KEYPAD FUNCTIONS
Turns the gauge on and off. When pressing the ON/OFF ON/OFF key while in the off position, gauge start-
up 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.
ZERO CLR
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 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 mini- |
|
|
mum and maximum values press ZERO/CLR |
|
|
key (must be in MAX/MIN mode). |
|
|
The (down arrow key) is used in the MENU |
|
|
mode, see following MENU key section. |

KEYPAD FUNCTIONS
This key allows for customization of the gauge. Pressing the MENU key allows cycling through the main MENU items; UNITS, CONFIG, GRAPH, OFF, UPDAT & DAMP. Any item changed in the Menu become the new default setting(s). Revised settings are saved in the event of power loss.
The (up arrow key) or (down arrow key) on the keypad allows for scrolling through the MENU options to increase or decrease numeric values as required. If in the menu mode, gauge will automatically advance to measure mode once selected MENU item has been set.
This key manually turns the backlite on or off. Five options are available. They include NEVER, 10 sec, 30, sec, 1 min, 5 min*. With the NEVER option, the gauge BACKLITE will remain lit whenever the gauge is in the ON mode or until the BACKLITE button is pushed again. Options, 10 sec, 30 sec, 1 min, 5 min*. allow the BACKLITE to automatically turn-off after a selected period of time.
To use the BACKLITE option: Step 1: Press the MENU key.
Step 2: Press the (up arrow key) or (down arrow key) until the word LITE appears.
Step 3: Press ENTER.
Step 4: Press the (up arrow key) or (down arrow key) to select the BACKLITE option.
Step 5: Press the ENTER key to finalize your choice of LITE options.

KEYPAD FUNCTIONS
This key allows for selecting gauge features in the ENTER menu finalizing selection. Use of the enter key is
described throughout operating instructions.
MENU OPTIONS
UNITS: 12 units of measurement are available: psi, mmHG, inH2O with three temperature options: 20°C, 60°F, 4°C*, mBar, inHg, ftH2O, mPa, kPa, kg/cm2 and bar.
Step 1: Press the MENU key until the word UNITS appears. Step 2: Press ENTER.
Step 3: Press the (up arrow key) or (down arrow key) to select the required unit of measure.
Step 4: Press ENTER to finalize the UNIT selection.
Note: For inH20 range with three temperature options, press the (up arrow key) and (down arrow key) to select the desired temperature, then press ENTER to finalize the UNIT selection.
CONFIG: This option allows access to additional Menu options. Options include:
•ENTPW or enter password (this appears as a sub-menu in the CONFIG mode if a user password has been set).
•RECAL (allows for zero, span and mid-scale calibration of the gauge).
•0bUTN or zero key (allows for adjustment of % of range that can be zeroed),
•dISAb, allows for disabling MENU options.
•SETPW: This feature allows for a user defined numeric password. If a user password is not set, all features in the CONFIG mode will be accessible without a password. If a user password is set, all items in the CONFIG menu options are accessible with or without a user password. If a user password is programmed, it will be required to access the CONFIG menu options. Default user password is 12045 or 12*45.
*Indicates default.

MENU FUNCTIONS
How to Use Your Menu Functions To set a user password (SETPW):
Step 1: Press the MENU key on the keypad
Step 2: Press the (up arrow key) or (down arrow key) until the word CONFIG appears.
Step 3: Press ENTER. The word SETPW appears on the gauge display
Step 4: Press ENTER. A five digit numeric password is now required.
Step 5: Press the (up arrow key) or (down arrow key) on the keypad to select the first digit of the password.
Step 6: Press ENTER.
Step 7: Repeat until the five-digit password is shown on the gauge display.
Step 8: Press ENTER.
Note: to erase password at any time while in the SETPW (set password) mode, press the ZERO/CLEAR key. The user will be prompted to reprogram the password once the five-digit password is entered. The gauge will display SAVE.

ENTPW: Once a user password has been established and entry into the CONFIG mode is required, the user will be prompted to ENTPW or enter password.
Follow setup steps 4-8 above.
RECAL: or recalibrate allows for zero, mid-scale, full-scale and factory default calibration of the gauge. The RECAL feature also allows for recalibration of gauges with 4-20mA output.
*Indicates default.

MENU FUNCTIONS
To use RECAL option:
Step 1: Press the MENU key on the keypad
Step 2: Press the (up arrow key) or (down arrow key) on the keypad until the word CONFIG appears.

Step 4: Enter user password if it has been programmed.
Step 5: Press (up arrow key) or (down arrow key) until the word RECAL appears.
Step 6: Press ENTER.
Step 7: The gauge will now flash between INPUT and unit of measure on the lower line and .00 on the top line. Apply zero pressure to the gauge.
Step 8: Press ENTER. Zero pressure is now set.
Step 9: The gauge will display full-scale pressure. Apply full-scale pressure to the gauge.
Step 10: Press ENTER. Full-scale pressure is now set.
Step 11: The gauge will now display mid-scale pressure. Apply mid-scale pressure to the gauge.
Step 12: Press ENTER. Mid-scale pressure is now set.
Step 13: After zero, full-scale and/or mid-scale or factory default calibration have been set, the word SAVE appears on the gauge display.
Step 14: Press ENTER to finalize calibration.
(Note: For compound ranges this recalibration is zero, full-scale, mid-scale and full-vac.)
FOR FACTORY CALIBRATED SETTINGS:
To reinstate factory settings for zero, full-scale and midscale follow RECAL steps 1-6
Step 7: When the word INPUT appears press (up arrow key) until the word FACT appears.
Step 8: Press ENTER to finalize calibration.
