LANGUAGE may not appear on your machine. This is intended
primarily for export models, as they are programmed in different
languages. Domestic models contain only English.
If you select SET CLOCK, the following will appear:
Enter the year (four digits), the month (01-12), the day (01-31),
the hour (01-24), and the minute (01-59).
If you select SITE ID, the following will appear:
You can select any suitable three-digit number for the site identi-
fication.
If you select MEASUREMENT SETUP, the following will appear.
You will have to use the right arrow key to bring all the options
on screen:
-ERVAL is just off the screen. LEVEL READING INTERVAL
refers to how often the flow meter takes a level reading. LEVEL
refers to the level in the flow stream.
DO/PH READING INTERVAL refers to the measurement of spe-
cific aspects of the flow stream other than amount. 4220 Flow
Meters support measurement of three different characteristics:
temperature, pH (the relative acidity or alkalinity of a solution),
and D.O., dissolved oxygen.
Note
If you are using the Isco D.O. sensor or are sensing D.O. with
the YSI 600 Sonde, select as long a measurement interval as
is practical for your application. The reasoning is that the D.O.
sensor is turned off between measurement intervals and this
turned-off period prolongs the life of the sensor.
