Advanced Programming
Using Automatic
Calibration
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.
Press the
[PROG]
key to enter the user program.
Note:
If you have already entered the user program, see Figure 3-2
on page 3-48 to navigate to the Autocal Menu.
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
[CHAN]
key to select the desired channel.
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:
