3-8 Advanced Programming
Using Automatic
Calibration (cont.)
To set the Auto-Cal interval, do the following. (Figure 3-19 on page
3-32 for a menu map.)
Note: The Reference Menu has three tables: one each for moisture,
oxygen, and pressure references. You can use any one of these
Tables to set the Auto-Cal interval.
1. At the Reference Menu (see Table 3-3 on page 3-7), press the
INTERVAL menu key.
2. Using the numeric keys, enter an Auto-Cal interval between 0 and
24 hours and press [YES].
3. Press the DONE menu key. The meter begins Auto-Cal. Wait for
the Auto-Cal to complete and continue pressing the DONE menu
key until Main Menu appears on the message line.
The next time Auto-Cal occurs will depend on the length of the time
interval that was set. See the example below.
EXAMPLE:
The Series 1 establishes a fixed schedule, beginning at midnight,
using the interval specified to determine the times of subsequent
Auto-Cals. For example, if you enter a 1 hr., 30 min. time interval,
Auto-Cal will occur 16 times per day (1 day = 1440 minutes ÷ 90
minutes = 16). The fixed schedule will be as follows:
1. 1:30 a.m. 9. 1:30 p.m.
2. 3:00 a.m. 10. 3:00 p.m
3. 4:30 a.m. 11. 4:30 p.m.
4. 6:00 a.m. 12. 6:00 p.m.
5. 7:30 a.m. 13. 7:30 p.m.
6. 9:00 a.m. 14. 9:00 p.m.
7. 10:30 a.m. 15. 10:30 p.m.
8. 12:00 p.m. (noon) 16. 12:00 a.m. (midnight)
If you set the 1 hr., 30 min. Auto-Cal interval at 6:10 p.m., the next
Auto-Cal will occur at 7:30 p.m. (excluding the Auto-Cal performed
when first leaving the Reference Menu).
