GASKETS
Four gaskets seal the gauge from the environment. If the gauge has been
out in extremely wet or humid weather, or was used in a cold environment
and stored in a heated space, condensation may form on the inside of the
gauge. Normally, this is not a problem and the condensation will dissipate
overnight.
However, after using the gauge in any of the above conditions, it is
recommended that the display panel be removed to allow air to circulate
inside the gauge. Placing the gauge in a humidity-controlled or air-
conditioned room and loosening the display panel screws will allow the
gauge to “breathe”, reducing any moisture accumulation. A hair dryer (on
low heat) may also be used to dry out the inside of the gauge.
NOTE
All gaskets may be replaced without removing the sources
from the gauge.
To replace the control panel gasket, loosen the four screws and remove the
control panel. Use care in handling the panel, trying not to touch the back
of the circuit board. Unplug the connector from the keypad/display and
remove the panel completely. Remove the old gasket and install a new
gasket. Reassemble the connectors and panel.
To replace the two post gaskets and the top shell gasket, remove the four
screws that hold the top shell to the base. Lift up the base, remove the
gasket in question, and replace with a new gasket. A light coating of
talcum powder on the inside of the post gasket will aid in re-assembly.
CAUTION
High moisture levels inside the gauge may result in
damage to the electronics, as well as erratic or fluctuating
moisture readings.
