advance to the measurement mode. If (two) switches are
supplied the display will advance to SW2.
Repeat the aforementioned if the gauge is supplied with
two switches.
Notes: The bar graph will increase or decrease as any
setpoint pressure is adjusted. The bar graph indicates
switch setpoint position within the full-scale pressure
range of the gauge.
The switch setpoint unit of pressure measurement corresponds with the current set unit of measure of the gauge.
If gauge unit of measurement is changed after switch(es)
is set, switch setpoint(s) will automatically be updated to
correspond with revised unit of measurement. Switch
deadband is the difference between the SETPT (setpoint)
and the RETRP (retrip) pressure.

GAUGE INSTALLATION:
The Ashcroft digital sanitary gauge comes standard with a
Tri-Clamp connection. Install the Tri-Clamp fitting to the
mating fitting using a gasket compatible with the process
media and clamp (mating fitting, gasket, clamp provided
by others).
NEVER TIGHTEN GAUGE THREADS BY HOLDING THE
BODY OF THE GAUGE. DOING SO MAY DAMAGE THE
GAUGE AND MAKE THE GAUGE INOPERABLE.
Battery Installation and Replacement:
The Type 2032 comes standard with batteries installed.
The 3˝ case uses qty (2) AA alkaline batteries, the 41⁄2˝ case
uses qty (2) C alkaline batteries. Use either Duracell
MN2400, MX2400 or Energizer E92BP, X92RP AAA alkaline, non-rechargeable batteries.
Batteries have a life of approximately 1500 hours (3˝ case).
3600 hours (41⁄2˝ case). Battery life is dependent on gauge
usage, backlite settings and power off settings. When the
lower bar of the battery icon of the gauge display flashes,
the gauge has approximately 7 hours of life remaining.
To replace the batteries (3˝ case):
1) Remove the single screw on the back of the gauge case.
2) Hold the keypad in the palm of hand.
3) Carefully remove the two batteries from the holder and
replace batteries. Use only AA alkaline non-rechargeable
batteries
To replace the batteries (41⁄2˝ case):
1) Remove the ring on the front of the gauge case.
2) Looking at the gauge case, carefully pull the front face
out of the case.
3) Lay the gauge, face down on a flat surface.
4) Carefully remove the two batteries from the holder and
replace the batteries. Use only C alkaline non-rechargeable batteries.

ESD PRECAUTIONS
Care should be taken to minimize exposure to ESD.
Proper proto-call should be followed as outlined in:
ANSI/ESD S20.20-2007
ESD ADV1.0-2009
ANSI/ESD S541-2008
Additional ESD Precautions on Proper Handling:
Avoid carpets in cool, dry areas as well as other static
generating materials such as plastic, cellophane, paper, or
cardboard.
Leave digital gauges in their anti-static packaging until
ready to be installed.
Dissipate static electricity before handling the digital
gauge or using keypad by touching a well-grounded metal
object, such as the system unit unpainted metal chassis.
If possible, use antistatic devices, such as wrist straps and
floor mats.
When installing batteries, avoid touching (including clothing) the contacts and components.
When making wiring connection to digital gauge terminals, place digital gauge on grounded mat prior to making
connection, and take care to avoid touching (including
clothing) any components.
Take care when connecting or disconnecting cables. A
damaged cable can cause a short in the electrical circuit.
When disconnecting a cable, always pull on the cable connector, case, or strain-relief loop, not on the cable itself.
– 31 –
Notes:
1) Do not mix ages or brands of batteries.
2) Do not replace batteries in hazardous areas.
3) To provide maximum battery life, replace both batteries
4) To provide maximum battery life, replace both batteries.
Pipe to which gauge is attached must be properly
grounded.
