OPERATING INSTRUCTIONS

Alarm temperature setting

This unit is provided with the high temperature alarm. The setting of high temperature alarm is 10oC or 15oC higher than the setting of chamber temperature. The procedure in table 2 shows the sequence to set the high temperature alarm at 15oC higher than the setting of chamber temperature. Set the figure to 000 at step 5 when setting the high temperature alarm at 10oC higher than the setting of chamber temperature.

Note:

The alarm temperature is set at the factory 10oC higher than the setting of chamber temperature.
