• Never ground yourself when taking measurements. Do not
touch exposed metal pipes, outlets, fixtures, etc., which
might be at ground potential. Keep your body isolated from
ground and never touch exposed wiring, connections, test
probe tips, or any live circuit conductors.
• Do not operate the instrument in an explosive atmosphere
(flammable gases, fumes, vapor, dust).
• Do not use this or any piece of test equipment without
proper training. Read the operating instructions before use
and follow all safety instructions.
• Use the meter only as specified in this manual; otherwise the
meters safety circuitry may not protect you.
• Use extreme caution when working around bare conductors.
Contact with the conductor could result in electric shock.
• The ridge at the top of the clamp body is intended to keep
hands and fingers away from hazardous live conductors.

The AD40B is an average sensing and RMS (sine wave) indicating
AC current clamp. The AC40C is an average sensing and RMS
(sine wave) indicating AC current clamp meter that also
measures AC and DC voltage, resistance and continuity.

Unpacking and Inspection

Your shipping carton should include the digital clamp meter ,
a carrying case, two 1.5 V AAA (UM-2) batteries (installed), and
this manual plus one test lead set (one black, one red) for the
AC40C meter. If any of the items are damaged or missing, return
the complete package to the place of purchase for an exchange.

AC CURRENt MEASUREMENt (FIg. 1)

1. Set the slide switch to AC
2. Open spring-loaded clamp by pressing lever on left side of
meter.
3. Position clamp around wire or conductor and release clamp
lever. Make sure that the conductor is centered in the clamp
and that the clamp is entirely closed. The clamp must be
positioned around only one conductor. If it is placed around
two or more current carrying conductors, the reading is
FALSE.
4. Read the measured value on the display. If the measured
value exceeds the highest range for a period of time,
overheating may occur. Interrupt measurement.
