Power Inlet - At the rear of the calibrator is the removable power cord inlet that
plugs into an IEC grounded socket.
CAUTION: Do not plug the unit into 220V if the unit is indicated as 110V. This
action will cause the fuses to blow and may damage the instrument.
Fan - The fan inside the calibrator has two speeds and runs continuously when
the unit is being operated to provide cooling for the instrument.
The fan runs slow for heating and maintaining operation and runs fast for rapid
cooling. Slots are provided for airflow. The area around the calibrator must be
kept clear to allow adequate ventilation. The airflow is directed out the front and
can be extremely hot
