accuracy and the largest display readout in the

industry of .66˝ high. Other industry-leading fea-

tures include twelve selectable engineering units,

seven languages, and password-protected disable

and calibration functions. With the range printed

on the keypad, the Ashcroft digital gauge meets

the ASME B

40.7 digital gauge specification.

UPDATE: this option allows for changing the rate
at which pressure is updated on the display
screen. The default rate measures pressure at the
maximum rate of 10* updates per second or 100
milli-seconds. Optional rates of measurement are
mea

sured in updates per second. The options are
10*, 5, 2 or 1 update of pressure measurement

CALIBRAT.:
Gauge Calibration: Both zero and span adjust-

ments are available. This gauge has been config­ured with a default password of ШШШШШ. This fac­tory password does not allow access to calibra­tion. To access the calibration mode, it is neces­sary to configure a user password. Once the user
password is configured, it will become the default
password

that allows access to gauge calibration.

KEYPAD FUNCTIONS

To access the factory default password:
Step 1: Press the CONFIG key until the word

CALIBRAT appears.

Step 2: Press the ENTER key.
Step 3: The letters/asterisks… PW***** appear.
Step 4: Press the CONFIG key. An Ø appears in

the first position.

Step 5: Press the ENTER key once.
Step 6: Press the CONFIG key until Ø appears. Ø

will appear in the second position.

Step 7: Press ENTER.
Step 8: Use this forma

t until all the asterisks are

replaced with Ø.

There now should be a total of five Ø’s on the
keyboard display. The zero in the fifth position
should be blinking.

Step 9: Press the ENTER key. You are now

prompted to SET PW (or set password).

Step 10: Press the ENTER key.
Step 11: Decide on a five number user password,

then follow the procedure above insert­ing a number in the flashing display until
all fiv

e numbers are inserted.

Step 12: A SAVE prompt will then appear. If the

selected user password is acceptable,
press ENTER. If the selected user pass­word is not acceptable press ZERO
CLEAR to refigure the user password.

After the password is configured, the default
factory password will be replaced with the user
password. Once configured, the factory password
is no longer accessible.

If an incorrect passw

ord is entered, the system
will display WRONG. Press the CONFIG key to
reenter the correct password.

Step 13: Press ENTER again to begin calibration.
Note: Calibration feature allows recalibration of

zero and span.

KEYPAD FUNCTIONS

Zero Calibration:
Step 14: Press the CONFIG key once and the word

CALIBRA appears. Press ENTER. (This
mode allows for 0 and full- scale adjust­ment of span.) The gauge will now dis­play 0.00. Ensure the gauge is not pres-

then press ENTER to zero the

gauge. Zero calibration is now complete.

Full Scale Calibration
Step 15: The gauge will now display full-scale

range (e.g. 100.00 psi). Pressurize

the
gauge to 100% of the range (which is
equal to the displayed value) utilizing a
pressure standard with accuracy four
times greater than the unit being calibrat-

ed.

Press ENTER. Full-scale calibration is

now complete.

Notes:

1. If the digital gauge under test is not pressurized

while in span adjustment of full-scale range, an
ERROR message will be displayed when the
ENTER button is pressed. If this occur

s, press
the ZERO CLEAR button on the keypad to return
to the previous screen.

2. ASME B40.7-1998, section 6.1.1.1 recommends
the working standard for the gauge being tested
is 4X better than the digital gauge under test.
This means the pressure standard measuring
the full-scale pressure being applied to the
gauge should have an accuracy four times
greater than the unit being spanned.

Zero SP (span):

This f

eature allows setting the % of span in which

the zero button will operate. Span is limited to pre­vent accidental tare of process pressures. Options
are 5%, 10% or DISAB (5% is the factory default
and means the unit can be rezeroed between ±5%
of span). If DISAB is selected, the zero button is
deactivated and no display change will occur when
the zero button is pushed.

KEYPAD FUNCTIONS

Step 1: Press the CONFIG key until the word ZERO

SP appears.

Step 2: Press ENTER.
Step 3: Enter user five digit password (PW). This is

the same password established to access
the CONFIG mode in the menu.

Step 4: Press the CONFIG key to select the

desired option.

Step 5: Press ENTER to finalize the selection.
Notes:

Selecting the DISAB feature does not disable the
CLEAR button on the keypad for the MAX/MIN
ture. If the DISAB feature is selected, pressing the
ZERO button on the keypad will cause the display to
read DISAB for two seconds. The gauge will then
revert back to the unit of measure of the gauge. The
DISAB feature disables the zero feature of the gauge.

Gauge Installation:
Pipe Mount – The Ashcroft digital test gauge comes standard with

a1⁄4 NPT connection. Good piping practices recommend using
teflon tape or a pipe sealant on the gauge threads. Utilize a7⁄16˝
wrench on the wrench flat of the gauge to tighten the gauge to the
process.

NEVER TIGHTEN GAUGE THREADS BY HOLDING THE BODY OF
THE GAUGE. DOING SO MAY DAMAGE THE GAUGE AND MAKE
THE GAUGE INOPERABLE.

Panel Mount – The lower connected Ashcroft digital test gauge is
available with an optional flange for panel mounting. Please refer to
illustration and dimensions below.

Battery Installation and Replacement:

The gauge comes standard with three AAA alkaline batteries installed.
For battery replacement use only one of the three types listed below:

• Energizer AAA alkaline, E92

• Energizer AAA alkaline, EN92 LR03 AM4 1.5V

• Duracell AAA alkaline, MN2400 LR03 1.5V
Do not mix ages or brands of batteries. Do not replace batteries in

hazardous areas.
Batteries have a life of approximately 1000 hours. Battery life is

dependent on gauge usage, backlite settings and power off settings.
When the display flashes LOW BAT, batteries should be replaced.

To replace the batteries:

1) Remove the single screw on the back of the gauge case.

2) Hold the keypad in the palm of hand.

3) Carefully remove the three batteries from the holder and replace
the
batteries. Use only AAA alkaline non-rechargeable batteries.
