6.5.3. TS-Span Procedure

1. Set thermocouple simulator to 300 °C (572 °F), and then use the ▲▼
and ◄► buttons to enter an applied value that exactly equals the
setting of the simulator.
Alternatively:
water with a thermometer, wait several minutes, and then use
the ▲▼ and ◄► buttons to enter an applied value that exactly
equals the thermometer reading.
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
which the message "Good Calibration" should briefly appear followed by
the CALIBRATION LIST screen being re-displayed.

6.6. T-Air Calibration

This procedure first zeros and then spans the ambient temperature channel 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.

6.6.1. Material Required

Thermocouple Simulator (K-type)

6.6.2. TA-Zero Procedure

1. Set thermocouple simulator to room temperature and plug its output into
the T-AIR connector located at the bottom of the analyzer.

NOTE: The calibration range is from 80 to 330 °C (175 to
625 °F). An attempt to calibrate outside this range will
cause the message "Applied Value High" (or Low) to
appear at the bottom of the screen.
