Operation of magnetic stirrer:
The speed of the magnetic stirrer is set via the thumb wheel (
Fig.) next to
the controller.
Set the speed to the respective maximum to achieve a thorough mixing.
Turn the thumbwheel upwards to increase the speed.
Turn the thumbwheel downwards to slow down the magnetic stirrer.
Drain pump and magnetic lifter:
The drain pump is used for pumping out the calibration liquid from the tank of the micro
bath. The magnetic stirrer is removed with the help of the magnetic lifter.
Both the activities are required before another adapter sleeve or calibration insert is inserted
in the calibrator.
Tub insert (optional / accessory):
We recommend using a tub insert if you
•
frequently change between dry block, infrared, surface and micro
bath function.
•
frequently work with different calibration liquids.
The tub insert is placed into the tank with the help of the sleeve exchange
tool.
Just like the tank, the tub insert can be closed with the associated cover.
Both threaded covers are leak proof, so the calibration liquid can be left in
the tank or the tub insert during transport.

Notes on the calibration liquid
Different calibration liquids supply varying calibration results due to their specific
characteristics. Adjustment to the respective calibration liquid has to be carried out by the
manufacturer.
In order to achieve the best possible accuracy of a micro bath, it has to be filled with a
suitable calibration liquid (
§ 2.1 "Safety instructions for the application of calibration
liquids").
The calibration liquid is poured directly into the tank or into a tub insert.
When using water as the calibration liquid:
Only use distilled water, otherwise excessive limescale and soiling will build up in the
tank.
When using silicone oil as the calibration liquid:
Wear safety goggles for the eyes without fail when working with silicone oil!
Use only the silicone oil recommended here.
