Maintenance
Follow the maintenance precautions listed below. Perform these tasks regularly and
at least within the periods given:
Before use
Make sure that the measuring systems are clean and free from scratches. Never try
to attach or use any measuring system which has visible damage.
Caution!
Take great care when handling measuring systems. Attach and remove
them carefully. Return them to the storage case when not in use.
After making a measurement
When the measurement is over:
1.
Press the START button to stop the motor. If all measurements are complete
switch the instrument off.
2.
Lift the upper measuring system clear of the lower one. If the sample is very
stiff or 'stringy', undo the upper measuring system before lifting the viscometer
out of its clamp. This leaves the upper and lower measuring systems behind
and both can be removed together
.
3.
Lift the viscometer and remove the measuring systems. Clean the viscometer
covers, stand and base plate with soapy water.
Caution!
Do not use excessive amounts of water and take care near the front panel,
rear connection panel, etc.
Frequency Task
Weekly Check the fluid level of the Temperature Control Unit (TCU).
Top this up if required.
Monthly Run a calibration reference sample (oil) to confirm that the vis-
cometer is still within calibration.
Yearly Arrange a service visit by a Malvern Instruments representative.
