ACA Current clamp-on function

Set the slide-switch function selector to the  position. Inputs are made

through the clamp jaws for non-invasive ACA current measurements.

CAUTION

• Press the jaw trigger and clamp the jaws around the hot conductor of a circuit

for load current measurement. Make sure the jaws are completely closed, or

else it will introduce measurement errors. Enclosing more than one conductor

of a circuit will result in differential current (like identifying leakage current)

measurement.

• Adjacent current-carrying devices such as transformers, motors and conductor

wires will affect measurement accuracy. Keep the jaws away from them as

much as possible to minimize inﬂuence.

6

Hi-Z DCV, ACV & Line-Level Hz functions

Set the slide-switch function selector to the position that selects common

impedance (Hi-Z) voltage measurements. Input impedance is set at

approximately 5MΩ to minimize loading on circuits under tests. DCV is

the default function. The DC symbol “” appears. Press SELECT button

momentarily to select ACV. The AC symbol “” a ppears. Press momentarily

again to activate the Line-Level Hz function.

Note:

• Line-Level Hz input sensitivity varies automatically with ACV range selected

when Line-Level Hz is selected. AC 6V range has the highest and AC 600V

range has the lowest sensitivity. Measuring the signal in ACV function WHILE

selecting Line-Level Hz function in that ACV range automatically sets the

most appropriate sensitivity for higher voltage applications. This can avoid

electrical noises as in 110/220V line voltage applications for example. If the

reading shows zero due to insufﬁcient signal levels, select Line-Level Hz

function BEFORE making measurements (at AC 6V range) will set the highest

sensitivity.

7

AutoTectTM mode

Set the slide-switch function selector to the position. This innovative

AutoTectTM feature automatically selects measurement function of DCV, ACV or

Resistance (Ω) based on the input via the test leads.

• With no input, the meter displays “Auto” when it is ready.

• With no voltage signal but a resistance below 6MΩ is present, the meter

displays the resistance value. When below 25Ω (0.025kΩ) is present, the meter

also gives a continuity beep tone.

• When a signal above the threshold of +1.5 VDC, -1 VDC or 2 VAC up to the

rated 600V is present, the meter displays the voltage value in appropriate DC

or AC, whichever larger in peak magnitude.

• Overload-Alert Feature: When above rated 600V is present, the meter displays

“OL” with a warning beep tone for over-range indication. Disconnect the test

leads from the signal immediately to avoid hazards.

8

Note:

• Range-Lock Feature: When a measurement reading is being displayed in

AutoTectTM mode, press the RANGE button momentarily 1 time this locks the

function-range it is in. The symbol “ Auto”disappears. Range-lock can speed

up repetitive measurements. Press the button momentarily repeatedly to

step through the ranges. Press and hold the button for 1 second or more to

resume AutoTectTM mode.

• As Hazardous-Alert: When making resistance measurements in AutoTectTM

mode, an unexpected display of voltage readings alerts you that the object

under test is being energized.

• Ghost-voltage buster: Ghost-voltages are unwanted stray signals coupled

from adjacent hard signals, which confuse common multimeter voltage

measurements. Our AutoTectTM mode provides low (ramp-up) input

impedance (approx. 1.6kΩ at low voltage) to drain ghost voltages leaving

mainly hard signal values on meter readings. It is an invaluable feature for

precise indication of hard signals, such as distinguishing between hot and

open wires (to ground) in electrical installation applications.

WARNING:

• AutoTectTM mode input impedance increases abruptly from initial 1.6kΩ to

a few hundred kΩ’s on high voltage hard signals. “LoZ” displays on the LCD

to remind the users of being in such low impedance mode. Peak initial load

current, while probing directly to 600VAC for example, can be up to 530mA

(600V x 1.414 / 1.6kΩ), decreasing abruptly to approx. 4mA (600V x 1.414 /

210kΩ) within a fraction of a second. Do not use AutoTectTM mode on circuits

that could be damaged by such low input impedance. Instead, use slide-switch

function selector common input impedance voltage modes (Hi-Z of approx.

5MΩ) to minimize loading for such circuits.

