Using Automatic
Calibration
3-12
The MMS-3 automatically calibrates itself (Auto-Cal) at user-
selectable intervals. Auto-Cal compensates for any drift in the
electronics. GE Sensing recommends setting the Auto-Cal interval to
eight hours (480 minutes). Set a smaller interval to
Auto-Cal more frequently if the MMS-3 is exposed to extreme
temperatures or weather conditions.

Be sure the number displayed in the upper right-hand corner of the
screen is the channel you want to program. If not, press the
key to select the desired channel.
Autocal Interval
01:00 (HH:MM)
After you exit the user program, the MMS-3 immediately performs
Auto-Cal. The next time Auto-Cal occurs will depend on the length of
the time interval set, as shown in the example below.
Example:
The MMS-3 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 90 minute 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 AM
2. 3:00 AM
3. 4:30 AM
4. 6:00 AM
5. 7:30 AM
6. 9:00 AM
7. 10:30 AM
8. 12:00 PM (Noon)
