When the unit has completed a successful Air Calibration, the analyzer is then ready for gas
testing. The unit will display the screen shown in
(Figure 7)
. Determine if you are Vapor
Sampling or Liquid Sampling and make sure the proper hose assembly is connected to
complete your required form of testing. Section
2.4 Vapor Sampling
and
2.5 Liquid Sampling
outline proper procedure for both forms of testing.
Connect the hose to the tank or system, open the valve if connecting to a tank, and then press
‘TEST’. The
YELLOW JACKET 68940
will display the screen shown in
(Figure 8)
. Before the
test is completed the screen in
(Figure 8a)
will appear to indicate the test is nearly complete.
2.4
Vapor Sampling
Vapor sampling is the most common method used for identifying refrigerants using the
YELLOW JACKET 68940
. It is a simple process requiring the operator to take these 4 steps:
1) Connect the Low Pressure Vapor Sampling Hose to the Low Side Vapor port
of the system or cylinder.
2) Open the low side valve of the cylinder and press
‘TEST’
(Figure 7)
.
3) When the test is complete, close the low side valve of the cylinder and
disconnect the hose from the cylinder.
4) Disconnect the hose from the
YELLOW JACKET 68940
for storage.
