Figure 2-1. Function tests.
(1) You test each tube at three different pressures using different function
tests. In order to get accurate readings, you must use the correct gas when performing
a particular test.
To test the N2O flow tube:
(a) Turn on the O2 gas to a minimum of 30 psi.
(b) Turn on the N2O gas.
Input test 33 on the RT200.
(d) Record readings on the RT200 when the N2O flow meter gauge
reads 1 lpm and 4 lpm.
(e) Input test 37 on the RT200.
Record the reading on the RT200 when the N2O flow meter gauge
reads 7 lpm.
To test the O2 flow tube:
(a) Turn off the N2O gas and turn on the O2 gas.
(b) Input test 31 on the RT200.
(c) Record the readings on the RT200 when the O2 flow meter gauge
is at 1 lpm and at 4 lpm.
