¡Wearing protective glasses! 

 

    Ensure that the silicone oil does not come into contact with eyes. 
 

 

Clean the trunk.

 

 

Clean sensors before performing the calibration.

 

 

Replace worn-out magnetic stirrer.

 

 

Replace the tainted and muddy calibration liquid.

 

 
 

6.8.2. Filling the micro calibration bath 

 

1. 

Remove the cover transport LID first.

 

2. 

Insert the testers in the basket for the sensor.

 

3. 

Fill the trunk with calibration liquid.

 

 

The following maximum filling heights are recommended by type:

 

 

 

Micro bath type                                                 

 

Maximum filling height

 

LCA 30 

150 mm 

LCA 50 

150 mm 

 
 

The following aspects have to be taken into account in terms of the maximum filling height:  
 

 

Measure from the bottom of the basket for the sensor. 

 

 

No tank filled.

 

 

Leyro Instruments standard filling medium.

 

 

Filling from the Factory with the optimum height. 

 

 

 
The  transport  lid  is  equipped  with  a  safety  valve.  If  the 
micro-calibration bath is closed in a hot state, inadmissible 
pressures  may  occur.  To  avoid  the  overpressure  that  can 
destroy  the  liquid bath,  the safety  valve  is  activated  with a 
precision  of  approximately  2.5  bars.  In  this  way,  hot 
vapours can escape. 

 
 

 

6.8.3. Operating the magnet stirrer and basket 

 

The maximum homogeneity is obtained with the magnetic stirrer bar at maximum speed. 
 
Adjust the  agitation speed  with the  potentiometer,  to  the  right the speed  is  increased  and to 
the left it is decreased.  
 
The basket is removable. 

 
 

 

 

The magnetic stirrer bar is a wear part.
