4 Turn on utility power using circuit breaker switch to systems.
5 Turn on bypass pump when applicable, and assure back-pressure
regulator or recirculation loop around pump is OK for its protection.
Allow 10-30 minutes of flushing inlet bypass while observing the water
outlet to drain cleanliness.
7 Once assured sample inlet is proceed as follows:
a Switch on V1 using the sample/utility valve set to
utility position with the same V1 open Observe the cleanliness of the
utility water to the drain. (You can again also check water quality at the
sample grab point).
If clear, then turn on Sample pump using sample pump power
(which also turns on the homogenizer when applicable (application
dependent) Allow several minutes for the sample to flush through the
entire measuring train of the system to drain or safe vent.
8 Allow warm-up for 1 hour
The UV lamp in particular requires the most time to stabilize from a cold
start. If the unit has been turned of temporarily for only a few minutes, warm-up
can usually be reduced but observation of the output current or voltage should
be checked for stability of at least +/- 1% full scale range. During the initial
power-on the instrument performs an auto zero (autocal if span flag used) if
AUTOCAL functions are on, so stability should be observed after the hold/
tracking output has been
released (typically commences after 3 minutes when
power on). See Section 3.3.9 Hold/Track setup.
C Testing the system
A Control Unit
1 Perform a self-diagnostic check of the Control Unit as indicated
under Section 3.3.4 of the manual.
2 Refer to Section 2.3, Part I, for Testing of System on Control Unit.
3 Please refer to Section 3.0 for Setup parameters, operation, programming
of the Control Unit.
B Analysis Unit
