Battery Replacement
Unscrew the two screws at the base of the instrument
and slide off the battery cover. Replace the battery with
a 9V PP3 type battery. Replace the battery cover taking
care not to over tighten the two screws.
Silicone Version
Although C9500 instruments are generally used for gas/
air measurement, special versions are available with
silicone protection to allow liquid pressure measurement
without sensor corrosion.
