Measurement
To ensure safe operation, be sure to read "Operating Precautions" (p.
12) before starting the measurements.
Internal battery resistance varies considerably depending
on charge or discharge status. To increase measurement
accuracy, make measurements under similar conditions (for
example, a fully charged battery).
Lead-acid batteries (measuring objects) have high levels of
terminal resistance. For this reason, resistance values may
differ between the case and the tip of the terminal. Be sure to

For more information, see "Effects of Current Density" (p. Appx.5).
Use the optional model 9460 Clip Type Lead with Temperature
Sensor to measure the battery temperature. Or, use a non-
contact thermometer, such as a radiation thermometer, for
safety.
Measurement may not be possible for insulated terminals, due
