• The water supply cannot be interrupted during the operation of the instrument.
· The water supply pressure must be between 1 and 10 bar.
• The water supply conductivity must be between 200 μs/cm and 500 μs/cm.
· The water supply temperature should be below 40 °C.
6.2. Temperature control
6.2.1 Turn on the temperature control switch and press [ENTER] to the temperature control state.
6.2.2 Press the [Pgm] button, use the [s][t] buttons to set the temperature, and press [ENTER] to confirm.
6.2.3 Press the [EXIT] button to return to the main menu.
6.3. Humidity control
6.3.1 Turn on the humidity control switch and press [ENTER] to the humidity control state.
6.3.2 Press the [Pgm] button, use the [s][t] buttons to set the humidity, and press [ENTER] to confirm.
6.3.3 Press the [EXIT] button to return to the main menu.
6.4. When carrying out the accelerated experiment, first read the quality standard of the product carefully, select the temperature and humidity conditions of the accelerated test, and then set the required temperature and humidity values ​​according to the methods of 6.2 and 6.3.
6.5. During the accelerated experiment, the temperature and humidity of the constant temperature and humidity meter should be recorded daily. If any abnormal conditions are found, report it to the laboratory supervisor for maintenance.
