Measuring Resistance

(Figure 5)
To avoid damages to the Meter or to the
devices under test, disconnect circuit power and
discharge all the high-voltage capacitors before
The resistance ranges are: 400 Ω, 4 kΩ, 40 kΩ, 400 kΩ,
4 MΩ and 40 MΩ.
To measure AC Voltage,
connect the
follows:
1. Insert the red test lead into
the
and the black test lead into
the COM terminal.
2. Set the rotary switch to Ω.
3. Connect the test leads
across with the object being
measured.
value shows on the display.
Note:
• The test leads can add 0.1Ω
to 0.2Ω of error to resistance measurement. To obtain precision
readings in low-resistance measurement, that is the range of
400Ω, short-circuit the input terminals beforehand, using the
relative measurement function button REL
subtract the value measured when the testing leads are short-
circuited from the reading.
• If Ω reading with shorted test leads is not: ≤0.5Ω, check for loose
test leads, incorrect function selection, or enabled Data Hold
function.
• For high-resistance measurement (>1MΩ), it is normal to take
several seconds to obtain a stable reading.
• The LCD displays OL indicating open-circuit for the tested resistor
or the resistor value is higher than the maximum range of the
Meter.
• When resistance measurement has been completed, disconnect
the connection between the testing leads and the circuit under
test, and remove the testing leads away from the input terminals
of the Meter.
