Optical path of the K–2600 UV detector
The light emitted from the lamp [1] is bundled and guided to a grating
monochromator [5] for defining the desired wavelengths. After passing
a filter [7] (optional) the beam is splitted by a semi transparent mirror [8].
One beam gives a reference signal [11], the other beam is guided
through the cell [9] where optical absorption is measured [10]. The
difference or the ratio of the two signals can be calculated.
Preparing the K–2600 UV detector for Operation
Unpacking
After unpacking, please check the device and accessories thoroughly
for any damage that may have occurred during transport. If necessary,
put forward any claim for damages to the carrier.
Use list “Standard delivery” on page 31 and check that the K–2600 UV
detector delivery is complete. Please contact our service department if
you miss something or if you need support. Please fill out the guarantee
registration card and return it to us immediately.
Power Supply, ON/OFF, Self Tests
The K–2600 UV detector is equipped with an universal power supply
which operates in the range from 90 to 260 Volts AC. A manual setting
of the supply voltage is therefore not required.
Make sure that mains power supply is properly grounded and a
correct three-pronged power cable is used.
Connect the power cable to the device and the socket, and then switch
the device on with the ON/OFF key, see [5.2] and [5.3] in Fig. 3 on page
8.
After switching on, the display, see 1 in Fig. 2 on page 8, is indicating
some information, such as
HPLC SPECTRAL PHOTOMETER
, and the
VERSION
of the internal Software, e.g.
1.07
.
The power-on selftest performed includes a check of the electronic
function, wavelength calibration, see „AUTO CALIBRATION“ on page
