The liquid sensor on the sampler offers unparalleled sample accuracy and
repeatability. For most site conditions, no volume calibration is necessary, and
the volume collected is accurate within 10% of the requested volume. To
improve volume accuracy to 5%, or when sample volume accuracy is
adversely affected by unusual site conditions (such as the sample source
located higher than the sampler pump), or when the liquid sensor is disabled,
then volume calibration should be performed.
Sensor Disabled
When the sensor is disabled, you must calibrate the sample volume(s). If
more than one volume is programmed (such as when using storm water or
upset sampling), you must calibrate each volume independently (see chart
below).
