Besides to the 12 VDC supply, this meter can also be fed by two 9V
batteries.
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 blinking "LOBAT" on the display, while a
measurement is in progress, indicates low
voltage and the batteries should be replaced.
If the batteries are not replaced immedi-
ately, in order to prevent erroneous readings
due to low voltage, "-BA-" is displayed soon
afterwards. At this point the batteries must
be changed.
Battery replacement must only take place in a non-hazardous area
using two 9V alkaline batteries.
Remove the battery cover on the back of photometer, attach two fresh
9V batteries, while paying attention to the correct polarity, and
replace the cover.
The meter will turn on automatically when a new battery is connected.
You can turn it off by pressing ON/OFF.
