4. Connect optional equipment (e.g. printer) to the
corresponding interfaces. See section 2.2.

ture before installation. This is very important if
the equipment has been stored or transported at
lower temperatures.
4.2.1 Connecting and Switching on
ViscoQC 300
1. Connect the power supply unit of ViscoQC to
the mains using the supplied power cord.
2. Connect the power supply unit and the power
inlet of ViscoQC (section 2.2).
3. Switch the instrument on using the power switch
on the rear of the measuring head. ViscoQC
boots.
4.2.2 Level/Zero Adjustment
1. Wait that ViscoQC initializes.
2. Level ViscoQC by turning the two leveling
screws on the foot of the stand. An adjusted,
built-in leveling chip serves as reference. Center
the colored dot in the colored ring (see Fig. 6,
steps A to C).
A: RED – Adjust the two leveling screws.
B: YELLOW – Wait; the instrument stabilizes.
C: GREEN – ViscoQC is correctly leveled.
Tap <OK> to continue.

If you skip the level adjustment, you directly
jump to the main screen. It is not possible to
measure, you can only open the menu and
quick access functions.
Zero Adjustment
For correct function of ViscoQC the instrument de-
termines the start position for zero torque without
load (i.e. spindle or measuring system).
1. ViscoQC prompts you to remove the spindle.
Tap <Next> to continue.
2. ViscoQC performs a Zero Adjustment. Do not
touch the instrument. Once the Zero Adjustment
is finished, tap <OK>. ViscoQC displays the
Autozero Offset.
In case you abort the Zero Adjustment by tap-
ping <Abort> and then <Cancel>, you can
access main screen and menu, but cannot per-
form measurements.
3. ViscoQC is now ready for operation. Connect a
spindle or measuring system.
