Congratulations on your purchase of the Ashcroft
®
digital sanitary gauge. This feature-packed gauge
offers a menu-driven display for easy customization.
User selectable features include 12 units of measure-
ment, password protected calibration and disable
functions, adjustable bar graph and update rate. A
five digit display for maximum resolution is standard.
Optional 4-20mA output, switching and line- power
add to the versatility of the gauge. With the range
printed on the keypad, Ashcroft digital gauges meet
ASME B40.7 specification. See a complete listing of
product features and specifications on pages 16.

up display first indicates the software version
followed by the model number and gauge pres-
sure range. The gauge will then display indicated
pressure and be ready for use.
Press this key for one second prior to gauge
usage to rezero any initial zero shift. If zero shift
is greater than programmed zero allowance, the
gauge will display O SET (blinking) for 1 sec-
ond, then return to the measure mode. To clear
minimum and maximum values, press
ZERO/CLR button (when min/max values are
indicated). Gauge will auto advance once zeroed.

Step 5: Press ENTER To finalize the setting.
GRAPH: This option allows the user to change the BAR
graph on the gauge display to correspond to any desired
pressure within the pressure limits of the gauge. This
option is useful when identifying a select portion of the
full-scale range of the gauge. The default setting for the
GRAPH is zero and full-scale pressure. or compound
gauges, the default setting for zero is set at full-scale vacu-
um. ull-scale pressure is set at the positive pressure as
displayed on the gauge keypad.
or gauges supplied with the 4-20mA output option, the
default is 4mA equals 0% of the bar graph and 20 mA
equals 100% of the bar graph.
Ch nging the b r gr ph to pressure other th n 0 nd
100% of r nge will lso ch nge the 4-20mA output to cor-
respond with the new b r gr ph pressures for 0 nd 100%.

Step 5: Press the ENTER key to finalize switch setpoint. The
gauge will display SET. After two seconds, the top line will
indicate RETRP pressure. The bottom line will read SET.
Step 6: Repeat above to set RETRP (retrip value) If the
gauge is supplied with (one) setpoint, the screen will
advance to the measurement mode. If (two) switches are
supplied the display will advance to SW2.
Repe t the forementioned if the g uge is supplied with
two switches.
Notes: The b r gr ph will incre se or decre se s ny
setpoint pressure is djusted. The b r gr ph indic tes
switch setpoint position within the full-sc le pressure

The switch setpoint unit of pressure measurement corre-
sponds 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.

Battery Installation and Replacement:
The Types 2032 & 2036 comes standard with batteries installed. These gauges use
qty (2) AA alkaline batteries. Use alkaline, non-rechargeable batteries only.
Batteries have a life of approximately 1500 hours. 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:
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 provide m ximum b ttery life, repl ce both b tteries.
Notes:
1) Do not mix ages or brands of batteries.
2) Do not replace batteries in hazardous areas.
