Minimum / Maximum Reset
The Minimum / Maximum values can be reset when in either Mini-
mum / Maximum display or Measurement Mode by holding the
DOWN # button for more than three seconds, “cLr” will appear on
the display for two seconds and the Minimum and Maximum values
will be removed.
Note: Values are maintained even if unit is powered OFF.

• When first using unit be sure to Reset values to clear values in

memory from the factory calibration process.

• Values are captured starting one minute after Reset, thus if unit is

powered OFF during the one minute the values during that period
will not be kept in memory.

A.

Out of Range Display
In the Measurement Mode, if the pressure is below –15% F.S.
(URL) “-FFF” will be displayed, and if it is more than 115%F.S.,
“FFF” will be displayed.

B.

Out of Span Display
When the user has adjusted the span of the device this will apply.
The display range in each display mode is –5 to 105%F.S. of the
display span. When this range is exceeded, the value of –5%F.S. or
105%F.S. will be held (depending upon whether unit is below or
above the span values) in a blinking state.

C.

Analog Output
The analog output is linked with the display and is at 3.2mA when
the display span is at or exceeded –5%F.S. and at 20.8mA when
the display span is at or greater than 105%F.S. .

Example: Out of Range Display
Pressure display (Pressure range: 0-100 psi)
Pressure display span: 0-50 psi
Span point: 1.000
