Section 3
Operation and Calibration
In the "Explanation of Controls" section, all of the control panel keys were
discussed. In this section, some of those keys will be discussed in greater
detail due to their more involved operation.
1. Clock Key
- Pressing the CLOCK key will enable the user to select the
hours, minutes, and day. The clock will continue to function correctly
if the growth chamber's power has been removed.
The date, month, and year selection is performed in Configuration
mode and will be discussed later. The date, month, and year have been
preset at the factory. If required, see CALENDAR in this section.
A. Press the CLOCK key and the displays will show the following:
A number other than 10 might be shown in the right display. Also,
if no keys are pressed within 15 seconds, the displays will return to
their previous state.
Using either the up or down arrow keys, the user can select the
correct hour of the day. After the correct hour has been selected,
ENTER must be pressed and the displays will change to those
illustrated in Step B. If the hour was correct when the CLOCK
was pressed, press ENTER and the displays will change to those
shown in Step B.
B. The displays will be similar to those below. These are for the
minute selection.
Again, a number other than 21 will most likely appear. This
display also has a 15-second time-out, just as the hour display.
Also, the next two displays in Steps C and D will have a 15-second
time-out.
If the minutes are correct, press the ENTER key and the displays
will go to those in Step C.
If the minutes are incorrect, use the up or down arrow keys to
select the correct minutes and then press ENTER. The displays
will go to those shown in Step C.
