6.6.3. TA-Span Procedure

1. Set thermocouple simulator to 212 °F (100 °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

thermometer reading.

NOTE: The calibration range is from 194 to 230 °F (90 to

110

°C). An attempt to calibrate outside this range will

cause the message “Bad Calibration Wrong CAL Entry” to

appear in the following step.

2. Wait until the measured reading stabilizes, and then press ENT to

calibrate the TA-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.

6.7. CO

LOW

Sensor Calibration

NOTE: The CO

LOW

sensor also measures H

for the purpose of

compensating the CO reading for the presence of H

in the gas

sample. This procedure first spans the CO

LOW

sensor and,

optionally, spans the H

part of the sensor to known gas levels.

The user has the option to perform a CO only calibration or a CO/H

calibration

using the PCA

3 soft keys.
