From measurement mode:
1.
Enter Advanced set-up mode.
Push the ENTER key. Press the
▲
key to scroll to security code “22”.
Push the ENTER key again.
2.
Press the
▲
and

keys
to scroll
until the upper display shows tc.
3.
Press the ENTER key
until the
lower display shows P.tc and
the upper display shows the
temperature coefficient in a %.
See bold figure at right
4.
Press the
▲
and

keys
to choose
your process temperature coefficient.
You can select a value from 0.00 to
10.00%
5.
Press the ENTER key
to confirm
your selection.

Proceed to step 3 of section 6.2.3, or
press the
▲

keys together to
return to measurement mode.
6.2.2 Setting the process temperature coefficient
If the temperature compensation curve type “Pur” is set in 6.2.1, the parameters listed in 6.2.2
are blanked out. You will automatically return to Advanced Set-up mode.
This mode lets you input your solution’s true process temperature correction for high-
er accuracy. The controller will be set at 2.10% per °C standard, but you can adjust the
value from 0.00 to 10.00% per °C.
To calculate your solution’s temperature coefficient, see Appendix 2 on page 64.

6.2.3 Setting the calibration temperature coefficient
If the temperature compensation curve type “Pur” is set in 6.2.1, the parameters listed in 6.2.3
are blanked out. You will automatically return to Advanced Set-up mode.
This mode lets you input your solution’s true calibration temperature correction for
higher accuracy. Adjust this value if the temperature coefficient of the calibration solu-
tion is different from that of the process solution; otherwise, leave the calibration tem-
perature coefficient at the same value as the process temperature coefficient. The con-
troller will be set at 2.10% per °C standard, but you can adjust the value from 0.00 to
10.00% per °C.
To calculate your solution’s temperature coefficient, see Appendix 2 on page 64.
