3.2.9 Loop Break Time/Field Calibration (continued)
Reading Offset Adjust
(C.J.) allow the user to fine tune a minor error of the transducer,
however some applications may require a large offset adjust. (Displayed Process Value
= Measured Process Value ± R.ADJ). R.ADJ is adjustable between -1999 to 9999.

Setpoint Deviation
Submenu, if “enabled”, allows changes to Setpoint 1 to be made
automatically to Setpoint 2. This mode is very helpful if the Process Value changes often.
In Setpoint Deviation Mode, set SP2 a certain number of degrees or counts away from
SP1 - this relation remains fixed when SP1 is changed. For instance: Setting SP1=200
and SP2=20 and enabling
SP.DV
means that the absolute value of SP2=220. Moving
SP1 to 300, the absolute value of SP2 becomes 320.
THERMOCOUPLE FIELD CALIBRATION SUBMENU:
RTD and Process are perfectly calibrated. This section is applicable to
Thermocouple (TC) calibration
only
.
Be sure that the TC being used to calibrate the meter is of the type
selected in the TC submenu. Place the TC in an ice-bath (or other
0°C / 32°F
environment). In ambient temperature conditions: connect the
TC to the meter, apply power to the meter.
CAUTION:
Do not proceed with TC calibration unless the above
conditions have been in effect for at least one hour.
