1. Insert the red test lead into the HzV
ȍ
terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to

, resistance
measurement (

) is default (or press SELECT
button to select
ȍ
measurement mode)
3. Connect the test leads with the object being
measured.
The measured value shows on the display.
Note
z
The test leads can add 0.1

of error to
resistance measurement. To obtain precision
readings in low-resistance measurement, that is
the range of 400.0
ȍ
, short-circuit the input
terminals beforehand, using the relative value
function button
RESET to automatically
subtract the value measured when the testing
leads are short-circuited from the reading.
z
For high-resistance measurement (>1M
ȍ
), it is
normal taking several seconds to obtain a stable
reading.

If

reading with shorted test leads is not

,
check for loose test leads, incorrect function
selection, or enabled Data Hold function.
z
The LCD displays OL indicating open-circuit for
the tested resistor or the resistor value is higher
than the maximum range of the Meter.
z When resistance measurement has been
completed, disconnect the connection between
the test leads and the circuit under test.
