2. Introduction
IntroductionIntroduction Introduction
The temperature calibrator consists of a digital thermometer
and a sensor pan with a K-type thermocouple in the center.
The instrument displays the temperature data used at the
calibration of the drying temperature.
Install the battery before use.
Refer to 5. Battery Replacement.
Refer to the Calibration of Drying Temperature for MX-50
for the temperature calibration method.
Caution
• Do not input a voltage that exceeds 24VAC or 60VDC,
to avoid getting an electric shock.
