4.6.2 Sampler
Enable/Disable
Teledyne Isco flow meters and flow loggers have a programmable
sampler-enable feature that lets them enable (start) or disable
(stop) a program according to certain monitored conditions. For
example these conditions can be level, flow rate, pH, temper-
ature, percent, rainfall, I/O; or a combination of two conditions.
The 1640 Liquid Level Actuator can also be used, as well as any
other instrument that can ground the input to pin F. Grounding
the input disables the sampler.
The sampler disregards disable signals during the delay to start
time. However, when the sampler detects a disable signal at the
start time, it suspends the program until it is enabled. The
diagram in Figure 4-2 shows the sampler’s responses.
