13. ERROR DISPLAY

Error display

Description

Above measuring range error

The viscosity value exceeds the upper limit of the viscosity

measuring range (SV-10: 11.99 Pa

⋅

s, SV-100: 119.9 Pa

⋅

s).

The viscosity of the sample can not be measured.

This error may occur when the display unit is not connected to

the main unit.

Below measuring range error

The viscosity value is below the lower limit of the viscosity

measuring range (SV-10: 0.30 mPa

⋅

s, SV-100: 0.90 Pa

⋅

The viscosity of the sample can not be measured.

This error may occur when the display unit is not connected to

the main unit.

The power supply for the internal clock is depleted.

Press any key to enter the clock correction mode. Setting the

clock enables the viscometer to be used temporarily.

If the error occurs frequently, contact the local A&D dealer for

repair.

Internal IC error

Turn the power off. Then, turn the power on again. If this does

not release the error, contact the local A&D dealer for repair.
