default, but it is user-modifiable.
Use the
s
or
t
buttons to set the left-
most digit to 3.
Press and release the Power button to
index to the next position.
The 3 will remain, and the second posi-
tion will be blinking.
Use the
s
or
t
buttons to select 5.
Press and release the Power button
to index to the next position. 3 5 will

remain, and the fourth position will be
blinking.
Use the
s
or
t
buttons to select 0.
Press and release the Power button to
proceed with configuration.
Note: If an incorrect passcode is entered,
the gauge will return to the start of the
passcode entry sequence.
Press and release the Memory button
until Max or Min is displayed.
Depending on your configuration the
gauge may save both Max and Min, or
either Max or Min.
The gauge may be left in the maximum
or minimum display mode if desired. The
reading will be continuously displayed,
stored and updated.
The center power button may be pressed
at any time to return to the normal dis-
play mode.
Min/Max Memory
The Min/Max readings are captured at the rate of 3 times per
second. If a brief pressure deviation occurs, it may not be cap-
tured. The readings are captured any time the gauge is on, but
not while in the configuration or calibration mode.
The gauge can be configured to capture and display:
O
Both maximum and minimum values (factory default)
O
The maximum value only
O
The minimum value only
O
Saved Min/Max values when the gauge powers down
Min/Max Memory Retention
The upper display indicates
clr
and the
lower display will indicate the current
setting for min/max memory. Press:
Power button: Keep setting
s
button: Select AUTO and automatically
clear the maximum and/or minimum
readings when the gauge is shuts off.
t
button: Select MAN and retain the
maximum and/or minimum readings in
memory after the gauge is shut off. The
readings can be cleared manually.
Press and release the power button to
save your selection and move to the next

GAUGE CONFIGURATION
Enter Configuration Mode
The gauge uses a 4 digit passcode
to enter the configuration mode. This
is to prevent unauthorized changing of
settings.
With the gauge off, press and hold the
s
button.
Then press the center power button.
Release all buttons when the display
indicates
CFG
. The gauge firmware ver-
sion is also displayed.
The gauge then goes through the normal
power up sequence.
The display prompts for entry of the
configuration passcode (CFGPC), with the
first underscore blinking.
Note: The gauge will automatically revert
to normal operation if no buttons are
pressed for approximately 15 seconds.
To cancel and return to normal operation,
press and release the power button with-
out entering any passcode characters.

Engineering Unit Selection
Note: For vacuum/pressure gauges or
compound gauges the choice of CMPND
(inHg/psi) or -/+EU (±Engineering Units)
will appear. Select -/+EU to change to
other engineering units.
Engineering units are shown in the lower
display.
Use the
s
and
t
buttons to navigate
through the list of engineering units.
Available engineering units depend on
the sensor range.

Auto Shutoff Time Selection
The auto shutoff time is displayed on
the upper display. The lower display
will indicate AST M for minutes or AST
H for hours.
Use the
s
and
t
buttons to select 0
(manual shutoff), 1, 2, 5, 10, 15, 20, or
30 minutes, or 1, 2, 4, or 8 hours.
A setting of zero disables the auto shutoff
timer. Use the Power button to shut the
gauge off.
When the desired time is displayed press
and release the Power button to save
your selection and move to the next
parameter.
Clear a Memory Location
For many applications it may be desir-
able to bring the system up to normal
pressure and then clear the minimum or
maximum value.
Press and release the Memory button
until the value to be cleared is displayed.
Press and hold the Zero/Clear button.
Release the button when
clr
is dis-
played. The reading for the indicated
memory location will be cleared.
With a gauge reference models if no
pressure is applied, the value will return
to zero.
If pressure is applied the new pressure
reading will be stored in memory.
Absolute reference models will store the
current atmospheric pressure reading if
the gauge port is open to atmosphere.
Press and release the Power button to
exit the memory mode and return to live
pressure readings.

ERROR INDICATIONS
Zero Error
Attempting to zero gauge reference mod-
els with more than approx. 3% of full-
scale pressure or vacuum applied will
result in an error zero condition. The
display will indicate
Err 0
.
If your intent was to zero the gauge, make sure to remove all
pressure from the gauge port.
Press the power button to reset the error.
Excessive Vacuum
Excessive vacuum applied to a pressure-
only gauge will display as
-Err
until the
vacuum is released. Note: A pressure-
only gauge will be damaged by excessive
vacuum.
Excessive Pressure
If 112.5% over range pressure is applied,
an out-of-range indication of
1 – – –
or
1.–.–.–
will be displayed depending on
model. Use gauge within the appropriate
pressure range to prevent damage.
