1. In order to prevent electric shock or malfunction, do not turn on the power before installation and wiring can’t be completed.
To avoid machine failure in the constant temperature and humidity chamber, please use rated voltage range power.
2. Please do not open the test box door during the operation of the instrument. If it is opened at high temperature, it may cause burns to the operator.
If someone opened the chamber at a low temperature, it may cause frostbite and may cause the evaporator to freeze, and it will also affect the cooling effect.
3. Don’t let dust, thread, iron filings or other things enter the machine during installation, otherwise malfunction will occur.
4. Don’t process, modify or repair the constant temperature and humidity machine without authorization, otherwise it will cause abnormal operation, electric shock or fire.
5. Wiring should be correct and grounded. Otherwise, it may cause electric shock, malfunction, abnormal display, or margin errors in measurement.
6. During the operation of the instrument, as the power supply is forced, the terminal cover must be installed on the terminal block to prevent electric shock.
7. Please check the terminal screws and the holder regularly, and do not use them in a loose condition.
The safety should be fully considered before modifying the setting, signal output, starting, stopping, etc.
If wrong operation happens, it may cause the working equipment to be damaged or malfunction.
8. Use a dry cloth to wipe the meter, do not get water on the meter, if the meter is immersed in water, stopping using it immediately, otherwise leakage, electric shock or fire will happen.
The internal parts of the instrument have a certain life span. In order to use the instrument safely, please perform regular maintenance
