T LOSS COMPENSATION function is disabled The standard CONTROL THERMISTOR is the sensor located in the heating cooling device This sensor is placed at the optimal point to control the temperature of the heating cooling device The MONITOR THERMISTOR is the peripheral thermistor that can be used to monitor the temperature at another location in the experimental configuration This thermistor monitors the temperature at the selected point in the experiment and is more accurate but is less stable in the control loop because of the delay between heating or cooling and sensing To protect the experiment if the monitor thermistor is removed the limit of the increase in temperature between the control and monitor thermistors in the feedback loop is 8 C This lowers the probability of overheating the experiment to the point of damage There is no protection from overcooling caused by a misplaced monitor thermistor A switch above the T2 INPUT CONNECTOR provides selection of the thermistor impedance for both the control thermistor T1 and the monitor thermistor T2 for that channel The thermistor impedance for Warner Instruments equipment is 10kQ 25 C while the thermistor impedance for Harvard equipment is 100kO 25 C An indicator on the front panel indicates an open thermistor fault of the selected feedback thermistor Normally if a thermistor becomes open as in a broken wire the controller sees this as a lower temperature The controll
