The external temperature sensor PT1000 is manufacture’s
standard accessory. If the sensor is plugged in, “Probe” will
be shown on the LCD digital display to indicate the sensor
is operating. The setting value of external temperature
sensor and actual temperature are displayed. Safe circuit
controls hotplate temperature. Comparing with the
temperature control of the hotplate, the external
temperature sensor can control the medium’s temperature
more precise. The heating function will be stopped
automatically under abnormal conditions. Please operate
follow the instructions below:
• Switch OFF the instrument.
