Taking care of your LCR40
Battery Replacement
The LCR40 requires no special maintenance
although the battery should be replaced at least
every 12 months to prevent leak damage.
If this message is displayed, the battery
should be replaced as soon as possible to
prevent malfunction or leak damage.
Although the unit may continue to
operate following a low battery warning, measurements may be adversely
affected.
Battery types: Suitable battery types include 23A, V23A, GP23A, MN21,
L1028 or a good quality 12V alkaline equivalent as used in many test
instruments and automotive remote key fobs.
Battery access: To replace the battery, place the instrument face-down on a
smooth surface and then unscrew the three screws to remove the rear panel.
Remove the old battery and insert a new one, taking care to observe the
correct polarity. Carefully replace the rear panel, do not over-tighten the
screws.
The GP23A type battery will typically last for about 27 hours of
operation which equates to about 1600 operations of 1 minute duration
(1 minute is the auto-power-off period). You can improve battery life by
switching off the LCR40 before the auto-power-off period expires by
pressing and holding the scroll-off button.
