Installation
1
、
Take out base, lifting column, handle from the packing box. Screw
the column into the base ( rack side towards the user). Fix handle
onto the lifting block.
2
、
Adjust lifting button for tightness. Put T-shaped block on the rear
of the instrument into handle and get it fixed, making the instrument
balanced.
3
、
Adjust 3 screws on the base to keep the level bubble at the center
of the black circle.
4
、
Take off the protection cap at the bottom of the instrument.
5
、
Plug in.
5. Operating Procedure
1
、
Prepare liquid sample to be tested, pour it into beaker or flat
container with diameter no less than 60mm. Control the temperature
of the liquid sample correctly. (Variations of temperature will affect
viscosity directly.)
2
、
Screw anti-clockwise protection bracket (T-shape) into the bottom
end of the instrument
3
、
Choose appropriate rotor and screw it anti-clockwise into the
connector. Attention: slightly lift direction connector up when rotor is
installed to avoid damages to the pivot.
4
、
Turn lifting button to slowly immerse rotor into the liquid until the
marker on the rotor (groove or marking line) is aligned with the liquid
level.
5
、
Adjust the balance of the instrument again.
6
、
Should keep testing temperature stable to ensure accurate read out.
Otherwise readout may fluctuate.
6.
Panel Operation
Turn on power switch on the back of the instrument and the
instrument is on standby. The following information will be shown on
the panel.
S1 V6 T.....
℃
%... CP 000000
If Rotor 1 is used at 6RPM/min, can directly press the start
button on the panel to initiate testing. When display values become
stable, read the CP value. (In order to make readout stable, if viscosity
is relatively low, turn rotor about 3-5 rotations; if viscosity is
relatively high, turn rotor about 1-2 rotations.)

If what the user chooses is not the default value S1 and V6, press
rotor select and speed select button to enter selecting status, then press
confirm button to confirm. When set-up is done, press start button to
initiate testing.
Rotor S0~S4 and V0.1/V0.3/V0.6/V1.5/V3/V6/V12/V30/V60
will scroll displaying repeatedly.
Explanations:
S: stands for Rotor number. S1 refers to Rotor 1. (default value)
V:stands for rotation speed. V6 refers to 6RPM/min. (default
value)
T:.....
℃
: Temperature
%........: test value’s percentage rate of the full value of the
measuring range.
Cp: mPa
·
S Viscosity value
For example: If the viscosity of the liquid to be tested is estimated
3000mPa
·
S, it is recommended to choose the
combination S2
，
V6 or S3
，
V0.3
For the correlations between the combination of rotor and rotation
speed and the corresponding viscosity range, please refer to the below
table.
