Calibration,” p. 27.
b. To complete zero gas calibration without continuing
to the span gas calibration, select Done,
and go to
the next step.
c. To return to the Results screen,
select Back.
5. On the bottom of the device, install the pin in the
calibration port.

Span Gas Calibration
Note: To prevent zero-gas contamination, Trane
recommends using different regulators to do zero
gas calibration and span gas calibration.
1. Close the cylinder valve.
2. If applicable, remove the zero-gas cylinder or zero-gas
scrub
ber tubing from the calibration port.
3. On the Sp
an Gas Calibration screen, select the
a
pplicable span gas.

Gas screen: six user-selected gases and one
universal gas (Synthetic R-134A).
4. On the gas cylinder label, find the concentration for the
gas.
5. On the Set
Span Gas Value screen, to adjust the
concentration value to the value on the gas cylinder
label, either use the and buttons to increase or
decrease the value in 1 ppm increments, or select the
value field and use
the alphanumeric keypad pop-up to
enter the value. Select to accept the value.
6. To do the calibration with synthetic R-134A, select the
check box.
7. Select Next.
Note: The concentration value can be set between 50 and
500 ppm.
8. Attach the span-gas cyl
ind
er tubing to the calibration
