ERENCE Press to turn unit on or off Press to turn backlite on or off Flashing display when unit pressured beyond full-scale This bar graph indicates battery level; the more segments, the closer the battery is to full charge Range on keypad; complies with ASME B40.7 While in unit of measurement mode (eg: psi), press the ZERO CLEAR button to rezero the gauge.
KEYPAD FUNCTIONS ON/OFF BACK LITE MAX MIN ZERO CLR ENTER CONFIG Turns the gauge on and off. When pressing the 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. Manually turns backlite on and off. (See CONFIG mode for options). Allows review of minimum and maximum pressure values since unit start-up or last push of the clear button.
KEYPAD FUNCTIONS UNITS: 12 units of measurement are available, both English and metric, by cycling through the UNITS key; psi, ˝Hg, ˝H2O (with three temperature options, 60°F, 4°C and 20°C), ftSw, Bar, mBar, kPa, mPa, mmHg, cmH2O, mmH2O, kg/cm2. Step 1: Press the CONFIG key until the word UNITS appears. Step 2: Press the ENTER key. Step 3: Press the CONFIG key once to select ENGLISH or again to select METRIC. Step 4: Press the ENTER key with selection of ENGLISH or METRIC.
KEYPAD FUNCTIONS To use the AUTO OFF option: Step 1: Press the CONFIG key until the word AUTO OFF appears. Step 2: Press the ENTER key. Step 3: Press the CONFIG key to select the desired AUTO OFF rate. Step 4 Press the ENTER key to finalize the AUTO OFF rate. BACKLITE: 5 options are available. They include ON/OFF*, 10 seconds, 30 seconds 1 or 5 minutes. With the ON option pressed, the gauge backlite will remain lit whenever the gauge is in the ON mode or until the backlite button is pushed again.
KEYPAD FUNCTIONS DAMPING: with six different options, this mode allows for taking process pressure readings and averaging them. This option is particularly useful when there is pulsation in the process. The options are NONE*, AVG 2, 4, 6 or 8. Step 1: Press the CONFIG key until the word DAMPING appears. Step 2: Press the ENTER key. Step 3: Press the CONFIG key to select one of the available DAMPING options. Step 4: Press the ENTER key to finalize your DAMPING option.
KEYPAD FUNCTIONS To access the factory default password: Step 1: Press the CONFIG key until the word CALIBRAT appears. Step 2: Press the ENTER key. Step 3: The letters/asterisks… PW***** appear. Step 4: Press the CONFIG key. An Ø appears in the first position. Step 5: Press the ENTER key once. Step 6: Press the CONFIG key until Ø appears. Ø will appear in the second position. Step 7: Press ENTER. Step 8: Use this format until all the asterisks are replaced with Ø.
KEYPAD FUNCTIONS Zero Calibration: Step 14: Press the CONFIG key once and the word CALIBRA appears. Press ENTER. (This mode allows for 0 and full- scale adjustment of span.) The gauge will now display 0.00. Ensure the gauge is not pressurized,1 then press ENTER to zero the gauge. Zero calibration is now complete. Full Scale Calibration Step 15: The gauge will now display full-scale range (e.g. 100.00 psi).
KEYPAD FUNCTIONS Step 1: Press the CONFIG key until the word ZERO SP appears. Step 2: Press ENTER. Step 3: Enter user five digit password (PW). This is the same password established to access the CONFIG mode in the menu. Step 4: Press the CONFIG key to select the desired option. Step 5: Press ENTER to finalize the selection. Notes: Selecting the DISAB feature does not disable the CLEAR button on the keypad for the MAX/MIN feature.
KEYPAD FUNCTIONS If the user password is lost or stolen, contact Ashcroft Inc., customer service at (203) 3788281 for a new factory password that will allow the user to establish a new user password. DISABLE: allows “lockout” of individual CONFIG options. The default is ENABLE for all options in the CONFIG mode. Step 1: Press the CONFIG key until the word DISABLE appears. Step 2: Press the ENTER key. Step 3: Insert the user password following the procedure as described in steps 3 through 13 above.

Gauge Installation: Pipe Mount – The Ashcroft digital test gauge comes standard with a 1⁄4 NPT connection. Good piping practices recommend using teflon tape or a pipe sealant on the gauge threads. Utilize a 7⁄16˝ wrench on the wrench flat of the gauge to tighten the gauge to the process. NEVER TIGHTEN GAUGE THREADS BY HOLDING THE BODY OF THE GAUGE. DOING SO MAY DAMAGE THE GAUGE AND MAKE THE GAUGE INOPERABLE.
