2.3 System Operation
See below for pictures.
Insert one of the thermocouples
(3
,
Figure 1
)
into the corresponding input on the
temperature controller; the second is simply a spare. It is unnecessary to plug
the second thermocouple into anything. Connect the calibration gas line
(2)
and
the sample line
(1)
. Plug in the temperature controller and the heated sample
line
(4)
, as well as any other equipment (120V). Select the desired temperature.
Allow 10-15 minutes for the system to warm up then begin sampling.
CAUTION!!
–
If the light on the temperature controller does not blink when it
gets near the target temperature, overheating is very likely! The most likely
cause is a bad relay in the temperature controller.
NOTE
–
In the event of an overload, the circuit breaker on the temperature
controlling device will pop out. Simply push it in to reset.
