completed.
Handling Precautions
• In the PV input calibration, always adjust all gains.
• Do not leave the PV input terminal open during heat-up between
power ON of this unit and starting of calibration. When the input type is
thermocouple or DC voltage, put the unit in the 0 volt input (or terminals
are short-circuited) status. When the input type is RTD, put the unit in the
100 -input (or terminals are short-circuited) status.
