Application Parameters
P214 4 mA TRIM
Use this feature (in combination with 20 mA Trim) if the device connected to the
mA output displayed is out of calibration, yet device recalibration is impractical.
Adjust this value as required to make the device connected indicate 4.000 mA
when this parameter is accessed. Use of this feature does not affect the mA
Value / Transducer (P203) value displayed.
values: -1.00 to 1.000
P215 20 mA TRIM
Use this feature (in combination with 4 mA Trim) if the device connected to the
mA output displayed is out of calibration, yet device recalibration is impractical.
Adjust this value as required to make the device connected indicate 20.00 mA
when this parameter is accessed. Use of this feature does not affect the mA
Value / Transducer (P203) value displayed.
values: -1.00 to 1.000
P219 mA FAILSAFE
Use this feature if mA output failsafe operation, independent from the Failsafe
Material Level (P071) is desired.
To select an independent mA Failsafe option value:
1. Press
to display the Auxiliary Function symbol.
2. Press or
to scroll access the failsafe options.
3. Press
with the desired option displayed.
values: "OFF" to have the mA output respond to the Failsafe
Material Level (P701) (F).
"HOLd" to hold the output at the "last known" value until
normal operation resumes.
"LO" to produce the "Empty" mA output immediately on
Failsafe Timer (P070) expiry.
"HI" to produce the "Span" mA output immediately on
Failsafe Timer (P070) expiry.
Alternatively, to produce an immediate mA output at a specific value, enter
the value required.
values: 0.000 to 22.00
