3.2
Startup of the Ozone Calibration Source
™
To operate the Ozone Calibration Source
™, connect it to an external power source
and turn the instrument on by flipping the front panel switch. The instrument requires
a 12 V DC source which can be supplied by: 1) the 110-220 V AC power adapter (2.5
amp or higher), 2) a cigarette lighter adapter plugged into a 12 V DC source such as
found in an automobile or many light aircraft, or 3) a 12 V battery. The source must
be very close to 12 V because of the power requirements of the instrument’s pump.
When using a battery, be certain to attach the positive (red) and negative (black) wires
correctly. A circuit breaker and diode are installed on the circuit board in case of an
electrical short or incorrect battery attachment. If activated, the breaker will reset itself
after a few minutes.
Once turned on, the instrument will briefly display the version number of the software
installed on the microprocessor. The instrument will then display
Warming up …
delT = -xx.xx
where
delT
is the deviation of the temperature of the photolysis chamber from the set
point of 315 K (42°C). As the chamber warms up, the temperature deviation will be
continuously displayed. During the warmup period, the photolysis lamp and the pump
are turned off and the internal 3-way valve is set to divert sample air to the output of
the Model 306.
Warmup will take approximately 15-20 minutes. Once
delT
is within 1
°
C of the set
point, the display will read:
