Model 306 Ozone Calibration Source Manual Rev. G-1
16
As noted in the table above, the instrument must be put in
hibernate
mode (or power
cycled) after changing the scheduler hour with the
set hr
command. Otherwise, the
step program will not execute at the new scheduled hour.
If you are acquiring serial data, you can end the data collection from either the LCD
menu of the Model 306 (by pressing in the Select switch) or from the keyboard of your
computer (using the
n
command). If you wish to continue operation from the LCD
menu, you must end data collection from the LCD menu. Likewise, if you wish to
continue operation from the computer keyboard, you must end data collection from the
keyboard. (Otherwise, it may be necessary to power cycle the Model 306 if you wish
to resume operation in your preferred mode.)
5.3
Hibernate Feature
Most remote applications require low power consumption. The Model 306 has the
ability to enter a “hibernation” mode where the firmware powers only the essentials to
consume less power while waiting to output ozone for a calibration or other
experiment. During hibernation, the valve is open to air from the sample inlet of the
Model 306.
•
hibernate
Entering this command turns the pump and lamp off while
maintaining the set temperature of the photolysis chamber and awaits a
character through the serial port (any character) or select switch press to wake
out of hibernation. This is feature is useful for on-demand calibrations in cold
weather applications. Also, this feature must be activated whenever the
scheduler hour is reset from the serial menu, as noted in Section 5.2.
•
hibernate
–nt
Entering this command turns the pump, lamp, and heater off
and awaits a character through the serial port or select switch press to wake
out of hibernation. This feature is useful where power is highly limited.
