Introduction
Fluke’s Hart Scientific Division’s 2200 Temperature Controller is a solid state
temperature controller. A unique combination of analog and digital electronic
circuitry provides exceptional accuracy and stability together with ease of oper-
ation and programmability.
Temperature sensing is done with a 2-wire 100 ohm platinum resistance probe
which plugs into the back of the controller. To maintain a constant temperature
the power to the heater is pulse width modulated by means of a solid-state re-
lay. The maximum current rating of the controller is 10 amps.
The 2200 controller can be easily programmed via the four-button front panel
or by the serial interface. Programming allows the user to set the control tem-
perature, units °C or °F, and the calibration variables. The process or actual
temperature is continuously displayed on an LED panel. The percent heating
power may also be monitored.
Before using the 2200 controller, you should understand the proper setup and
operation.
