 Warnings and Precautions

This instrument is EN61010-1:2001 and EN61010-2-32 • certiﬁed for Installation Category III. It is recommended for use with local level power distribution, appliances, portable equipment, etc, where only smaller transient overvoltages may occur, and not for primary supply lines, overhead lines and cable systems.

This instrument must not be used on uninsulated conductors • at a voltage greater than 600V ac/dc.

Use extreme caution when working around bare conductors • and bus bars.

Do not exceed the instrument overload limits per function • (see speciﬁcations) nor the limits marked on the instrument.

Exercise extreme caution when: measuring voltage >60 V • DC or 30 V AC RMS // current >10 mA // AC power lines with inductive loads // AC power lines during electrical storms // servicing CRT equipment. High voltages can be lethal and high voltage transients may occur at any time.

Never measure current while test leads are inserted in the • input jacks.

Always inspect your instrument, test leads and accessories for • signs of damage or abnormality before every use. If abnormal conditions exist (broken or damaged test leads, cracked case, display not reading, etc.), do not use.

When making voltage measurements, make sure these • ranges function correctly. Take a reading of a known voltage ﬁrst.

Application around and removal from hazardous live conductors is permitted

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.

INTRODUCTION

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)

Set the slide switch to AC1. B position. Open spring-loaded clamp by pressing lever on left side of 2.

meter. Position clamp around wire or conductor and release clamp 3.

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.

Read the measured value on the display. If the measured 4. value exceeds the highest range for a period of time, overheating may occur. Interrupt measurement.

Note Do not measure current on high-voltage conductors (>600 V) in

order to avoid risk of discharge and/or incorrect reading.

AC & DC VOLTAGE MEASUREMENT (AC40C) (FIG. 2)

Connect the black test lead to the COM input and the red 1. test lead to the “+” input.

Set the selector switch to V 2. C position. Press the AC DC button to select AC or DC voltage (3. B or F is

displayed). Connect probe tips to circuit, in parallel to the load.4. Read the measured value on the display.5.

RESISTANCE & CONTINUITY MEASUREMENT (AC40C) (FIG. 3)

Remove any voltage from resistance to be measured and 1. discharge all capacitors.

Connect the black test lead to the COM input and the red 2. test lead to the “+” input.

Set the selector switch to 3. Ω R position. Connect the probe tips across the circuit or resistance.4. Read the measured value on the display.5.

The instrument emits a continuous tone and the R symbol is displayed when the measured resistance is < 40 Ω.

DISPLAY HOLD

Press the HOLD button to keep the measured value on the display for later viewing. Press HOLD again to release the “Display Hold” function before taking a new measurement. Display Hold can be applied to all measuring functions.
