Q:
A:
The MP TROLL 9500 rolled out of the back of my truck
and hit the ground pretty hard. It still talks. Is it OK to
use?
The instrument is pretty rugged, and can survive a few
drops and rolls. We hope the restrictor was on to protect
the sensors! First, check the joint between the body and the
restrictor. It should appear smooth and tight to preserve the
integrity of the water seal. Next, remove the restrictor and
insure the pressure sensor is snug against the sensor block.
Push it firmly into the sensor block if you see a gap. If the
temperature sensor is bent, straighten it gently but firmly by
hand (no tools, please).
If the instrument is dropped repeatedly on the nose cone,
check for damage to the batteries.
