V
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 Autodisappears. 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 kΩs 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
Battery replacement
The meter uses standard 1.5V AAA Size (NEDA 24A or IEC LR03) battery X 2
Loosen the 2 captive screws from the battery cover case. Lift the battery cover
case. Replace the batteries. Replace battery cover case. Re-fasten the screws.
