Campbell Scientific PST3/PST8 Pump and Slug Test System - Manual (Page 3)

1-1
SECTION 1. HARDWARE
The PST is a complete datalogging system for pump and slug tests. The PST3 can measure up to 3
wells and the PST8 up to 8 wells. This manual consists of 2 major parts. The first part, consisting of
Sections 1, 2, and 3, contains the basic information required to operate the PST. Section 3 is a prompt
sheet to be carried into the field. It leads a user step by step through the procedure for running a test.
The second major part, Sections 4 and 5, is a reference section containing more detailed information.
NOTE: This is the ONLY manual you'll need if you use the PST for pump and slug tests. For other
applications the CR10 and PC208 manuals will apply.
The PST is a complete system including both
hardware and software. The heart of the
system is the datalogger, the CR10
Measurement and Control Module (CR10).
The system is pre-wired, contains a
rechargeable power supply and is mounted in a
sealed case. The following pages depict and
explain the PST hardware. Please review the
following diagrams to familiarize yourself with
the system.
Figure 1.1 shows a field setup with a "cutaway"
view of the well with a pressure transducer
installed. See Figure 1-3 for details on the
pressure transducer installation.
The vent tube in the pressure transducer cable
terminates in the DES1 junction where the air is
dry and vented to atmosphere. Unvented cable
continues to the circular connector on the PST
case. Figure 1-2 shows case details while
Figure 1-4 shows cabling options to bring 12
volts DC to the PST to back up or change the
battery.
