3700 Portable Samplers
Section 3 Programming Guidelines
Power – The sample event was initiated to compensate for a
missed sample which should have occurred while the sampler
was without power. If more than one sample was missed, only
one sample will be taken.
Enable – The sample event was initiated when the sampler
became enabled by a device connected to pin F of the flow meter
connector, generally a 4200 Series Flow Meter, a 4100 Series
Flow Logger, or Liquid Level Actuator. This source is also
reported when the sample was initiated at a programmed
resume time. Two different configure option settings control this
event: the Sample Upon Enable setting in the Enable Pin con-
figure option and the Sample at Resume setting in the Sampling
Stop/Resume configure option.
Manual – The sample event was initiated with the manual
sample key and was counted as one of the programmed sample
events.
Time Switch – The sample event was initiated at the pro-
grammed switch time. This event is controlled by the Sample at
Time Switch setting in the Flow Mode Sampling configure
option. This option is available for flow-paced sampling only.
Disable – The sample event was initiated when the sampler
became disabled by a device connected to pin F of the flow meter
connector, generally a 4200 Series Flow Meter, a 4100 Series
Flow Logger, or a Liquid Level Actuator. This source is also
reported when the sample was taken at a programmed stop time.
Two different configure option settings control this event: the
Sample Upon Disable setting in the Enable Pin configure option
and the Sample at Stop setting in the Sampling Stop/Resume
configure option.
