Safety Information

• The ACD-20SW, ACD-21SW and ACD-21SWC swivel Clamp meters conform

to EN61010-1:2001; EN61010- 2-032:2002; CAT III 600 V, class II; pollution

deg.2 and EN61326-1 (EMC compliance)

• This instrument is EN61010-1 certied for Installation Category III (600V).

It is recommended for use in primary supply lines, overhead lines and

cable systems and distribution level and xed installations, as well as lesser

installations.

• Do not exceed the maximum overload limits per function (see

specications) nor the limits marked on the instrument itself. Never apply

more than 600 V ac rms between the test lead and earth ground.

WWarnings and Precautions

• Before and after hazardous voltage measurements, test the voltage

function on a known source such as line voltage to determine proper

meter functioning.

• Disconnect the test leads from the test points before changing meter

functions.

• Disconnected from the meter’s test leads before measuring current.

• Inspect the Clamp meter, test leads and accessories before every use. Do

not use any damaged part.

• Never ground yourself when taking measurements. Do not touch exposed

circuit elements or test probe tips.

• Do not operate the instrument in an explosive atmosphere.

• To reduce the risk of re or electric shock, do not expose this product to

rain or moisture.

• The meter is intended only for indoor use. To avoid electrical shock hazard,

observe the proper safety precautions when working with voltages above

60 VDC, 42.4 Vpk, or 30 VAC rms. These voltage levels pose a potential

shock hazard to the user.

• Before and after hazardous voltage measurements, test the voltage

function on a known source such as line voltage to determine proper

meter functioning.

• Keep your hands/ngers behind the hand/nger barriers (of the meter and

the test leads) that indicate the limits of safe access of the hand-held part

during measurement.

• Inspect test leads, connectors, and probes for damaged insulation or

exposed metal before using the instrument. If any defects are found,

replace them immediately.

• This Clamp-on meter is designed to apply around or remove from un-

insulated hazardous live conductors. Individual protective equipment must

be used if hazardous live parts of the installation could be accessible.

• Exercise extreme caution when: measuring voltage >20 V // current >10

mA // AC power line with inductive loads // AC power line during electrical

storms // current, when the fuse blows in a circuit with open circuit voltage

>600 V // servicing CRT equipment.

• Remove test leads before opening the case to change the battery.

• Disconnect circuit power and discharge all high-voltage capacitors before

testing resistance, continuity, diodes, or capacitance.

• To avoid false readings, which could lead to possible electric shock or

personal injury, replace the batteries as soon as the low battery indicator

( ) appears.

• To avoid electric shock hazard, do not use the HOLD mode to determine if

a circuit is live. Unstable readings will not be captured and displayed.

WCAUTION

For non-invasive ACA current measurements, clamp the jaws around only

one single conductor of a circuit for load current measurement. More than 1

conductor will cause false readings

INTRODUCTION

The ACD-20SW, ACD-21SW and ACD-21SWC clamp-On meters come with a new

patented rotating head design that allows easy viewing of the measurements in

tight or inconvenient to reach places. Simply rotate the body of the meter to get

an unobstructed view of the LCD display. Rich set of features and CAT III 600V

safety reading for use in electrical and HVAC applications.

The features include:

•180 degree rotating head for the perfect display viewing

•Advanced VoltTect non-contact voltage detection

•Slim jaw design with one hand operation

•Measures AC Current up to 400 ACA, AC/DC Voltage up to 600V,

•Resistance and Capacitance(ACD-21SW / ACD-21SWC only)

•Temperature measurement (ACD-21SW / ACD-21SWC only)

•Audible continuity

•Auto and manual ranging respectively for quick checks and precise

measurements

•Auto power off

•Data hold

•Diode Test (ACD-20SW only)

•Accommodates conductors up to 1.18” (30mm) in diameter

OPERATION

HOLD Button

Data hold freezes the reading present on the LCD at the moment the button is

pressed.To use this menu feature, set up the meter for the type of measurement

and range desired.

Connect the test leads to the circuit / component to be measured and then press

“HOLD” push button. The LCD reading will freeze and display “HOLD.” You may

now remove the test leads and the reading will not change until you press Hold

again.

RANGE Button

This function allows the user to select the range of a function that does not show

‘RANGE’ on the LCD.

Measuring DC Voltage

1. Set the Function Switch to L

2. Connect the test leads: Red to +, Black to COM.

3. Connect the test probes to the circuit test points. Refer to Fig.1

4. Read the display. If necessary, correct any overload ( 0L) conditions.

Measuring AC Voltage

1. Set the Function Switch to K.

2. Connect the test leads: Red to +, Black to COM.

3. Connect the test probes to the circuit test points. Refer to Fig.2

4. Read the voltage on the primary display and the frequency on the

secondary display. If necessary, correct any overload (0L) conditions.

AC Current Measurement

1. Set the Function Switch to position ?.

2. Open spring-loaded clamp by pressing the jaw opening lever on the left

side of meter.

3. Position clamp around one wire or conductor. Release the jaw opening

lever. Wire should be center inside the jaws. Refer to Fig.3

4. Read the current on the primary display and the frequency on the

secondary display. If necessary, correct any overload (OL) conditions.

Capacitance Measurement (ACD-21SW / ACD-21SWC only)

When testing a capacitor that is part of a circuit, if “dS.C” is displayed on the

screen, a voltage is present. Discharge the capacitor before testing.

1. Sett the Function Switch to “ E” position.

2. Connect the test leads: Red to +, Black to COM.

3. Connect the test probes to the circuit test points. Refer to Fig. 4

4. Read the display. If necessary, correct any overload (0L) conditions.

WCAUTION

Using the Resistance or Continuity function in a live circuit will produce false

results and may damage the instrument. In most cases the suspected component

must be disconnected from the circuit to obtain an accurate reading.

Resistance

1. Set the Function Switch to e. Use the “e/R“ button to select the

resistance test (ACD-21SW / ACD-21SWC only).

2. Connect the test leads: Red to +, Black to COM.

3. Turn off power to the circuit being measured. Never measure resistance

across a voltage source or on a powered circuit.

4. Discharge any capacitors that may inﬂuence the reading.

5. Connect the test probes across the resistance. Refer to Fig.5

6. Read the display. If 0L appears on the highest Range, the resistance is too

large to be measured or the circuit is an open circuit.

Continuity Testing

1. Set the Function Switch to e. Use the “e/R“ button to select the test

(ACD-21SW / ACD-21SWC only).

2. Connect the test leads: Red to +, Black to COM.

3. Turn off power to the circuit being measured.

4. Discharge any capacitors that may inﬂuence the reading.

5. Connect the test probes across the resistance or the two points of test

6. Listen for the tone that indicates continuity (< 25e).
