Step T-STACK Calibration Procedure
6 Set thermocouple simulator to 572° F (300° C), and then use the UP (),
DOWN (), LEFT (), and RIGHT () arrow 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 arrow buttons to enter
an Applied value that exactly equals the thermometer reading.
NOTE: The calibration range is from 175 to 625° F (79 to
329° C). An attempt 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 followed by the
CALIBRATION screen being re-displayed.
5.7. T-Air Calibration
This procedure first zeros and then spans T-AIR temperature to known
temperature values.
The use of an electronic thermocouple simulator is the preferred method of
producing the desired calibration temperatures. Alternatively, containers of ice
water and boiling water can be used.
