INTRODUCTION
1.1 INSTRUMENT DESCRIPTION
The Model 6300 is a microprocessor controlled Visible Range Spectrophotometer covering the wavelength range of 320 to 950nm with a 10nm bandwidth. The monochromator is of a modified Czerny Turner
design, incorporating a stepper motor driven 1200 lines/mm holographic diffraction grating and featuring
automatic second order response suppression. The 6300 has full interfacing capability for Analogue output
and serial (RS232) interfacing. The optical system is independantly housed and isolated with lenses to give
maximum protection from environmental contamination. Combined with a mechanically rigid structure, the
6300 provides a system with fast warm-up, low drift and high reliability.

INSTALLATION
2.1 UNPACKING
Remove the Model 6300 from the packaging and ensure the following items are present:
1. Model 6300 Spectrophotometer
2. Mains Cable
3. Pack 100 disposable Cuvettes (060 084)
4. Optional Accessories (as ordered)
Any shortages or damage should be reported immediately to the Manufacturer or your local
Distributor.
2.2 INSTALLATION
MAINS SUPPLY
The 6300 is designed to operate on 115/230V a.c. supplies (-20%+10%) 50/60Hz.
The standard 2 metre mains cable supplied with the unit is fitted with an IEC type connector which can be
plugged directly into the POWER IN socket on the rear panel.
The mains fuse is housed within the POWER IN socket. When replacing the fuse the unit should be
disconnected from the mains supply.
In the event of the fuse failing after replacement it is advisable to consult with the Manufacturer or your
local Distributor before proceeding further.
Fuse Rating: 2A 'F' (fast blow type)
NOTE: The unit should be positioned within 1.5 metres of an earthed mains supply.
VOLTAGE SELECT
NOTE: When changing the voltage select switch position always ensure the fuse rating
is correct.
Before attempting to change the voltage select disconnect the instrument from the mains supply. Withdraw
the fuse holder from the power input socket and remove the fuse. Extract the grey fuse retainer and rotate
so that the correct voltage is visible through the aperture in the fuse holder. Replace the fuse retainer in its
holder, fit the correct fuse and push assembly back into the power input socket.
MAINS CONNECTIONS
A suitable plug should be connected to the 3 wires on the mains lead. These are colour coded to conform
to the internationally recognised standard such that:
BROWN LIVE
BLUE NEUTRAL
GREEN/YELLOW EARTH
IMPORTANT: THE UNIT MUST BE EARTHED.
The Green/Yellow wire in the a.c. supply cable must be connected to a properly grounded terminal.
