Selecting the Units
Select the units of pressure using the

key.
For -U1 models Pressing the
UNIT
does not change the units.
For -U2 models Pressing the
UNIT
switches the units in the order kPa,

Note
• The factory default units setting is kPa.
• Units cannot be switched when in % display or %ERROR display modes.
During normal measurement units are displayed as shown in the left column below. However,
when in % display mode they appear as shown in the right column, and only the units for the
current input pressure being % displayed are shown.
The same is true for the current and voltage display of the DMM function.

Selecting the Number of Display Digits
Measured pressure values can be displayed with the lowest digit masked. This
is useful when the lowest digit flickers and is difficult to read.
Pressing
DIGITS
causes the lowest digit to be masked, and the display to show
4-1/2 digits. Pressing
DIGITS
a second time unmasks the lowest digit, and
causes the display to show 5-1/2 digits.
However with 700 kPa models (767355, 767365, 767373 and 767385),
measured values are displayed only in 4-1/2 digits without the mask, or 3-1/2
digits with the mask.
Note
This also applies to % display of DMM (%ERROR display) if % display or %ERROR display
mode is active.
Relative Display
When the RELATIVE key is pressed the difference between a reference
pressure and the pressure being measured is displayed.
1.
Input the pressure to be used as the reference.
2.
Press the
RELATIVE
.
3.
RELATIVE is displayed as shown next page.
4.
To cancel relative display, press the
RELATIVE
. RELATIVE disappears from the
screen.
Note
While % or %ERROR display is active, relative display is inoperable even if the RELATIVE
key is pressed.
