One-Person Background Signal Strength Check (No Transmitter)
Roll/Pitch Check
At the end of the bore path, turn the receiver to face toward the launch end, and install
batteries in the transmitter to turn it on. Have a coworker hold the transmitter and stand
beside you approximately 1.5 times the maximum depth of your intended bore. Walk together
in parallel back toward the launch end, keeping the separation distance constant. Periodically
stop and have your coworker change the transmitter’s pitch and roll orientation so you can
verify the speed and accuracy of these readings on the receiver. Note any locations where
the display information becomes erratic or disappears.
Two-Person Roll/Pitch Test with Transmitter
Note Electrical interference is determined by observing the signal strength with
the transmitter turned on and then with the transmitter turned off. If the
difference between these numbers is less than 150, the electrical
interference is excessive.
