4. MAINTENANCE AND TROUBLESHOOTING
4.1 Operational Check
Check the operation when the instrument has been installed.
(1) Prepare the instrument for operation as instructed in this
manual.
(2) Turn on the power switch of the detector.
(3) Check that measurement conditions (time constant, output
range, etc.) can be properly set.
(4) Check the wavelength operation by pressing
WL
key.
(5) Check the auto zero operation by pressing
A/Z
key.
4.2 Performance Checks
Check the performance when the instrument has been installed.
NOTE
:
First adjust the xenon lamp position (see 5.2.1 (3)) and
then check the performance. Positional adjustment of
the lamp is necessary for an accurate performance
check.
NOTE
:
When this detector unit is used in combination with
Hitachi Chromaster control option, the lamp energy,
wavelength accuracy and sensitivity can be
automatically calculated. For details, refer to the
instruction manual of Hitachi Chromaster control option.
4.2.1 Xe lamp energy check
Check the energy value of the Xe lamp at a wavelength of
254 nm (see section 3.3.7).
NOTE
: When the energy value of the Xe lamp has decreased
by 50% or more in comparison with the value at the
start of use, the useful life of the lamp is considered to
have expired. Use the decrease in energy value plus
baseline fluctuation (data variation or noise) in judging
the lifetime of the lamp.
