IKA ROTAVISC Calibration Check

1. Select your ROTAVISC model and the spindle

2.For relative spindle:
Fill a 600 ml beaker (low form) with a standard oil and wait until it has been heated up to 25 °C (± 0,1 °C). It can take some hours. Use a spindle and guard leg (only for lo-vi and me-vi). Use a thermostat (e.g. HRC 2 control) to control the temperature inside the 600 ml beaker.

For absolute spindle:
Fill the corresponding measuring chamber (with the volume mentioned in the manual of each spindle type) with a standard oil and wait until it has been heated up to 25 °C (± 0,1 °C). It can take some hours. Use a thermostat (e.g. HRC 2 control) to control the temperature inside the measuring chamber.

3. Enter the viscosity of your standard oil (value at 25 °C from certificate or on label of standard oil packaging), e.g. CAL-O-12500 with a viscosity of 12,257 cP at 25 °C.

4. Enter the first speed, e.g. 10 rpm, for the calibration check.
Start the viscometer measurement at this speed. Wait until the values are stable.
The minimum speed should generate a torque of min. 10%
Value 1: 10 % - 20%
Value 2: 30 % - 50 %
Value 3: 60 % - 100 %

Enter the first viscosity value that has been measured.
