Measuring Batteries (Inspection)
Measurement error
Even if the [−−−−] segments appear and the [OVER] segment
blinks on the display (at the same time, the maximum display value
blinks), this does not indicate an error.
[−−−−] • If the resistance readout exhibits the [----] segments,
the test lead may be open-circuited.
Otherwise, the instrument cannot perform
measurement because of a failure, such as no current
ows due to a broken test lead.
• The test lead may not be connected correctly to the
target under measurement.
• The resistance of the target under measurement
signicantly exceeds the measurement range.

• Resistance, voltage, or temperature may exceed each
measurable range.
IMPORTANT
When measuring contact resistances of relays or connectors, be
aware that the instrument will generate an open-terminal voltage
of 5 V at maximum. The open-terminal voltage may damage the
oxidized coating on the contacts of targets under measurement,
leading to incorrect measurements.
Warning display
If an overvoltage is input, the instrument will show the [OVER]
segment and the blinking maximum display value on the display,
backlight the display in red, and produce beeps.
