This unit performs two basic functions.
1. Thermostatic power control of the MS2WF furnace. It supplies electrical power to the furnace
and provides either pre-set thermostatic control of temperature, or slowly varying linear
increase or decrease of temperature. The ramp rates can be controlled manually.
2. Routing data transmissions. Serial interface connection between the user’s computer, the
MS2/MS3 meter and the digital thermometer is via this power supply unit.
