b) Clothes Dryer
Type:
Kenmore front loading clothes dryer
Model:

Input Voltage: 220 ~ 240 V, 60 Hz
The following list contains the specifications and calibration factors of the test
equipment. The calibration factors were verified using known sources and were
calculated according to the following:
Calfac = Refval / Outvol
in Engineering Units per Volt
Calfac  Transducer sensitivity
Refval  reference value of the calibration source
Outvol  output voltage of the transducer
