Power

Power to the bath is provided by an AC mains supply. See Section 3.1, Specifi-
cations, for power details. Refer to and read the CAUTION at the front of this
manual concerning brownout and over voltage protection. Power to the bath
passes through a filter to prevent switching spikes from being transmitted to
other equipment.
Turn the bath on by switching the control panel power switch to the ON posi-
tion. The stirring motor turns on, the LED display begins to show the bath tem-
perature, and the heater turns on or off until the bath temperature reaches the
programmed set-point. When powered on the control panel display briefly
shows a four digit number. This number indicates the number of times power
has been applied to the bath. Also briefly displayed is data which indicates the
