Alternatively: Submerge probe tip into an ice-water bath with a ther-
mometer, wait several minutes, and then use the and buttons
to enter an Applied value that exactly equals the thermometer read-
ing.

5. Wait until the Measured reading stabilizes, and then press ENTER
to calibrate the TS-Zero Measured value to that of the Applied
value; after which the message “Good Calibration” should briefly
appear followed by the CALIBRATE TS-SPAN screen.
TS-Span Procedure:
6. Set thermocouple simulator to 572
°F (300 °C), and then use the and
buttons to enter an Applied value that
exactly equals the setting of the simulator.
Alternatively: Submerge probe tip into a container of boiling water
with a thermometer, wait several minutes, and then use the and
buttons to enter an Applied value that exactly equals the ther-
mometer reading.
Thecalibrationrangeisfrom175to625°F(80to330°C).Anat-
tempt to calibrate outside this range will cause the message “Applied
ValueHigh”(orLow)toappearatthebottomofthescreen.
7. Wait until the Measured reading stabilizes, and then press ENTER to
calibrate the TS-Span Measured value to that of the Applied value;
after which the message “Good Calibration” should briefly appear fol-
lowed by the CALIBRATION LIST screen being re-displayed.
5.6 T-Air Calibration
This procedure first zeros and then spans the ambient-temperature chan-
nel to known temperature values.
The use of an electronic thermocouple simulator is the preferred method of
producing the desired calibration temperatures. Alternatively, ice and boil-
ing water baths can be used.
