PREPARATION
CHOOSING A MULTIMETER
To use the probe, you must connect it to a suitable digital multi-
meter (RadioShack offers a wide variety of multimeters that
meet the following specifications).
Caution: The multimeter you select must:
• Be able to measure AC current equal to
1
/
2000
th of the cur-
rent in the wire to be measured.
• Have input jacks that are compatible with the banana plugs
on the probe’s test leads.
• Have an AC current range of 20 mA or greater, up to 200
mA.
• Have an input resistance of less than 12
Ω
in its AC current
mode.
Using a multimeter that does not meet these specifications
could damage the probe or the multimeter.
Important: The probe will not provide accurate readings if the
multimeter you connect it to is set to an AC current range of less
than 20 mA.
