3.2.3.5 AUTO-CALIBRATION (A.CAL)

This parameter only appears if DIP switch #1 is OFF. With
the Auto-calibration, users can determine after how many
changes in direction the auto-calibration will occur. Users
can select a value from 10 and 250 (and OFF) adjustable
by increments of 10. This parameter can be deactivated,
even though it is not recommended. This parameter does
not appear when a feedback potentiometer is used.
If DIP switch #3 is set to OUTSIDE (assuming the
temperature probe is located outside), then the auto-
calibration may be delayed if
not within a safe range.
Calibration).
3.2.3.6 EXTREME TEMP.(CLd.t or Hot.t)
The Extreme temperature parameter is a safety feature. It
delays automatic calibration when outside temperature is
beyond the acceptable limit. Range: -4°F (-20°C) to 80°F
(30°C).
The parameter only appears if DIP switch #3 is set to
OUTSIDE and if DIP switch #1 is set to time mode. With
this temperature set point, users can tell the SVIM-1
what they consider a cold or hot limit.
