Teledyne 6600 manual Allow warm-up for 1 hour

Part III Model 6600

4Turn on utility power using circuit breaker switch to systems.

5Turn 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:

aSwitch 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

1Perform a self-diagnostic check of the Control Unit as indicated under Section 3.3.4 of the manual.

2Refer to Section 2.3, Part I, for Testing of System on Control Unit.
