Leaving The Cd42 Unattended - CDI CD42 Instruction Manual

CD42 Pipeline Pig Location & Tracking System

Leaving the CD42 Unattended

If the CD42-R is set up to record in Automatic mode, it can be used to detect pigs in an unattended
fashion. This might be useful if an operator simply wanted to know if a pig, or any number of pigs,
passed a certain location in the middle of the night.
To accomplish this, place the CD42-R receiver in the location to be monitored. Be sure the CD42-R is
in Automatic record mode (Figure 80). The CD42-R will turn itself on and automatically begin
recording when it detects a valid pig passage. When the operator returns to check the CD42-R, the
display will verify how many pig passages have been recorded. The time of the recording can also be
displayed in the File Menu. Refer to the section titled "File Menu" on page 23 for information on
viewing and manipulating File Recordings.
