7.2 Temperature calibration (ATC mode only)
1) Enter Advanced Set-up mode. Push the ENTER key and scroll to
Advanced Set-up security code “22”. Push the ENTER key again.
2) Press the ∆ or ∇ keys to scroll through the sub-menus until the
display shows “Set
o
C”. Press the ENTER key.
3) Press the ∆ or ∇ keys to scroll until the upper display shows “ATC”,
and the lower display shows “on”. Default setting is “ATC on”.
4) Press the ENTER key. In this mode, the ATC probe can be
calibrated. The upper display indicates the current temperature offset.
The current measured temperature is shown in the lower display.
5) Compare the current measured temperature on the controller display
to a thermometer known to be accurate. Note down the correct
temperature value.
6) Press the ∆ or ∇ keys to scroll the lower display to match the
correct value. The upper display will now show the offset value. You
can offset temperature up to ± 10
o
C.
7) Press the ENTER key to confirm your selection.
8) Continue with additional Advanced Set-up procedures, or return to
the Measurement mode by pressing the ∆ and ∇ keys (escape)
simultaneously.
7.2.1 Setting manual temperature compensation
Note: This parameter is unavailable if ATC is selected.
For manual temperature compensation, two different temperatures:
process and calibration can be input independently. Example: setting a
calibration temperature of 25
o
C lets you calibrate using standard
buffer solutions at 25
o
C, even if process temperature is different.
1) Enter Advanced set-up mode. Push ENTER key and scroll to
Advanced Set-up security code “22”. Push ENTER key and
Press ∆ or ∇ keys to scroll till display shows “Set oC”. Press
ENTER.
2) Pressing the ∆ or ∇ keys keys toggle between ATC ‘on’ or ‘off’
(default setting is ATC on). Select “ATC off”.
3) Press ENTER key. Upper display shows current process
temperature and lower display shows “P.
o
C” to indicate process
temperature.
4) Press ∆ or ∇ keys to adjust process temperature value from –
9.9 to 125
o
C.
5) Press ENTER key. Upper display shows current calibration
temperature and lower display shows “C.
o
C” to indicate calibration temperature.
6) Press ∆ or ∇ keys to adjust calibration temperature value, –9.9 to 125
o
C. Press ENTER key.
