Precautions for operation of high and low temperature box

1. The high temperature is still maintained outside the door, which is easy to cause an alarm.


2. Please note that the cabinet must be safely grounded to avoid electrostatic induction.


3. Avoid continuously opening and closing the refrigeration unit within 3 minutes.


4. If the heating sample is placed in the high and low temperature box, please use an external power supply for the sample power control. It is strictly forbidden to use the power supply of this machine directly.


5. Circuit breakers and over-temperature protectors provide safety protection for the tester and the operator, so please check them regularly.
