Batteries installed
backwards or no spring
contact Insure that positive terminals of both batteries (nub) face inward –
towards the black cap. Check that spring is attached to the battery cap.

EDXtreme does not appear
accurate Check installation &
system Insure that shackles are in good working condition and aligned straight.
Verify system is applying force directly through the dynamometer with no
off center or torsional loads being applied to the instrument.
Local gravitational
variances If being compared against dead-weights, check your local gravitational
constant. Use custom units to compensate or calibrate on-site.
Check repeatability Place EDX in low-resolution mode. Lift an arbitrary weight several times
as close to capacity as possible. Record each weight reading. Do the
readings differ from each other? Calculate the standard deviation of the
readings using a spreadsheet such as Microsoft Excel. See if the
deviation is greater than 0.1% of the instrument capacity.
Compare against a
reference load. Place EDX in low-resolution mode. Apply a known load near instrument
capacity. Check calibration date.
Radio communication
intermittent Low batteries. Distance
is excessive or dead-
radio pocket Bring remote closer to dynamometer. Allow several seconds to retrain.
Excessive radio noise or
interference in
environment Remove dynamometer and remote from the environment. Attempt
communications in an area free of local radio signals.
