Control Description
(Cont’d)
Cooling Mode Switch (Item C)
Selects between Automatic or Manual operational modes, or center select
for off .
Thermistor Recorder Outputs (Items D, E)
BNC connectors are provided to send thermistor readings to a data acqui-
sition system or chart recorder.
CONTROL TEMP OUT (Item D) reports the actual temperature of the feed-
back thermistor situated within the heater/cooler device being used.
Output is calibrated to 100 mV/ºC.
MONITOR TEMP OUT (Item E) reports the temperature of the sensor ther-
mistor which connects via the MONITOR TEMP IN BNC (Item F). Output is
calibrated to 100 mV/ºC.
Monitor Temp In BNC (Item F)
BNC for connecting a sensor thermistor used to sample the temperature at
a point of interest. Designed for use with the
TA-29
cable assembly.
Loop Speed Switch (Item G)
Sets the feedback loop speed for the CONTROL TEMP THERMISTOR when
the CL-100 is used in automatic mode . Feedback options include fast,
medium , and slow . Optimally set to fast for most applications but can be
set to medium or slow for systems with longer thermal delay characteristics.
Set Temperature Control (Item H)
Used to adjust the set point of the automatic temperature control system.
The associated GREEN LED is on when the INTERNAL/EXTERNAL SELECT
CONTROL (Item J) is set to internal , and the COOLING MODE SWITCH
(Item C) is set to auto . Set value can be read from the METER (Item B) in
the set temp position.
External/Internal Select Control (Item J)
Used to select between internal or external control inputs when the
instrument is in Manual mode (Item C).
When the INTERNAL/EXTERNAL SELECT CONTROL is set to internal , and
the COOLING MODE SWITCH (Item C) is set to auto , the SET TEMPERA-
TURE CONTROL (Item H) will be active. Setting the COOLING MODE
SWITCH (Item C) to manual disables the SET TEMPERATURE CONTROL
(Item H) and activates the MANUAL VOLTAGE CONTROL (Item K).
