11.5 Out of Range Display
(1) Range Over displa y
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.
(2) Span Over display
When the user has adjusted the span of the device this case 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.
(3) 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.
