6.3. Resistance measurements
WARNING! Attempting resistance or continuity measurements on
live circuits can cause electric shock, damage to the instrument and
damage to the equipment under test. Resistance measurements
must be made on de-energized (DEAD) circuits only for maximum
personal safety. The electronic overload protection installed in this
instrument will reduce the possibility of damage to the instrument bus
not neces-sarily avoid all damage or shock hazard.
1. Turn off any power to the resistor to be measured. Discharge
capacitors. Any voltage
measurement will cause inaccurate readings and could damage
the meter if exceeding the overload protection of 250 V DC or
AC.
2. Insert the black and red test leads into the COM and V/Ω input
terminals respectively.
3. Select the desired ohm (Ω) range.
4. Connect the black and red test probe tips to the circuit or device
under test, making sure it is de-energized first.
5. Open circuits will be displayed as an overload condition.
6. Test lead resistance can interfere when measuring low
resistance readings and should be subtracted from resistance
measurements for accuracy. Select lowest resistance range and
make the test leads short together.
The display value is the test lead resistance to be subtracted.
7. After completing measurement, disconnect the DCM test leads.
