TEMPERATURE RE-ADJUSTMENT
Shaking incubator has a software for temperature re-adjustment. First you have to measure
the temperature in the middle of the chamber, or even better in the sample, for minimum 2
hours. You have to measure the temperature with a calibrated digital temperature
thermometer, with precision 0.1°C or more. After 2 hours or more, read the temperature on
thermometer and compare it with the temperature on display of the shaking incubator. The
difference between the temperatures on thermometer and display is the value, which you
enter in the software.
Example 1: Temp. on thermometer is 37.9°C, temp. on display is 37°C. Difference is
37.9 - 37 = 0.9. Value is 0.9 (which you enter in the software).
Example 2: Temp. on thermometer is 36.2°C, temp. on display is 37°C. Difference is
36.2 - 37 = -0.8. Value is -0.8 (which you enter in the software).
Procedure for temperature calibration:
 Press and hold encoder knob for more than 5 seconds - message Cor (correction)
appears on display.
 Press encoder knob once to enter the value setting procedure and set the value with
rotating encoder counter-clockwise or clockwise (see Example 1 or Example 2). Pay
attention to the sign of the value (plus or minus). When you set the value, press
encoder knob again.
 Press START/STOP key to finish the temperature re-adjustment.
Note: Temperature re-adjustment procedure is only for qualified technical persons.
8.0 MAINTENANCE AND CLEANING INSTRUCTIONS
8.1
CLEANING OF THE WORKING CHAMBER (PAINTED STEEL)
Working chamber should be cleaned regularly. Every spilt sample inside the chamber must
be immediately wiped. You can only use mild cleaning solutions. Usage of aggressive or
abrasive cleaners is not allowed.
For decontamination use cleaners with neutral Ph. Stainless steel platform can be
decontaminated with autoclave (120°C).
8.2
MAINTENANCE AND CLEANING OF THE PMMA (ACRYLIC) LID
Maintenance:
Acrylic glass is sensitive to scratching. For cleaning, use only non-aggressive liquid
detergents and non-solids. Do not use the hard sponge, but only a soft cloth.
Grease and oil can be cleaned with hexane, petroleum or other chemicals with the aromatic
base.
