3. Measurement
For safe and accurate measurements, please read the full manual carefully.
Make sure to pay attention to the following:
Do not measure over DC 100V
battery at impedance
measurement range. This
is to protect from electric shock.
Do not measure over DC 300V
input when measure voltage at
is measurement
range. This is to protect from electric shock.
Do not measure AC voltages
in either testing mode of the unit.
[Caution]
Do not exceed the maximum rated voltage or current of each measuring range.
Exceeding input ratings may cause damage to the tester.
[Note]
Internal resistance of the battery being measured can be done with the system
charging or on open circuit. Low voltage limits should be adjusted to the condition of
the battery at the time the measurements are being made.
In order to increase accuracy of measurements from one inspection to the next, the
measurements should always be taken in the same location. Measurement of batteries
directly on the posts will provide more accurate readings. Hardware, washers and lugs
all add resistance to the measurement values.
Ensure the probe pins are clean and free of dirt, dust, etc. prior to taking
measurements.

“0”
Point Adjustment before Measurement
Zeroing out the test leads prior to use ensures that the resistance of the leads
themselves is not included in the measurements being taken.
“0” adjustment is required when the unit is first set-up, when switching from one set of
test leads to another and periodically to ensure accuracy of readings.
