Safety Information
A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies
conditions and procedures that can cause damage to the Product or the equipment under test.
                                              W Warning
    To prevent possible fire, explosion, or personal injury:
    • Read all safety information before you use the Product.
    • Carefully read all instructions.
    • Do not alter the Product and use only as specified, or the protection supplied by the
      Product can be compromised.
    • Do not use the Product if it operates incorrectly.
    • Do not use the Product if it is altered or damaged.
    • Disable the Product if it is damaged.
    • Avoid any action that can generate an electrostatic charge. Electrostatic discharge is an
      explosion hazard.
    • Clean the Product only with a damp cloth.
    • Do not rub the non-metallic parts of the enclosure (display overlay or holster) with a dry
      cloth. This action can create an electrostatic discharge.
    • Only assemble and operate high-pressure systems if you know the correct safety
      procedures. High-pressure liquids and gases are hazardous and the energy from them
      can be released without warning.
    • Do not use the RS-232 interface in hazardous areas. The RS-232 interface port must be
      sealed when used in a hazardous area.
    • Substitution of components can impair suitability for hazardous locations.
    • If the Product is exposed to overpressure or sudden physical shock (such as a drop),
      examine the Product for damage that can cause a safety concern. If necessary, return
      the Product to Fluke for evaluation.
    • The battery door must be closed and locked before you operate the Product.
    • Replace the batteries when the low battery indicator shows to prevent incorrect
      measurements.
    • Repair the Product before use if the battery leaks.
    • Be sure that the battery polarity is correct to prevent battery leakage.

                                                            Within a function, push to move forward
              For absolute versions of the gauge,           through options.
               push to set the barometric reference
               pressure.
             The Product records minimum and
             maximum pressure values and saves them
             in memory.
             Push 1X to show the maximum (MAX)
             value on the display.
             Push 2X to show the minimum (MIN) value
            on the display.                                 Within a function, push to move backward

               After 2 seconds, the display shows the
               live operation value again.
             To clear the MIN/MAX memory values,
             push and hold for 2 seconds until CLr

                                                             and go back to the Setup menu.
                                                             Within a function, push to set the option
            Toggles the backlight on/off.
                                                             and go back to the live view.
Basic Operation
Push  to turn on/off the Product. To maximize the life of the batteries, use the Auto Off feature. See
Table 4.
The analog bar graph at the bottom of the display shows the applied-pressure level relative to the full
range of the gauge.
                                                   Note
   If you record a Tare value, the pressure value that shows on the display is not the actual pressure
   applied to the gauge.
                                                                                                          5

Set Tare
Use to set a constant offset value to subtract from a pressure measurement.
                                                   Note
   If you record a Tare value, the pressure value that shows on the display is not the actual pressure
   applied to the gauge.
For example, if a tare is set at 30 psi and the measured pressure is 37 psi, 7 psi shows on the display. If
a tare is set at 30 psi and the measured pressure is 27 psi, -3 psi shows on the display.
The tare value is based on the pressure units and resolution selected. The tare value can be set to the
maximum range of the gauge.
For safety, the bar graph always shows the actual pressure based on the full range of the gauge
regardless of the tare position. Even when the pressure value shows “0”, the bar graph shows the actual
applied pressure.
Supervisory Mode
If needed, use Supervisory mode to lock/unlock functions to enable/disable changes to the functions. If
FUnC LOCK shows on the display, at least one function is locked. The password for Supervisory mode
is “101”. The password is set at the factory and cannot be changed.
To open Supervisory mode:
1. Push  .
   0 PWRD shows on the display.
2. Push  to put in the password.
   To move through the numbers in increments of 10, push and hold /. To move through the
   numbers in increments of 1, push /.
3. Push .
To lock/unlock a function:
1. Open Supervisory mode.
2. Push / to select UnLOC or LOC.
3. Push  to set the option.
Set Custom Unit/Scale
Use to set a factor to multiply a pressure measurement by to make a custom unit/scale.
Example: 40 psi is the equivalent of 1000 lbs of product in a tank. To show the product weight with a
100 psi gauge, set the factor to 25. 40 psi pressure shows as 1000 (40 x 25) on the display. The units
show as CUST.
                                                                                                         7
