%100.0 value will be displayed for as long as the ENTER/AUTO RANGE key is depressed. Figure II-12
shows the AUTO RANGE function for the situation where the No. 1 LV spindle is rotating at 60 rpm.
The full scale range is 100.0 cP (or 100.0 mPa
.
s).
cP 100.0 S61
60 RPM % 100
Figure II-12
Notes:
1. If the RPM is 0.0, the maximum viscosity displayed will be 0.0 cP (or 0.0 mPa
.
s).
2. While the Viscometer is in the Auto Range mode, any data sent to an attached printer
or computer reects the displayed values (i.e. Auto Range values).
3. This function is only available when in the default screen.
II.6 Out of Range
The DV-II+Pro gives indications for out-of-range operation. When % (Torque) readings exceed
100% (over-range), the display changes to that shown in Figure II-13; EEEE will also appear in
the display for % and viscosity or shear stress:
cP EEEE 20.1C
10 RPM % EEEE
Figure II-13
You must change either speed or spindle to correct this condition. If you operate at spindle
speeds that produce % (Torque) below 10.0 %, the DV-II+Pro ashes the % (Torque), cP
(Viscosity), SS (Shear Stress) and SR (Shear Rate) as shown in Figure II-14:
cP 12.4 20.1C
10 RPM % 8.2
Figure II-14
Negative % (Torque) will be displayed as shown in Figure II-15:
cP ---- 20.1C
10 RPM % -2.2
