1290 Strain Gage Input Indicator 17
B1. FULL SCALE READOUT
The display alternates between
F.S.U.
(Full Scale Value) and a numerical value from 10 to 99900.
Only the numerical value will be shown during modification., This value MUST be set equal to the
sensor full range, e.g. 10,000 PSI.
C. DISPLAY FILTER TIME CONSTANT
The display shows
F.T.C.
(Filter Time Constant) followed by:
.4
for 400 millisecond filter time constant
1
for 1 second filter time constant
2
for 2 second filter time constant
3
for 3 second filter time constant
4
for 4 second filter time constant
5
for 5 second filter time constant
D. INPUT INTERRUPT
The display shows
I.F.S.
(Input Fail Safe) followed by:
Hi
for up scale fail mode, or
Lo
for down scale fail mode.
E. SHUNT CALIBRATION
The display shows
S.C.
(Shunt Calibration) followed by:
On
for shunt calibration enabled, or
OFF
for shunt calibration disabled.
NOTE: Set Shunt Calibrations to
On
when using Dynisco transducers.
E1. SHUNT CALIBRATION VALUE
This step is skipped if the shunt calibration is
OFF
.
The display alternately shows
Shunt
and a numerical value from 40.0 to 100.0, but only the
numerical value will be shown during modification. This value corresponds to the percentage of the
Full Scale Value.
NOTE: When using Dynisco transducers, the Shunt Calibration value should be set to 80.0
F. EXTERNAL CONTACT function
The display shows
E.C.
(External Contact) followed by:
nr
to enable external contact for manual alarm reset, via rear terminals 7 and 8, or
Ho
to enable external contact for hold-on-value sampling.
F1. CONTACT STATUS
The display shows
C.S.
(Contact Status) followed by:
CL
if function selected above is performed with contact closed, or
OP
if function selected above is performed with contact open.
