MAY OCCUR ESPECIALLY ON THE 300mV RANGE, EVEN IF THE TEST
NOTICE :
LEADS ARE NOT CONNECTED TO THE METER. IN THIS CASE, IF AN ERRONEOUS READING IS
SUSPECTED, SHORT THE "VΩ" TERMINAL AND THE "COM" TERMINAL AND MAKE SURE THE
DISPLAY READS ZERO.

3-3 Resistance Measurement

1. Connect the red test lead to the "VΩµA" terminal and the black test lead to the "COM" terminal.
2. Set the function switch to "Ω" position.
3. For correct reading, ensure that the device being tested has no voltage present.
4. Connect the test leads across the resistor to be measured. To ensure the best accuracy in measurement of low
resistance, short the test leads before measuring and note the test lead resistance. It is necessary to subtract
the resistance of the test leads from the displayed reading.

3-4 Continuity Check by Sounder

1. Connect the red test lead to the " VΩ µA " terminal and the black test lead to the "COM" terminal.
2. Set the function switch to "
3. Connect the test leads to the circuit to be measured. The sounder will operate if the resistance of the circuit
measured is less than 20Ω.
