SAFETY INFORMATION
The ACD-31P and ACD-41PQ Digital Clamp meters conform to EN61010-1:2001;
EN61010- 2-032:2002; CAT III 600 V, class 2 and pollution deg.2
This instrument is EN61010-1 certified for Installation Category III (600V). It is
recommended for use in distribution level and fixed installations, as well as lesser
installations, and not for primary supply lines, overhead lines and cable systems.
Do not exceed the maximum overload limits per function (see specifications) nor the
limits marked on the instrument itself. Never apply more than 600 Vdc/600 V ac rms
between the test lead and earth ground.
Warnings 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 Clampmeter, 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 fire 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 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/fingers behind the hand/finger 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 >1000 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.
CAUTION
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.

PEAK-rms Hold (see figure 2)
Peak-rms captures and displays the maximum RMS value of surge voltage or current with
durations as short as 65ms when in Vac or Aac.
Press and hold Peak-rms button for 2 beeps to enter this mode.
The LCD annuciators ‘P-‘ & ‘Max’ are turned on.
Press and hold Peak-rms button for 2 beeps to exit this mode.
HOLD (Data Hold)
Freezes the reading present on the LCD at the moment the button is pressed.
Set up the meter for the type of measurement desired.
Connect the test leads or clamp jaws to the circuit/component to be measured.
Press Hold button.
The LCD reading will freeze and display ‘‘. You may now remove the test leads and the
reading will not change until you press the Hold button again
Caution
Connection to a Hazardous Live circuit will still display the previous reading. This
function will not update the reading.
THD%-F (Total Harmonic Distortion-Fundamental) (see figure 3)
Fundamental distortion is the percentage ratio of the Total Harmonics RMS value to the
Fundamental RMS value of a voltage or current signal.
THD%-F = (Total Harmonics RMS / Fundamental RMS) x 100%
An ideal sinusoidal waveform has a value of 0.00 THD%. A highly distorted sinusoidal
waveform may have higher THD% value, up to several hundred.
Note: Used with Vac or Aac, THD%-F displays values up to 99 THD% in the secondary mini
display. Press THD%-F button to move THD%-F readings to main display to show readings
up to 999.9 THD%. Pressing THD%-F button will alternate the reading location.
SELECT / Backlight ()
Press Backlight button more than 1 second, enable/disable Backlight.
Press the SELECT / Backlight button to step through the manually selected V-A Auto
function options:
Auto →THD% Aac →THD% Vac →Vdc →Auto
Frequency (see figure 4)
Displays the line frequency when in Vac or Aac. Trigger levels vary with the ranges.
Press the ‘Hz’ button to display the signal frequency.
Press the ‘Hz’ again to return to previous display.
Auto Power Off function
The clamp meter powers down automatically after approximately 17 minutes of inactivity.
To turn it back on, move the function selector switch to OFF and back to a measuring
function.
To disable Auto Power Off, press and hold the HOLD button while moving the slide switch

to the desired function from OFF.
RS232C PC computer interface capabilities
The instrument is equipped with an optical isolated data output port at the back case
near the battery compartment. An optional PC interface kit RS232 KIT2 (Optical Adapter
Back, RS232 Cable and Amprobe Download Suite) is required to connect the meter to PC
computer thru RS232C protocol.
To enable the RS-232 output, press-and-hold the Hz button while sliding the function-
selector to a function.
The LCD displays ’ ‘ to confirm activation after the Hz button is released.
To disable the RS-232 output, slide the function-selector to any other position.
AutoVATM Measurement (see figures 5)
Select the AutoVA position.
With no input, the meter displays “Auto” when it is ready.
If no ACA current input via the jaws and a voltage signal > 2.4 Vdc or 30 Vac (40 Hz to
500 Hz) is present, the meter will display the voltage value with annunciator.
If no voltage signal is present on ‘+” COM terminals and a ACA current signal > 1 ACA
(40 Hz to 500 Hz) is present, the meter will display the current value and ~ A.
The Auto-VA feature stays at the auto-select function as long as its signal remains
above the specified threshold.
Press the SELECT button momentarily to manually step thru the functions (ACA →ACV
→DCV →Auto-VA).
Resistance Measurement (See Fig. 6)
Select the ‘ Ω‘ function .
Insert the test leads into the jacks. The red lead into V/Ω jack, and black lead into COM
jack.
Remove power from the circuit being tested and discharge all the capacitors.
Connect the test leads to the circuit, the resistance measured will be displayed.
If OL appears on the highest range, the resistance is too large to be measured.
Continuity Test (See Fig. 6)
Select the ‘' function.
Insert the test leads into the jacks, the red lead into V/Ω jack, and black lead into COM
jack.
Remove power from the circuit being tested and discharge all the capacitors.
Connect the test leads to the circuit,
The resistance will be displayed and the buzzer sounds when the resistance value is
between 10 and 300 Ω.
Temperature Measurement (see figure 7)

MAINTENANCE AND REPAIR
If there appears to be a malfunction during the operation of the meter, the following
steps should be performed in order to isolate the cause of the problem:
Check the battery.
Review the operating instructions for possible mistakes in operating procedure.
Inspect and test the test leads for a broken or intermittent connection.
Except for the replacement of the battery or test probes, repair of the multimeter
should be performed only by a Factory Authorized Service Center or by other qualified
instrument service personnel. The front panel and case can be cleaned with a mild solution
of detergent and water. Apply sparingly with a soft cloth and allow to dry completely
before using. Do not use aromatic hydrocarbons or chlorinated solvents for cleaning.
