Direct Transmission (Depths 2-12) Readings
Direct Transmission (Depths 2-12) readings require the gauge to be positioned
such that the void between the source rod and the inside of the ValiDator block
is minimized. Slide the gauge back until you can drop the source rod in the hole
on top of the ValiDator. Once the source rod drops in the hole, make sure to
keep the gauge flush with the left stop and slide the gauge back away from the
top stop until it can’t be moved any further.
