Power requirements
Power is supplied by one 9-volt battery. Battery life is in
excess of 150 hours. A LO BAT message is displayed when
there is less than 20 hours of battery life remaining. The
battery should be replaced immediately after the LO BAT
message is displayed to ensure reliable operation.
The battery compartment is accessed through a screw-
retained panel on the back of the instrument case.
Remove the battery by lifting on the end of the battery
with the terminals. Insert the new battery by pushing
straight down on the battery; do not try to insert at an
angle. Instruments are fitted with a snap-on connector;
simply align the male and female contacts and snap onto
the battery.
Although typical battery life is more than 150 hours of
continuous operation, it is dependent upon the storage
temperature. Do not store the LI-250A at high tem-
peratures.
In some instances, the internal storage is not retained
when the batteries are removed or when the batteries
become discharged. If the LI-250A is reading 0.0 after
replacing the batteries, check the multipliers stored in the
instrument and verify that they are correct for each sensor.
Re-enter them if necessary.
