Application Guide

please use the external temperature sensor PT100.

internal for temperature control are built into the hotplate. The

single external PT100 can monitor the temperature of sample.

Working with the external temperature sensor

The external temperature sensor PT100 is an optional accessory.

When the sensor is connected, the sensor indicator will light and

the machine is in the PT100 operation mode. The setting

temperature of the external sensor and the actual temperature

are displayed. The safety circuit controls the hotplate temperature.

Comparing with the temperature control of hotplate, the external

temperature sensor can control the sample’s temperature more

precisely. The externa temperature sensor must be inserted in the

sample. For any faults, heating will be automatically stopped. In

this case, please proceed as follows:

- Turn power off

- Ensure the external temperature sensor is inserted into the sample

- Turn on and set the temperature to start heating

- If the instrument still can’t work properly, please contact

manufacturer / supplier for technical support.

Residual heat warning (HOT)

To prevent the risk of burns from the hotplate, this instrument has

residual heat warning function. When heating is stopped, and the

heating plate temperature is still above 50°C, the setting indicator

will light up to warn that there's potential risk of burns. When the

hotplate temperature drops to below 50°C, the instrument will be

automatically powered off. To turn off the instrument immediately,

pull out the plug. In case of main power failure or disconnection,

the residual heat warning will not work.
