been properly recorded on non-defective media. Fluke does not warrant that software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to
extend a greater or different warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke
authorized sales outlet or Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for importation costs of
repair/replacement parts when product purchased in one country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective
product which is returned to a Fluke authorized service center within the warranty period.
uke assumes no risk
for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke

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.

• 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

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 .
Pressure now shows in the chosen engineering units.

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.

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

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 low-
battery icon () shows on the top left of the display. To
replace the batteries, see the How to Change the
Batteries section.
Maintenance
