VERIFICATION
OF YOUR DEVICE
Your instrument is calibrated at the factory with an ASTM L2 mobile and a certified oil with a
viscosity close to 1000 mPa.s.
Viscosity measurement on a 1000 mPa.s standard silicon oil with ASTM 2555 L2
measuring system.
- Fill the 600ml beaker with the standard oil.
- Insert the 600ml beaker in a controlled temperature unit like EVA LR system or thermostatic
bath.
- See section 3.1 and install spindle L2.
- See section 2.2.2. Select spindle L2 and speed 60 rpm. Make a zero adjustment.
- See section 3.2 and immerge the spindle in the oil at the good level (mark on the spindle).
- Wait for 15 minutes until the standard oil rise the good temperature.
- Select 60 seconds for the measuring time, and start the measurement at 60 rpm.
Result at the end of the measurement must be /-5% of the standard viscosity value. If
the measure is out, your instrument might need to be recalibrated.
Check if the error does not come from a wrong filling, a wrong zero adjustment, a wrong
spindle rotation, or a wrong temperature value.
