The MAS-CAL is the field
calibration unit for the MAS sensor. It is designed to operate off of either 9V
battery
or external 24VAC power supply. The
MAS-CAL provides the MAS sensor with power from either source.
The MAS-CAL is used to view the
settings of the MAS sensor and be able to halve or double the factory set
full scale range of the sensor and
be able to double or reset to zero the factory set timing. The MAS-CAL
works with all MAS sensors, even
when each has different factory settings because all of the changes are
relative to the factory preset
values.
