Thermistor Probe Installation
Connections for two thermistor probes are located on the back of the 6772 Calorimetric
Thermometer. If only one probe is to be used, connect it to the “bucket” connection. The
6772 Calorimetric Thermometer includes an ignition unit for automatically firing the bomb in
the 1341 calorimeter. The ignition leads to the thermometer need to be connected to the red
and black terminals marked “Ignition” on the back of the thermometer to take advantage of
this feature. The thermistor probe should be set so the bottom tip is 6 inches below the
underside of the calorimeter cover. Connect the A1877E (2) extension cord from the motor
to the 6772.
