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
SETPOINT DEVIATION ENABLE/DISABLE SUBMENU:
Press d 13) Display advances to Setpoint Deviation ENBL Enable or DSBL Disable Submenu and flashes the previous selection.
Press b 14) Scroll through the available selections: ENBL or DSBL.
Press d 15) Display shows STRD stored message momentarily and then advances to CAL1° Menu.
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:
CAUTION: Do not perform the following steps until you fully understand this entire section.
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
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.
