INSTALLATION
Power Connection
Plug the power line into any grounded outlet providing proper voltage that matches the
specification on the nameplate of the Calorimetric Thermometer. The thermometer will draw
approximately 100 watts of power. Grounding is very important not only as a safety
measure, but also to ensure satisfactory controller performance. If there is any question
about the reliability of the ground connection through the power cord, run a separate earth
ground wire to the controller chassis.
Turn the power switch to the on position. After a short time, the Parr logo will appear on the
LCD display followed by a running description of the instrument boot sequence. When the
boot sequence is complete, the 6772 Calorimetric Thermometer Main Menu is displayed.
Motor Connection
Disconnect power before connecting a motor to the Calorimetric Thermometer. Remove
493E Plug with 3280HC Retainer and attach the motor cord to the rear of the calorimeter
case using the mounting screws provided for safety purposes.
