6.5.3. TS-Span Procedure
1. 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
the
▲▼ and ◄► buttons to enter an applied value that exactly
equals the thermometer reading.
NOTE: The calibration range is from 175 to 625 °F (80 to
330 °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.

2. Wait until the measured reading stabilizes, and then press ENT to
calibrate the TS-Span Measured value to that of the applied value; after

The use of an electronic thermocouple simulator is the preferred method of
producing the desired calibration temperatures. Alternatively, containers of ice
