Display
After start or reset viscosity , show the model at first.(LPDV-1)
LPDV-1
After 3 seconds
：
“25.5
℃
”means the temperature measured by PT100.
“SP B1”means spindle number “B1”. The same as “SP B2”.
“60 RPM”means speed of stepping motor is 60 rounds per minute.
“83.3 mPa.S”means the full range with the speed and the spindle.
After press “M”button ,screen will show the viscosity like:“888 mPa.s”at the place of the full range.
“45.7%” means torque. It’s common that the value is in the range of 10% to 90%. If not, viscosity will
alarm to advise users to change the speed and spindle.

Operation
4.1
Install viscometer
4.2
Open the power switch. If screen shows nothing, it means lithium battery is without electricity. Insert
battery charger into viscometer. The red indicator runs. About 3 hours later, the green indicator light runs
and charging complete. After that viscometer can be used without charging for 8 hours.
4.3
Click “S”button to change spindle number. (B1 → B2 → B3 → B4 → B1)
The number must connect with the real spindle.
4.4
Click “R”button to change speed. For example: 60, 100, 150, 200 rpm.
4.5
Click “M”button to start to measure the viscosity and torque with the spindle and the speed.
4.6
Changing spindle during measure: Click “M”button to restart. Motor stops. After changing spindles,
do 3rd and 4th step again to go on the measure.
4.7
“Print” and “Timing”

．
Timing
：
Click “P” button. Screen show “S:00:00” in the bottom left. It changes with the click of “P”
button (00 :00 → 00 :10 → 00 :30 → 01 :00 → 02 :00 → 03 :00 → 04 :00 → 05 :00 →10:00
→15:00→20:00). This number is the time to complete the measure.
b. Print: Connect with the miniprinter. Click “P” and the miniprinter will print “on”. It means the
printer start. Click “P” once more, it print “off”. It means print is over.
