2. Place the gauge on top of the standard block on
a level surface; the keypad end of the gauge
should be pushed against the metal butt plate.
See Fig 2.1.
3. Ensure the reference standard block is placed on
a dense material, such as soil, asphalt, or
concrete. Do not take standard counts on truck
tailgates, tables, or non-solid floors.
4. When you place the source rod in the “SAFE”
position notch, gently tap it down without pulling
the trigger to make sure the handle plunger is
properly seated inside the notch. Ensure the
handle is reasonably parallel with the gauge.
