4.8.1 Change Measure Wait Time
The “measure wait time” is the time, in seconds, between the
start of a sample and the time the unit completes and datalogs a
measurement. The unit is preprogrammed to wait the optimum
amount of time, based on the type of tube being used. Each
tube type can be programmed separately. The user may want to
adjust this time in special situations. For example, when using
longer tubing to collect a remote sample (see Technical Note
140), longer times at low temperatures and shorter times at high
temperatures (see tube Data Sheets). Care must be taken when
setting this parameter because the final measurement value
depends on it. The minimum time is 10 seconds (time for UV
lamp to stabilize), and the maximum time is 255 seconds (4.25
minutes). For VOC tube measurements, this time is used only
during calibration; during normal VOC measurements the
readings run continuously until the user manually ends the
measurement.
