If you are not using the spectrophotometer for a long period of time please make sure

it is disconnected from the net and protected from dust (this way you will avoid accidents
and will extend its working-life).

Installation

The UV-Visible Zuzi Spectrophotometer consists of the spectrophotometer's main unit

and, as an option, a HP jet-printer (like HP6000). The connections between them are
shown in the following figure.

- Items (1) and (2) are electric current connection cables for equipment and printer. They

should be connected before plugging the equipment to the net, so as to avoid damages.

- Item (3) is the cable to connect the spectrophotometer to the printer. The end with a 25-

pin plug should be connected to the main unit, whereas the one with a 36-pin plug should
be connected to the printer.

Connect all the cables by firmly locking the screws (if there is any) on the plugs. Please

make sure you connect it to a power supply of AC220V 50Hz ±10%.

Picture 5 - Installation

Note:

The spectrophotometer is a precision electronic instrument. Do plug/unplug the

cable when the instrument is switched on, otherwise it will provoke damages on the ins-
trument and the printer.

Switching on the equipment

First of all, you should check light

does not leak into sample compartment.
Then, you should turn on the power
switch of the main unit and then the
printer (2.4). The initializing page will
be displayed on the LCD (1.2). The ins-
trument starts self-checking and initiali-
zing. This process can take about 3
minutes. After initializing, the system
displays the instrument main menu.