Manual or Auto-ranging

When the function selected has more than one range, press the RANGE button

momentarily selects manual-ranging. The meter remains in the range it was in.

The LCD symbol Auto disappears. Press the button momentarily again to step

through the ranges. Press and hold the button for 1 second or more to resume

auto-ranging.

Note:

*Manual-ranging feature is not available to 600Ω/ •/ functions.

*To use Manual-ranging feature in AutoCheckTM mode, please see “Range-Lock

Feature” as explained in footnotes of AutoCheckTM mode section.

AC Voltage Detection - VolTectTM

At any function, press the EF (NCV) button momentarily to toggle to AC

Voltage Detection, VolTectTM. The meter displays “ ” when it is ready. Signal

strength is indicated as a series of bar-graph segments on the display plus

variable beep tones.

• Non-Contact EF-Detection (NCV): An antenna is located along the top of

the stationary jaw (See symbol on the jaw), which detects electric ﬁeld

surrounds current-carrying conductors. It is ideal for tracing live wiring

connections, locating wiring breakage and to distinguish between live or

earth connections.

• Probe-Contact EF-Detection: For more precise indication of live wires, such

as distinguishing between live and ground connections, use the Red (+) test

probe for direct contact measurements.

10

600Ω/ •/ functions

Set the slide-switch function selector to the 600Ω/ •/ position.

• 600Ω Resistance range with Audible-Continuity is the default function.

It is an extended low resistance range to complement the Resistance (Ω)

function in AutoCheckTM mode. Audible-Continuity response time is also

improved drastically (from that of AutoCheckTM mode) under such stand-alone

range architecture. Audible-Continuity is convenient for checking wiring

connections and operation of switches. A continuous beep tone indicates a

complete circuit.

• Press SELECT button momentarily selects Diode test function. The display

shows the approximate voltage drop across the test leads. When forward

biased, normal forward voltage drop for a good silicon diode is between

0.400V to 0.900V. A reading higher than that indicates a leaky diode

(defective). A zero reading indicates a shorted diode (defective), and the

meter gives a continuous beep warning. An OL indicates an 10 open diode

(defective). Reverse the test leads connections (reverse biased) across the

diode. The display shows OL if the diode is good. Any other readings indicate

the diode is resistive or shorted (defective).

11

• Press SELECT button momentarily AGAIN selects Capacitance function.

Capacitance measurement time varies with capacitance value. Only a few

seconds is required for measuring values of below 100μF. However, one

minute or more is required for measuring extreme values of around 2000μF.

HOLD  feature

The Hold feature freezes the display for later viewing. Press the HOLD 

button momentarily to toggle to the Hold feature. The symbol “” appears.

Backlighted display (model ACD-15 TRMS Pro only)

Press the SELECT button for 1 second or more to turn on or off the display

backlight feature.

Auto Power Off (APO)

The meter turns off intelligently after approximately 3 minutes of neither

signiﬁcant measurement nor button/switch activity. To wake up the meter from

APO, press any button or turn the rotary selector to OFF and back on again.

Always turn the rotary selector to OFF when the meter is not in use.

MAINTENANCE

WARNING

To avoid electrical shock, disconnect the meter from any circuit, remove the test

leads from the input jacks and turn OFF the meter before opening the case. Do

not operate w ith open case.

Trouble Shooting

If the instrument fails to operate, check batteries and test leads etc., and

replace as n ecessary. Double check operating procedure as described in this

user’s manual. If the instrument voltage-resistance input terminal was subjected

to high voltage transient (caused by lightning or switching surge to the system)

by accident or abnormal conditions of operation, the series fusible resistors will

be blown (become high impedance, open) like fuses to protect the user and the

instrument. Most measuring functions through this terminal will then be open

circuit. The series fusible resistors and the spark gaps should then be replaced

by qualiﬁed technician. Refer to the LIMITED WARRANTY section for obtaining

warranty or repairing service.

12

Cleaning and Storage

Periodically wipe the case with a damp cloth and mild detergent; do not use

abrasives or solvents. If the meter is not to be used for periods of longer than

60 days, remove the batteries and store them separately
