The SenSym ICT Digital Pressure Gauge Series
devices are designed for pressure applications that
involve measurement of any media compatible with
316 stainless steel. With its common 1/4" NPT
fitting, the device is designed for many applications
requiring precision, ruggedness and reliability
combined with a long battery life. The digital
readout provides real-time information at the push
of a button.
Designed for battery operation, this digital gauge
has an automatic shutoff feature allowing the user
to walk away after taking a reading. The SenSym
ICT Digital Pressure Gauge Series is designed for
long-term usage. Zero and Span calibration are
both possible, but only when the user has access to
a reliable pressure reference of known accuracy.

Installation
Tighten the gauge by using the wrench on hex
fitting only. Do not tighten it by turning housing!
Use fittings designed for the pressure range of
the gauge. Do not apply vacuum to gauges not
designed for vacuum operation.
Operation
Press the round button on the front of the gauge
to activate the display. The gauge will stay on for
5 minutes. After this time, the gauge will
automatically shut off. The gauge can be shut off
at any time by pressing the button again.
“LOBAT” will appear in the upper left-hand corner
of the display when the battery voltage falls
sufficiently. The battery should be replaced soon
after the LOBAT indicator comes on or unreliable
readings may result.
Calibration
Remove the calibration potentiometer cover on
the front of the unit to access the Zero and Span
controls. The Zero and Span controls are non-
interactive. The gauge port must be open to the
ambient with no pressure or vacuum applied.
Adjust the Zero control until the gauge reads zero
with the minus (–) sign occasionally flashing.
Span calibration should only be attempted if the
user has access to a pressure reference of known
accuracy. The accuracy of the calibration
equipment ideally should be at least four times
the gauge accuracy. Zero calibration must be
done before span calibration. Record readings at
three to five points over the range of gauge and
adjust span control to minimize error and meet
specifications.
Battery Replacement
Remove the six phillips head screws on the back
of the unit. Carefully remove batteries from the
holders by lifting up the positive end of the
battery (opposite the spring). Take care not to
bend or distort the battery retention springs. DO
NOT discard the old battery into fire, any other
sources of extreme heat, or in any other
hazardous manner. Always replace both batteries
at the same time with high quality alkaline
batteries. Observe the polarity of the batteries
when replacing them. The negative (flat) end of
each battery should be inserted first and should
face the spring in the battery holder. Replace the
back cover, including the rubber sealing gasket.
