14. TROUBLESHOOTING (FOR ALL MODELS)
The viscometer is a precision instrument. When the operating environment or the operating method
is inadequate, correct values can not be obtained. If measurement values do not become stable or
they seem to be incorrect, check as described below. If improper performance persists after
checking, contact the local A&D dealer for repair.
14-1 When measurement values do not become stable (For all models)
 Is the ambient environment free from vibration and drafts?
 Places such as second or higher floor or near busy highways or rail lines are prone to
vibration.
Avoid these places or use an anti-vibration table, AD-1685.
 Reconsider the setting of "Condition (Cond) ” of the function setting.
Set it to "Cond 2".
 Avoid direct drafts in the vicinity of the viscometer.
 Is there a strong electrical or magnetic noise source such as a motor near the viscometer?
 Install the viscometer away from the electrical or magnetic noise sources
 With SV-1A/SV-1H, if the sensor plate touches the inner wall of the 2 mL cup, the displayed
value will not stabilize. Adjust the spacing between the sensor plate and the inner wall of the 2
mL cup.
 Is the protector or the sensor protective cover in contact with the sensor plates or the
temperature sensor?
 Attach the protector and the sensor protective cover properly so that they do not touch
the sensor plates or the temperature sensor.
 Remove the protector, the surface locator plate or the sensor protective cover when
necessary.
(1) How to remove the protector (For all models)
Press the left and right side frames lightly in the direction indicated as 1 to remove the
rotational axis. Pull the protector in the direction indicated as 2 to remove.
