(b) How to execute sensor two-point correction (when using the program)
Follow the instructions below.
*1 Enter the value using devices such as a thermocouple, platinum resistance thermometer, and standard DC voltage
generator, or based on a general resistance value.
*2 When the latch is completed, the temperature process value (PV) is stored in CH Sensor two-point correction offset
value (measured value) (Un\G544, Un\G576, Un\G608, Un\G640). ( Page 142, Section 3.4.2 (58))
*3 When the latch is completed, the temperature process value (PV) is stored in CH Sensor two-point correction gain
value (measured value) (Un\G546, Un\G578, Un\G610, Un\G642). ( Page 143, Section 3.4.2 (60))
Set Sensor correction function selection
(Un\G785) to Sensor two-point correction (1
H
).
Turn on Setting change instruction (YnB).
Set a temperature process value (PV) in CH
Sensor two-point correction gain value
(corrected value) (Un\G547, Un\G579, Un\G611,
Un\G643).
Check that Setting change completion flag
(XnB) is on.
Turn off Setting change instruction (YnB).
Enter a correction offset value.*
1
Enter a correction gain value.*
1
Set a temperature process value (PV) in CH
Sensor two-point correction offset value
(corrected value) (Un\G545, Un\G577, Un\G609,
Un\G641).
Set CH Sensor two-point correction offset
latch request (Un\G548, Un\G580, Un\G612,
Un\G644) to Latch request (1).
Check that CH Sensor two-point correction
offset latch completion (Un\G549, Un\G581,
Un\G613, Un\G645) is Latch completed (1).
*2
Set CH Sensor two-point correction offset
latch request (Un\G548, Un\G580, Un\G612,
Un\G644) to No request (0).
Set CH Sensor two-point correction gain
latch request (Un\G550, Un\G582, Un\G614,
Un\G646) to Latch request (1).
Check that CH Sensor two-point correction
gain latch completion (Un\G551, Un\G583,
Un\G615, Un\G647) is Latch completed (1).
*3
Set CH Sensor two-point correction gain
latch request (Un\G550, Un\G582, Un\G614,
Un\G646) to No request (0).
1
Set CH Stop mode setting (Un\G33, Un\G65,
Un\G97, Un\G129) to Monitor (1).
Setting start
Switch the module to the setting mode (turn off
Setting/operation mode instruction (Yn1)).
2
End
Switch the module to the operation mode (turn
on Setting/operation mode instruction (Yn1)).
Is the ERR.LED off?
Go back to 1 or 2.
