1.5 Mode of operation
The ViscoClock plus automatically measures the flow time of a liquid in an SI Analytics
®
viscometer to
determine the relative and kinematic (absolute) viscosity. The time measured is the time which a liquid
requires to flow from the upper to the lower measurement mark of the measurement bulb through the
capillaries of the viscometer. The detection of the liquid takes place by the capturing of the liquid meniscus
by means of IR light barriers. The measurement takes place in an SI Analytics
®
thermostat bath
(e.g. transparent thermostats of the series CT 72).
The switch of the viscometer is performed outside the thermostat bath!
The ViscoClock plus consists of a stand tor accommodating the viscometer and the electronic measuring
unit. The two IR light barriers for the meniscus detection are integrated in the plastic stand (PPA). The
electronic measuring unit is built into a polypropylene casing. Owing to the use of heat-carrier liquids as
bath media, color changes may occur on the stand, which do not affect the measurement accuracy.
2 Unpacking and Setup

Scope of delivery: ViscoClock plus
Power supply TZ 1858
Primary adapter for Europe
Primary adapter for USA
Manual pump "pressure“ VZ 6550
Instructions for Use
There are no viscometers included in the scope of delivery.
Remove the ViscoClock plus , the power supply TZ 1858 and the manual pump VZ 6550 from the
packaging.
Place the ViscoClock plus in a dry environment on a plane surface.
Ambient temperature: + 10 ° C ... + 40°C (see

1.2 Specifications ).
Owing to the small stand foot and the relatively high center of gravity we recommend storing the
ViscoClock plus always in a horizontal position outside of the bath.
Use only the included power supply TZ 1858 (labeled: FW 7650/ 9)
or another released power supply by the manufacturer!
Place the power supply easily accessible in order to be able to remove the ViscoClock plus anytime
easily from the power circuit.
