The performance verification procedure requires the test equipment or
equivalent listed in the following table If different equipment is
substituted, control settings or test equipment setup may need to be
altered.
The performance verification consists of an accuracy check of the
probe ranges.
Warm up the test equipment at least 20 minutes to stabilize it before
performing the checks.

CAUTION.
Magnetic fields are produced that can cause a malfunction
in heart pacemakers, or damage to sensitive equipment. To avoid
malfunctions, it is not recommended to make a coil with more than
100 turns. Coil currents in excess of 0.2 Amperes are not
recommended.
For the accuracy check you will need a simple current loop. Wind
