Custom Units of Measure

Allows a user to define a custom unit of meas-
ure, user must enter the full scale value of the
desired reading, which can be done as follows.

1) In Menu Mode press 

select

“CUSTU” press 

 

|

|

.

2) Select decimal point location:

The alphanumeric display shall show “SELDP”

The first screen to appear will show all digits
lit up as “5” and the rightmost decimal point
will blink (5 5 5 5.5) unless the custom units
feature had been used previously. If it had
been used, the digits  and decimal point po-
sition shall correspond to the last values set.
Use the 

keys to move the deci-

mal point to the left or the right.  Once the
decimal point is in the desired position,
press 

 

|

|

to lock it in place. When the

key is released the display reads “DIGIT”.

3) Choose full scale value:

The alpha numeric display shall show “DIGIT”.

The next screen will continue to show all
digits as “5”, with the leftmost digit blinking
and the decimal point fixed in the previously
chosen position.  However, if the custom
units feature has been used previously, then
the digits shall correspond to the last value.
The decimal point remains at the location
chosen in step 1.  Press 

to

change the value of the digit between 0-9.

Once the desired value is displayed, press
the 

 

|

|

button to lock it in place. Now

the next digit to the right will begin blinking.
Repeat this procedure for all 5 digits. When
the 

 

|

|

is pressed and released with the

fifth digit flashing, the gauge will briefly dis-
play “DONE” then return to measurement
mode and display “CUSTU” along with the
numeric readings to signify that the feature
is use.  

The user can optionally exit at any point
 before the enter key is pressed with  

MENU

. If the user exits the menu by a

MENU

before completing step 2 or

there is a menu timeout, then whatever the
user entered will be lost. 

Note:

The custom units feature is not avail-

able with compound pressure ranges.

Note:

The bar graph uses the factory default

setting when custom units are used.

Note:

The magnitude of the value entered

when using the custom units feature can
significantly increase the noise on the dis-
play, which can affect the zero and tare
functions as well as the stability of the pres-
sure reading displayed. If required, consult
factory for recommended limitations on full
scale input.
