II.7OutofRange
e DVE gives indications for out of specication or out of range operation. When torque %
readings exceed 100.0% (over range), the display changes to that shown in Figure
II-10. You must
either reduce the speed or use a smaller size spindle to correct this condition. Audible noise may
be heard in this case.

If you operate at spindle speeds that produce torque below 10.0% (under-range), the DVE displays
both torque % and viscosity (cP) with ashing unit designations, as shown is Figure II-11. You must
either increase speed or use a larger size spindle to correct this condition.
e parameters of torque % and viscosity (cP) will also ash prior to two complete spindle revolutions.
It is not recommended that readings are taken while parameters are ashing.

Negative torque % will be displayed as shown in Figure
II-12. Viscosity values will be displayed as
“- - - -” when the torque % is below zero.
