3.2.9 Loop Break Time/Field Calibration (continued)
Reading Offset Adjust allows 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).
Reading Adjust
is adjustable between -1999 to 9999. For Temperature Reading only,

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.
