will also cause the flow meter to advance to the next Program
step. If you select VOLUME for sampler pacing, the following
will appear:
SAMPLER PACING
ENTER PACING VOLUME XX.XXXX CF
• Other units of measure may appear here. The range for
pacing is max. flow divided by 100 (minimum) or 10,000
times max. flow (maximum.)
If Flowlink appears for sampler pacing, the operation of sampler
pacing has been determined by choices made in Flowlink, Isco's
proprietary data acquisition and storage software. Flowlink con-
trols the flow meter remotely, via phone lines and a modem, or
locally with a laptop computer and cable. In any event, if the
sampler pacing definition is controlled by Flowlink, it can only be
changed through Flowlink.
If you select CONDITIONAL for sampler pacing, the following
will appear:
CONDITION
• (LEVEL) • • (VELOCITY)• •(FLOW RATE) • • (RAINFALL) •
(DO), (pH), (TEMPERATURE), (YSI pH), (YSI DO), (YSI CON-
DUCTIVITY) and (YSI TEMP) may also appear. Note that all the
conditions shown above are in parentheses. Which ones actually
appear depends on your previous programming selections. At
least one of these options will be available to you.
Pressing the right arrow key may be necessary to bring all
items onto the display, provided they are available for use.
LEVEL will only appear if the flow meter is set up to measure
level or flow.
RAINFALL, D.O., pH, and TEMPERATURE measurement
require the appropriate sensor probe be used with the flow meter.
Remember that only one parameter condition (D.O. or pH) can be
measured by the flow meter at a time, unless you use the YSI 600
Sonde.
RAINFALL can appear if you have a rain gauge attached to the
flow meter.
TEMPERATURE can be measured alone, or with either
parameter.
D. O. and/or pH may not appear on the menu, depending on
selections made in step 1. If you do not see the item you need,
return to step 1, and recheck your programming. If you did not
make the proper selections there, certain menu options will not
appear here, as they would have been locked out.
The YSI 600 conditions of pH, DO, CONDUCTIVITY, and TEM-
PERATURE will only appear on the menu if you have turned
them on in steps 1 and 3.
