• When performing a high calibration, make sure to select the correct calibration gas and
Caution:
confirm the expiration date before using.
• Never connect the sample line directly to a high pressure gas source (greater than
150 cmH
Note:
Complete a low calibration (see Low Calibration section) prior to completing the high calibration.

INOcal calibration gas kit sample tubing
When using the calibration tubing kit
(P/N 50239), which is supplied with the INOcal
regulator kit (P/N 10090), ensure that the beige
pressure relief valve supplied with the tubing is
installed and oriented as indicated in Figure 6-2.
An incorrectly installed one-
Caution:
way valve can lead to over-
pressurization of the sampling
system. A leak in the calibration
tubing kit (P/N 50239) attached to
the calibration cylinder regulator
can result in displayed NO
values greater than the set dose
value after passing a low and
high calibration successfully. This
can be caused by aging of the
calibration tubing. The calibration
tubing kit should be replaced under
the following circumstances:
• The tubing is discolored or stiff.
• There is a crack or break in the
tubing.
1. Remove cylinder cap and inspect for damaged
threads and contaminants.
2. Check seal on regulator. Verify it is correctly in
place and undamaged.
3. Attach regulator to cylinder (Turn regulator nut
counter-clockwise to tighten).
4. NOTE: Tubing adapter will be required if
regulator outlet diameter measures 0.24 in.
(6.10 mm).
5. Attach tubing kit to regulator outlet.
NOTE: Confirm water trap bottle, water separator
cartridge and patient gas sample line are in place.
