6700 SAMPLERS
RUNNING PROGRAMS
To run a standard or extended program, select RUN from the
main menu. You may also select YES at the RUN THIS PRO-
GRAM NOW? screen at the end of the programming screens.
This is illustrated in Figure 11.
Extended programs scheduled to start at a clock time will not
start until the programmed clock time on or after the first valid
date.
Note that if you have recently calibrated a parameter probe, the
sampler may delay the start and display “PLEASE WAIT” until
valid readings are expected from the probe. The delay accounts
for the time typically required to install the probe, and lasts for
five minutes after you complete the calibration.
RUN TIME SCREENS
While running a sampling program, the sampler displays a variety
of messages that report the program’s status. For example, if
the sampler has not yet reached the programmed start time, it
displays the scheduled start time as well as the current time. (A
few common run time displays are illustrated in Figure 11.)
Once the program reaches the start time, you can determine the
time of the next sample, the next bottle to receive a sample, sample
distribution, and other information. Other messages appear
while the sampler runs through a sampling cycle as it takes a
sample. When the sampler needs to report multiple messages, it
alternates them, displaying each for one to three seconds.
Module and YSI Sonde Readings
Samplers with an attached module display the module’s readings:
pH and temperature for the pH module; percentage or flow
rate for the 4-20 mA module; level, flow-rate, and flow volume
readings for the flow modules; level, velocity, flow-rate, and positive
flow volume readings for the area velocity module. Some
module screens will alternate with the sampler screens.
Samplers with an attached YSI Sonde will display the parameter
readings selected during the YSI hardware setup. The YSI screens
alternate with the sampler and module screens.
