AutoVATM Function
Set the slide-switch function-selector to the position.
• With no input, the meter displays “ ” when it is ready.
• With no ACA current input via the jaws but a voltage signal above the
nominal threshold of DC 2.4V or AC 30V (40Hz ~ 500Hz) up to the rated
600V is present on V-COM terminals, the meter displays the voltage
value in appropriate DC or AC, whichever larger in peak magnitude.
Annunciators “Auto” “dc” and “Auto” “
• On the contrary, with no voltage signal present on V-COM terminals
but a ACA current signal above the nominal threshold of AC 1A (40Hz ~
500Hz) up to the rated 600A is input via the jaws, the meter displays the
ACA current value. Annunciators “
• The Auto-VA feature stays at the auto-selected function as long as
its signal remains above the specified threshold. Press SELECT button
momentarily to manually select and lock (annunciator “Auto” turns off)
thru the functions ACA, ACV, DCV and then goes back to Auto-VA.
CAUTION
• For non-invasive ACA current measurements, press the jaw trigger
and clamp the jaws around only one single 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. Locate the conductor(s) at
the Jaws center as much as possible to get the best measuring accuracy.
For removal, press the jaw trigger and remove the jaws from the
conductor(s).
• 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.

Peak-rms Mode
Peak-rms compares and displays the maximum RMS value of surge voltage
or current with durations as short as 65ms. When ACV or ACA function is autoselected or manual-selected, press and hold Peak-rms
or more toggles to this mode. The annunciators “P-” “Max” turn on. APO
(Auto Power Off) feature is disabled automatically accordingly.
In ACA function, the Peak-rms mode starts at the highest 600A range to
maximize measuring dynamic range. Before making measurement, press
the Peak-rms
measuring dynamic range 400.0A or 40.00A for higher measuring resolutions.
button momentarily again can manually select thru lower
button for one second
Line-level Frequency (Hz) Function
When ACV or ACA function is auto-selected or manual-selected, press Hz
button momentarily toggles to Line-level Frequency (Hz) function. The Hz
trigger level is determined by the selected function-range from where the Hz
function is activated.
5
In ACA function, activating the Hz function during significant measurements
can get the most appropriate trigger level to avoid electrical noises in
most cases. Activating the Hz function at AC 40.00A range (before making
significant measurements) can get the lowest trigger level (highest sensitivity).
HOLD Mode
When any function is auto-selected or manual-selected, press HOLD button
momentarily toggles to Hold mode. The annunciator “
mode freezes the display for later viewing.
Notes on Displacement Power Factor & Total Power Factor
• Introduction: Power is the rate of change of energy with respect to time
(in terms of voltage V and current A). Instantaneous (real) power w = vi
where v is the instantaneous voltage and i the instantaneous current.
The average (real) power is the mean of vi and is given by:
W = ω/2π∫vi dt , over the interval from 0 to 2π/ω
• Displacement Power Factor (more traditional): Assuming V and A are
pure sinusoidal waveforms without harmonics (as in most traditional
cases), that is, v = V sinωt and i = I sin (ωt -θ), the expression can be
simplified to:
W = 1/2 x V x I x Cosθ where V and I are the peak values, θ is the
displacement power factor angle, and Cosθ is the displacement power
factor. Using RMS values, it is written as:
W = Vrms x Arms x Cosθ
Practically, in such cases without harmonics, θ is also called the phaseshift angle of the current A to the voltage V. An inductive circuit is said
to have a lagging power factor since current A lags voltage V (phaseshift angle θ and thus Sinθ are both “+”), and a capacitive circuit is said
to have a leading power factor since current A leads voltage V (phaseshift angle θ and thus Sinθ are both “-”).
• Total Power Factor (encountering harmonics): When encountering
distorted waveforms with the presence of harmonics, however, the
simplified power expression should not be used since substituting the
above mentioned pure sinusoidal V and A functions cannot fulfill the
actual conditions. Cosine of phase-shift angle (Cosθ), or the displacement
” turns on. Hold
6
power factor, is no longer the only component constituting the overall
power factor. Harmonics do increase apparent power and thus decrease
the overall power factor.
That is the Total Power Factor is actually affected by both phase-shift
angle and harmonics, and is given by the expression:
Total Power Factor (PF) = Real Power (W) / Apparent Power (VA)
In order to improve overall system power factor, nowadays power-system
engineer needs to address both phase-shift and harmonics problems.
Practically, harmonics should be dealt with (e.g. filtering out) before
phase-shift to be corrected (e.g. installing capacitors in parallel with
inductive loads).
7
Single-Phase Power & 3-Phase Balanced-Load Power Functions
Set the slide-switch function-selector to the “3~Bal • 1~” Power position.
• Default at last selected function.
• Press “3~Bal • 1~” button momentarily to toggle between “Single-
Phase” and “3-Phase Balanced Load” Power functions. Annunciators “
” and “3~” turn on respectively.
• Press SELECT button momentarily selects between W (real power), VAR
(reactive power), VA (apparent power) & kWHr (real-time readings or
stored result) functions. In W (real power), VAR (reactive power), or VA
(apparent power) function:
1. PF (Total Power Factor) is displayed automatically in the secondary mini
display.
2. Annunciator “A-lags-V” turns on to indicate an inductive circuit is
being measured. That is, the Current waveform is lagging the Voltage
waveform, and the phase-shift angle θ is “+”.
3. On the contrary, together with significant PF values, WITHOUT
“A-lags-V” being turned on indicates that a capacitive circuit is being
measured. That is, the Current waveform is leading the Voltage
waveform, and the phase-shift angle θ is “-”.
8
Note:
1. Under proper measurement setups for load circuits, the W (real power)
readings are always positive. Negative W readings indicate reversed
clamp-on jaws direction or test leads polarities, or even incorrect voltage
lines are being measured as in 3-phase measurement setups. Correct
them for proper “A-lags-V” indications.
2. When encountering largely distorted waveforms, “A-lags-V” detection
might be affected due to the influence of harmonics. It is recommended
to manage (e.g. filter out) harmonics problems before measuring/
dealing with phase-shift problems.

A-lags-V Indication:
LCD annunciator “A-lags-V” turns on to indicate an inductive circuit, or
Current A lags Voltage V (i.e., phase-shift angleθ is “+”).
A-lags-V Indication is specified at 50/60Hz fundamental without the presence
of harmonics, and at ACV > 90V, ACA > 9A and PF < 0.95

3-Phase Unbalanced-Load Power
This 3-Phase Unbalanced-Load Power measurement is achieved thru the
calculation of discrete single-phase measurements that are taken one at a time
manually. Since it is not real-time on all 3 phases simultaneously, it is intended
only for stable power conditions without significant power fluctuations over
the time of measurements. Result accuracy is hence the accumulated accuracy
of the discrete single-phase measurements plus the associated fluctuations.

MAINTENACE AND REPAIR
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 with open case.
Trouble Shooting
If the instrument fails to operate, check batteries and test leads etc., and
replace as necessary. Double check operating procedure as described in this
user’s manual
If the instrument voltage-resistance input terminal has 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 off (become high impedance) 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.
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
22
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.
