To prolong battery life, switch your meter off after use. However, the
meter has an auto-shut off feature that will turn itself off after 10
minutes of non-use.
A "V" on the LCD indicates low voltage and the
battery should be replaced.
If the battery is not replaced immediately, in
order to prevent erroneous readings due to low
voltage "-BA-" is displayed soon afterwards.
At this point, the meter will completely lockup and will not allow any
commands and the display will go blank.
Battery replacement must only take place in a non-hazardous area
using a 9V alkaline battery.
Simply slide off the battery cover on the back of the meter. Detach the
battery from the terminals and attach a fresh 9V battery while
paying attention to the correct polarity. Replace the battery and the
cover.
The meter will turn on automatically when a new
battery is connected. You can turn it off by pressing
ON/OFF.
