7. Handling the micro bath
Angular sensors, sensors with larger diameters or with special designs can be calibrated in a micro-bath. That's why
bathrooms are the most appropriate tool. The liquid circulates with the help of a magnetic stirrer, ensuring a very
good temperature distribution in the bath. The liquids used are selected based on the desired calibration
temperature.
The micro-bath is heated or cooled until the desired calibration temperature is reached. When the temperature is
stable, the temperature probes to be calibrated are compared with the reference thermometer
7.1 Operating in calibration mode in each operation mode
Operation mode of operation
The equipment must be turned off
Place the magnetic stirrer bar and the basket for the sensor
Fill the calibration micro bath with the necessary fluid
Switch on the equipment
Activate the magnetic stirrer bar with the potentiometer
Introduce probes to calibrate
Adjust the speed of the magnetic stirrer bar to achieve the most highest homogeneity
Cleaning operating mode
Stop the speed of the magnetic stirrer bar
Switch off the instrument at ambient temperature (approximately 25ºC / 77ºF)
Remove the liquid with a syringe
Remove the basket and the magnetic stirrer bar
Remove excess fluid
Clean the tank with alcohol or water
Once clean, introduce the magnetic stirrer and the basket again
7.2 Starting Screen
We connect the equipment to the power supply and turn on the alternating current switch. We wait
the equipment to be started completely (30s).
Before beginning, any modification not expressed in this manual, Leyro Instruments is not
responsible for the malfunction of the same. The equipment stores all the modified data from
its first start and in case the equipment needs to return to the factory due to malfunction by
these, it will be excluded from guarantee
For any modification expressed in this manual, we must press done to save the changes
When the equipment has been fully started, it will start to control by default with the Internal PT100
and the PT100 Ext key will be deactivated, shown in gray, with which, the internal control will be
activated and the external control will be deactivated.
If it is necessary to control with External PT100, press the PT100 Ext key, which will be activated
and represented by green color, with which the internal control will be deactivated and external
control will be activated.
