Common precautions
•
Keep the time for one measurement under 100 seconds.
•
Ambient conditions for operation of the unit are as follows:
temperature range 5°C to 35°C, relative humidity 10% to 90%RH.
•
Because the drive section is not hermetically sealed, do not use the unit
in environments with volatile gas or dust pollution. Otherwise the drive
section may be damaged.
•
When attaching or removing a rotor, put the viscotester in a horizontal
position and carefully move the rotor in the vertical direction. To prevent
the possibility of damage, take care not to exert strong force on the rotor
mounting shaft in the vertical or horizontal direction.
•
The rotor mounting shaft is screwed into the body of the unit. Take care
not to inadvertently dislodge it when attaching or removing a rotor.
