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.

XWWarning

To prevent injury, 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.

To prevent possible electrical shock, fire, or
personal injury:

• Read all safety Information before you

use the Product.

• Use the Product only as specified, or the

protection supplied by the Product can
be compromised.

• Do not use the Product around explosive

gas, vapor, or in damp or wet
environments.

• Do not use and disable the Product if it

is damaged.

• Remove the batteries if the Product is

not used for an extended period of time,
or if stored in temperatures above 50 °C.
If the batteries are not removed, battery
leakage can damage the Product.

Safety Information

• Replace the batteries when the low

battery indicator shows to prevent
incorrect measurements.

• The battery door must be closed and

locked before you operate the Product.

WCaution

To prevent possible damage to Product or to
equipment under test:

• The display reads “OL” when the

pressure source is above the Product
range limit. The pressure source must
immediately be removed.

• Do not apply more than the maximum

torque specified. Maximum torque
specified is 20 Nm = 15 ft-lb.

Special Conditions for Safe Use

Misuse

If the Product is exposed to overpressure or sudden
physical shock (such as being dropped) examine it for
damage that can cause a safety issue. If necessary, send
the Product for examination to Fluke. Refer to the How to
Contact Fluke Calibration section.

WWarning

To prevent possible fire, or personal injury:

• Do not use the Product with flammable

substances.

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 shown
is not the actual pressure applied.

How to Setup the Product

Before you use the product, it is necessary to configure it
for your application. Push  to go to the Setup menu.

Each time  is pushed, the display goes to the
subsequent function. Push  or  to change the
parameter value. When a parameter is set, push  to
exit the configuration menu or  to move to the next
parameter.

Engineering Units

The Product’s default engineering unit shows psi. To
change this, push  and  to move through the
standard engineering units plus one custom unit/scale.
When the necessary unit shows, push  or .

engineering units. See the Supervisory Mode section for
instructions to set up custom units.

Set Auto Off

Auto Off can be set in 1 minute increments from 1 to 30
minutes or you can turn off the function for continuous
Product operation. The Product is configured for 30
minutes. Push  and  to set the necessary interval.
The “off” position is at the low end of the selections, less
than 1 minute.

Show Battery Voltage

Actual battery voltage and a percent-of-life bargraph
show the battery charge. No adjustments are made in this
parameter.

Display Actual Temperature

The Product is temperature compensated This parameter
shows the temperature measured by the internal sensor.
Push  or  to show degrees F or C.

Set Damping

Selections are “on”  and “off” . Damping smooths
readings from pulsating pressure sources.

Set Sample Rate

This function finds how many times pressure is sampled
and the display is updated. Selections are 0.5, 1, 3, and
10 samples/second. Note that 10/second gives the fastest
response time.

Set Tare

Use this function to set a constant offset value that is then
subtracted from the measured pressure. For example, if a
tare is set at 30 psi, and the measured pressure is 37 psi,
7 psi is shown.

A pressure of 27 psi is shown as -3 psi.

Push  and  to set the tare value. The value is in
relation to the engineering units and resolution selected
for display. Tare value can be set to the maximum range
of the gauge.

For safety, the bar graph always shows the actual
pressure in relation to the full range of the gauge
regardless of the tare position. This is done to make sure
that with a “0” reading pressure is being applied to the
gauge.

Function Lock

When set, access to each of the settable parameters
above can be turned “off” to prevent unauthorized
configuration changes. This is done with password
protection in Supervisory Mode. Push  to access
Supervisory Mode or  to go back to normal operation.

Supervisory Mode

If necessary, each user-configurable parameter can be
edited when you receive the Product. Some parameters
are locked and must be unlocked to configure them. Use
Supervisory mode to do this.

When you are in the Configure menu, and FUnC LOCK is
shown, it means that there are locked parameters.

To disable function lock:

1. Push  . 0 PWRD is then shown.

2. The password “101” is required to unlock

Supervisory mode. Push  to put in the password
entry. Hold  or  down to move faster through the
selections by a factor of 10. When you stop the
counter, push  and  again to move forward or
backward by a factor of 1. The password is factory
set and cannot be changed.

3. Push .

From this point each parameter can be locked or
unlocked. Push  and  to select UnLOC or LOC for

each parameter. To move to the subsequent parameter,
push .

You can access, lock, or unlock these functions:

• Zero function (enable/disable)

• Set pressure units (enable/disable)

• Auto shutdown adjustment (enable/disable)

• Damping settings (enable/disable)

• Sample rate setting (enable/disable)

• Tare setting (enable/disable)

• Custom engineering units (set scale factor)

When a function is locked, it cannot be accessed or
changed from its current condition until you go to
Supervisory Mode and unlock it.

Battery Life

How to Set a Custom Engineering Unit or Scale

The last menu selection in Supervisory Mode is
SET FACTR. You can set a multiplier factor from 0.001 to
100 to make a custom scale. The set factor is multiplied
by the psi measured and the result is shown.

Example: 40 psi is the equivalent of 1000 lbs of product in
a tank. It is necessary to show the product weight with a
100 psi gauge. If you set a factor of 25, 40 psi pressure
shows as 1000 (40 x 25). The engineering unit shown is
Cust (custom).

Battery Life

Battery life is approximately 75 hours of operation with
the backlight off. When the battery voltage is low, the low­battery icon () shows on the top left of the display. To
replace the batteries, see the How to Change the
Batteries section.

Maintenance

How to Clean the Product

Clean the Product with a soft cloth dampened with water
or water and weak soap.

WCaution

To prevent possible damage to the Product,
do not use solvents or abrasive cleansers.

WCaution

For safe operation and maintenance of the
product:

• Repair the Product before use if the

battery leaks.

• Remove batteries to prevent battery

leakage and damage to the Product if it
is not used for an extended period.

• Be sure that the battery polarity is

correct to prevent battery leakage.
