3. Brightness setting
To maintain a constant brightness within the chamber,
perform the following setting using the keys on the control
panel.
When the unit is in PV status (the display shows the present
value within the chamber and the PV lamp is lit), press the
digit shift k� ( ).

4. Humidity control (MLR-350H and MLR-350HT only)
The unit has no humidity program operation function.
The internal humidity in the chamber can.be set

than the setting.
The dehumidifier mode switch should be set

To disable the humidity control function, enter a value of 00% RH as the humidity setting.
Note:
Humidity control does not begin until the temperature within the chamber has stabilized to within 1.3

Moisture may condense inside the chamber if the humidity setting is high.
If the humidity setting is very low, a considerable amount of time may be required for the actual humidity to
reach the set value if the interior of the chamber is wet or very humid to start with.
