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.

KEYPAD FUNCTIONS

Turns the gauge on and off. When pressing the

ON/OFF

ON/OFF key while in the off position, gauge startup display first indicates the software version followed by the model number and gauge pressure range. The gauge will then display indicated pressure and be ready for use.

Press this key for one second prior to gauge

ZERO

usage to rezero any initial zero shift. If zero shift

CLR

is greater than programmed zero allowance, the gauge will display OFSET (blinking) for 1 second, 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.

MAX/MIN

The Max/Min key allows review of minimum and maximum pressure values since unit start-up or last push of the clear key. Press key to:

1) Indicate maximum pressure.

2) Indicate minimum pressure.

3) Exit MAX/MIN mode and return the unit to pressure measurement mode. To clear minimum and maximum values press ZERO/CLR key (must be in MAX/MIN mode).

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. For compound gauges, the default setting for zero is set at full-scale vacuum. Full-scale pressure is set at the positive pressure as displayed on the gauge keypad.

For 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.

Changing the bar graph to a pressure other than 0 and 100% of range will also change the 4-20mA output to correspond with the new bar graph pressures for 0 and 100%.

To use GRAPH option: Step 1: Press the MENU key.

Step 5: Press the ENTER key to finalize your choice. The

gauge display will now display SET. After two seconds the screen will display the pressure value for 0% on the top line. The middle line indicates the bar graph at 100% of fullscale. The bottom line will display SET 0.

Step 6: Press the



(up arrow key) or (down arrow

key) on the keypad to increase or decrease gauge value at 0% of range.

Step 7: Press the ENTER key to finalize your choice. The new values for the bar graph and 4/20mA settings have now been saved.

OFF: This option sets the amount of time before the gauge will turn itself off. Offerings are Never*, 30MIN,10MIN, 5MIN, 2 MIN.

To use the OFF option: Step 1: Press the MENU key. Step 2: Press the



Step 5: Press the Enter key to finalize the OFF setting.

UPDATE: This option allows for changing the rate at which

pressure is updated on the display screen. This feature is useful with rapid changes in process pressure that may cause flutter of the display. Options are 100ms*, 1 sec, 500ms and 200ms, updates per second or 100ms*.

Since customer processes vary, update rates should be selected based on the application.

Step 5: Press ENTER to finalize the selection.

DAMP or dampening: with five different options, this mode

allows for taking process pressure readings and averaging them. This option is particularly useful to stabilize minor process fluctuations. The options are NONE*, AVG 8, AVG 6, AVG 4, AVG 2.

Step 1: Press the MENU key until the word dAMP appears. Step 2: Press Enter Step 3: Press the



(up arrow key) or  (down arrow

(This Menu item is only seen on units with the switch option)

SWSET: Allows for setting switch setpoints. The gauge is offered with one or two SPDT switches. If (one) SPDT switch is ordered the menu option is SW1. If (two) SPDT switches are ordered, the MENU options are SW1 and SW2.

Step 1: Press the MENU key.



Step 2: Press the

(up arrow key) or (down arrow

key) on the keypad to select the switch to be set. (If two switches are present.)

Step 3: Press ENTER. The top line of the gauge display will indicate pressure at 60% of the fullscale gauge range* or the most recent switch setpoint. The middle line of the display will indicate a bar graph that displays the pressure position within the pressure range. The bottom line will display SETPT (blinking).

*Indicates default.

Note: Setpoints are limited to the full-scale pressure range of the gauge.

Step 4: Press the



(up arrow key) or (down arrow key)

on the keypad to increase or decrease switch set-point 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.

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 4

⁄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 (4

⁄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 (4

⁄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.
