TEMPERATURE SETTING

Chamber temperature

Table 1 shows the basic procedure for setting the chamber temperature. Perform key operations in the sequence indicated in the table. The example in the table is based on the assumption that the desired temperature is -25oC.

Note: The unit is set at the factory that the chamber temperature -30oC.
