Battery replacement
When the battery is running out, the
battery mark lights up at the left side of
the display. Replace all 4 batteries (AA)
with new ones.
Those batteries are gradually discharging
even when the tester is not used.
It is recommended to always use new
batteries.
Place batteries in
the correct polarity
Let the tester temperature be the
temperature of the test sample.
PR-930 is equipped with a temperature
compensation circuit. However the
test unit and samples are required
to be thermally stabilized before
measurement.
