7.4 Temperature Calibration
7.4.1 The temperature channel was calibrated at the factory. It is a single point
calibration at 25°C. If needed, this calibration can be repeated as follows:
a) Disconnect the temperature sensor wires from terminals BK and YL on TB2.
b) Enter the Utility Menu, as described in 7.2.1.
c) Press MENU until the TEMPERATURE LED illuminates which is “Temperature
calibration” in the Utility Menu.
d) Place slide switch S41 in the ‘up’ (TEST) position.
e) Adjust the display to read 25.0°C. Press ENTER. The display will flash until
ENTER is pressed again to confirm entry.

g) Press RUN to go on line, or MENU to proceed to another Utility Menu item.
7.5 Temperature Output
7.5.1 The 0-5 Vdc and 0-1 mA outputs jointly may be programmed to track the
temperature of the process. From the factory the outputs have a linear range
corresponding to 0 to 100°C (32 to 212°F). Suppose you wish the output to span
10 to 45°C. Proceed as follows:
a) Enter the Utility Menu as described in 7.2.1.
b) Press MENU until the OUTPUT HIGH LED illuminates, which is “Temperature
output, 100% point” in the Utility Menu (See table in 7.2.2). Use the arrow keys
to make the display read 45.0. Press ENTER. The display will flash until
ENTER is pressed again to confirm entry.
c) Press CALL and the OUTPUT LOW LED will illuminate, which is “Temperature
output, 0% point” in the Utility Menu (See table in 7.2.2). Use the arrow keys to
show 10.0 on the display. Press ENTER twice as above.
