combination of these conditions. The YSI 600 Sonde provides several measurements at the same time. You must have the appropriate sensors for rainfall, temperature, D. O., pH and the YSI outputs.

Note

2.3.7Step 7 - Alarm Dialout You must have the optional modem to make use of this pro-

	Mode	gram step. The menus will not even appear unless the flow
		meter has a modem installed.
		This feature allows you to program a 4200 Series Flow Meter to
		signal a remote location through a telephone line. The Alarm
		Dialout feature is useful if you need to signal a remote location
		when there is a change of condition in the flow stream that could
		constitute an alarm. You can program as many as five different
		eighteen-digit telephone numbers into the flow meter in
		decreasing order of importance. The modem is capable of speech.
		DISABLE inhibits this function altogether. CONDITIONAL
		lets you program the flow meter to signal these alarms for a
		variety of reasons. You can use rainfall, time, level, flow rate, dis-
		solved oxygen, pH, rate-of-change, a combination of conditions,
		or define the operation through Flowlink software from another
		computer. STORM lets you set the alarm through a combination
		of rainfall and time. You can also program the interval between
		calls and set up the system to reset the alarm condition by
		dialing back from the remote telephone.
2.3.8	Step 8 - Printer	All 4220 Flow Meters have a built-in printer. The printer is more
		than just a printer, as it is capable of plotting linear data along
		with printing alphanumeric (letters and numbers) messages. In
		this step you set the speed for the chart to advance, from 1/2" to
		4" per hour. Chart speed is set according to the amount of reso-
		lution you want to see on the chart. If there is much activity on
		the chart, you would generally choose a faster speed so the marks
		are more “spread out” and are easier to interpret. If there is little
		activity on the chart and you want the flow meter to run for long
		periods without having to change the chart paper roll, you would
		probably pick a slower speed.
		The flow meter is capable of plotting three separate data lines on
		the chart in addition to the alphanumeric messages. These lines
		may indicate various things, such as level, flow rate, pH, dis-
		solved oxygen, or temperature. Note that you must have the
		appropriate sensors for pH, DO, and temperature to make use of
		these plots. Rainfall is printed as a bar-graph. The printer is
		capable of plotting over-ranges for the data lines it plots. You can
		tell when the printer is in over-range if a data line goes off the
		chart on the right side and then immediately starts over again
		plotting on the left side.
2.3.9	Step 9 -	This step lets you program the flow meter to print out regular
	Reports/History	reports on the internal printer. The reports the flow meter prints
		are a summary of activity the unit records over a period of time.
