What does it mean when the red
backlight flashes?
▪
The flashing red backlight indicates an error
condition.
▪
Possible error conditions are:
▫
Pressure has exceeded the stated upper
limit of the sensor(s).
▫
Pressure has fallen below the stated lower
limit of the sensor(s).
▪
The red backlight overrides the white backlight.
FAQs
What does the Zero (Ø) key do?
Home
▪
If the sensor is within a tolerance band around
zero, press and hold the
Zero
key to zero the
pressure measurement and to reset the Min
and Max measurements.
▪
Note
: The tolerance band is approximately ± 1
% of the Full Scale pressure value of the sensor.
▪
Absolute sensors have additional functionality.
In Min or Max mode
▪
Press and hold the
Zero
key to reset the Min
and Max measurement. However, this does not
zero the pressure measurement.
In Tare mode
▪
When the Tare is off (T.OFF), press and hold
the
Zero
key to turn on Tare (T.ON) and to
set the Tare value at the current p ressure
measurement.

Why are the available units different
between a 15 psi and 3 000 psi sensor?
If a given measurement unit cannot display
the correct number of digits, the calibrator
automatically advances to the next displayable unit.
