Quick Check 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 Quick Check 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 Quick Check in low-resolution mode. Apply a known load near
instrument capacity. Check calibration date.
Radio communications not
working at all Dead batteries. Distance
is excessive, dead radio
pocket Bring remote closer to dynamometer. Allow several seconds to retrain.
Operating channels mis-
matched Remote and link must be on the same operating channel. See Quick
Check and Communicator configurations of COM1 for radio (under Comm
menu) and Common Configurations.
Excessive radio noise or
interference in
environment Remove dynamometer and Communicator from the environment. Attempt
communications in an area free of local radio signals. See Radio
Information section of the manual.
