If the value is over the upper
limit, the operational
amplifier needs to be
modified.
When using a micro cell Modification is unnecessary.

7.1.3.2 Procedure to check the light intensity
(1) Attach a new D2 lamp and light it up.
(2) Fill the flow cell with deionized water
(3) Set the wavelength to 220 nm.
(4) Check light intensities SE/RE. If the value is over the standard value, lower
the gain of the pre-amplifier (PB-1 ASSY) by the procedure described below.
Modification is unnecessary if the light intensity is under the upper limit.
