Campbell Scientific PST3/PST8 Pump and Slug Test System - Manual (Page 19)

Correct the offset if necessary.
Ready to begin the test.
Turn the recording switch to the "ON" position at the same time the
pumps are turned on or the slug is inserted.
Logarithmic - data collection begins when the switch is turned to "ON".
Delta - the elapsed time starts when the switch is turned to "ON". In a
slug test the switch can be turned to "ON" just before the slug is intro-
duced. Data will be recorded as the water level changes.
Set the Recording switch to the "OFF" position.
At the end of the test the following will be recorded:
- the sensors' current readings
- the header line including location ID # and battery voltage.
DO NOT turn the power switch off until all data is collected into a PC or
the optional storage module. ALL DATA IN THE PST WILL BE LOST
WHEN POWER IS TURNED OFF.
