the mark on the axis mobile). Be careful that the tip of the mobile is 10 mm or more from the
bottom of the beaker.
When the measurement height is optimum, use screw on arm to block height of measuring
head. After you can use the stop ring on the support rod to memorize the position.
Wait until the temperature of the sample is within the prescribed limits (if you have temperature
probe with your device).
Start the measurement at the desired speed (same as zero adjustment).
The torque measurement is indicated on the instrument screen using a gage. Ensure that the
measured torque is always sufficiently far from the lower and upper limits (at least 5% above
and below). If this is not the case, you can either change the measuring spindle or change the
rotating speed.
Then your measurement is finished, raise the measuring head and lock it with screw on
aluminium arm as wrote in section 1.2. Remove the measuring spindle to clean it.
3.3. MS ULV
Measuring system for low viscosities usable with instruments LR version (Aluminium).
This system, unlike the MS-ASTM or MS-DIN systems, makes it possible to measure low
viscosity products in control by applying a shear rate. Its advantage is to be compatible with
instruments in LR version unlike all other measuring systems.
