4230 Flow Meter
Section 2 Programming
2-29
If you are using either the pH or D.O. probe, temperature must
be measured; the NOT MEASURED option will not even appear.
The following menus concern the use of the YSI 600
Multi-Parameter Sonde. This probe allows you to measure
several characteristics of a flow stream at the same time. The
YSI 600 Sonde attaches to the Rain Gauge connector. This con-
nector must be a special connector with nine pins.
Note
4230 Flow meters with 4-pin Rain Gauge connectors cannot
support the YSI 600. It is necessary to return the flow meter to
the factory for modifications. There are also significant internal
modifications to the flow meter’s electronics and software.
You can use both the YSI Sonde and a Rain Gauge on flow meters
that support the YSI with a special Y-connect cable. The YSI 600
Sonde differs from the previously mentioned pH and D.O. probes.
The YSI 600 can measure pH and D.O. at the same time, as well
as temperature and conductivity.
If you are not using the YSI 600 sonde, select NO in the following
display and the flow meter will advance to the next step. Oth-
erwise, select YES.
• If you select NO, you will be unable to activate the YSI
Sonde later in the program.
If no communication has been confirmed, the following display
will appear:
NO is the default. If you select YES, the following display will
appear:
CAUTION
Do not disconnect either the sonde or flow meter power during
a communications check. The memory in the sonde can be
damaged by a power failure during an update.
If the communication check is bad, the following display will
appear:
