3700 Portable Samplers
Section 3 Programming Guidelines
3.18 Run State
3-106
Sampler Inhibited! – The sampler was prevented from taking
the sample by an inhibit signal sent to the sampler by a flow
meter or a liquid level actuator.
Distributor Jammed! – The sampler was unable to take the
sample because the distributor jammed.
Probable Overflow! – Overflow is determined by comparing
the bottle volume to the product of the sample volume and the
number of samples. If the product exceeds the bottle volume, the
sampler will not pump a sample for that sample event and will
record the "Probable Overflow!" message.
Float/Weight Tripped! – 3700 Samplers that are set up for
single-bottle compositing detect overflow with a liquid-level float
located at the mouth of the composite bottle. If the liquid level of
the bottle raises the float past the trip point, the sampler will
interrupt the sample event and record the "Float/Weight
Tripped" condition.
No More Liquid! – The sampler was unable to take the sample
because, in attempting to take the sample, the sampler pumped
all liquid from the flow stream.
No Liquid Detected! – The sampler was unable to take the
sample because no liquid was detected.
Sampler Shut 'Off'! – The sampler was unable to take the
sample because it was halted with the
sample event.
A sampler in the run state is executing the sampler's instructions
according to the settings you've entered in the program and con-
figure sequences.
To start a sampling program and place the sampler into the run
state, press the start sampling key. While running the sampling
program, the sampler will present several displays that allow
you to monitor the sampler's progress. The displays are listed
with a brief explanation in Examples: Run State Displays:
Time-Paced Sampling, Run State Displays: Flow-Paced Sam-
pling, and Run State Displays: Composite Sampling.
If you encounter a problem while running a sampling routine
that results in missed samples, an asterisk will appear in the
lower right corner of the display, as illustrated below.

There is one condition under which the sampler will enter the
run state after the start sampling key is pressed, but will not
begin the sampling program. If the sampler is interfaced with a
flow meter, liquid level actuator, or other equipment capable of
transmitting an inhibit signal, the sampler will not begin the
key during the
