The waveforms on today’s AC power lines are anything but clean. Electronic equipment such as office computers, with their switching
power supplies, produce harmonics that distort power-line waveforms. These distortions make measuring AC voltage inaccurate
when you use an averaging DMM.
USE TRUE RMS WHEN MEASURING
AC WAVEFORMS
®
Average voltage measurements work fine when the signal you’re measuring is a pure sine wave, but errors mount as the waveform
distorts. By using true RMS measurements, however, you can measure the equivalent heating effect that a voltage produces,
including the heating effects of harmonics. Table 1 shows the difference between measurements taken on averaging DMMs & those
taken on true RMS DMMs. In each case, the measured signal’s peak-to-peak value is 2V. Therefore, the peak value is 1V.
For a 1-V peak sine wave, the average & RMS values are both 0.707V. But when the input signal is no longer a sine wave, differences
between the RMS values & the average readig values occur. Those errors are most prominent when you are measuring square waves
& pulse waveforms, which are rich in harmonics.
Table 1. Average versus true RMS comparison of typical waveforms.

2.000 0.331 0.243 -26.5%
2.000 0.242 0.130 -46.2%
One limitation to making true RMS measurements is crest factor, and you should consider crest factor when making AC measurements.
Crest factor is the ratio of a waveform’s peak (”crest”) voltage to its RMS voltage. Table 2 shows the crest factors for ideal waveforms.

A DMM’s specifications should tell you the maximum crest factor that the meter can handle while maintaining its measurement
accuracy. True RMS meters can handle higher crest factors when a waveform’s RMS voltage is in the middle of the meter’s range
setting. Typically, a DMM may tolerate a crest factor of 3 near the top of its scale but it might handle a crest factor of 5 that’s in the
middle of the range. Therefore, if you’re measuring waveforms with high crest factors (greater than 3), you should adjust the DMM
so the measured voltage is closest to the center of the measurement range.
Another limitation of true RMS is speed. If you’re measuring relatively clean sine waves, then you can save time & money by using as
averaging DMM. True RMS meters cost more than averaging meters and can take longer to produce measurements, especially when
measuring millivolt-level AC signals. At those low levels, true RMS meters can take several seconds to stabilize a reading. Averaging
meters won’t leave you waiting.

I. SAFETY :
This manual contains information and warnings that must be
followed for operating the instrument safely and maintaining the
instrument in a safe operating condition. If the instrument is used in
manner not specified by the manufacturer, the protection provided
by the instrument may be impaired.
The meter protection rating, against the users, is double insulation
per UL/IEC/EN61010-1 Ed. 3, IEC/EN61010-2-033 Ed. 1, CAN/

Per IEC610-1 (2010) OVERVOLTAGE CATEGORY
OVERVOLTAGE CATEGORY II (CAT II) is for equipment intended
to be supplied from the building wiring. It applies both to plug-
connected equipment and to PERMANENTLY CONNECTED
EQUIPMENT.
OVERVOLTAGE CATEGORY III (CAT III) is for equipment intended
to form part of a building wiring installation. Such equipment
includes socket outlets, fuse panels, and some MAINS installation
control equipment.
OVERVOLTAGE CATEGORY IV (CAT IV) is for equipment installed
at or near the origin of the electrical supply to a building, between
the building entrance and the main distribution board. Such
equipment may include electricity tariff meters and primary over
current protection devices.

WARNING :
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. Only
use the test lead provided with the equipment or UL Listed Probe
Assembly rated CAT III 600V or better.
This Clamp-on meter is designed to apply around or remove from
uninsulated hazardous live conductors. But still, individual protective
equipment must be used if hazardous live parts in the installation
where measurement is to be carried out could be accessible.
CAUTION :
Disconnect the test leads from the test points before changing meter
functions.

Electric Field EF-Detection
The meter displays “EF” when it is ready. Signal strength is indicated
as a series of bar-graph segments on the display together with
variable beep tones.
vNon-Contact EF-Detection : An antenna is located along the
top-right end of the stationary clamp jaw, which detects electric
field that surround energized conductors. It is ideal for tracing
live wiring connections, locating wiring breakage and to
distinguish between live or earth connections.

CAUTION & WARNING for Non-Invasive (Clamp-on) Current
Measurements :
CAUTION :
(Application and Removal of the Clamp-on Jaws) For non-invasive
current measurements, press the jaw trigger and clamp the jaws
around conductor(s) of only one single pole of a circuit for load
current measurement. Make sure the jaws are completely closed, or
else it will introduce measurement errors. Enclosing conductor(s) of
more than one pole of a circuit may result in differential current (like
identifying leakage current) measurement. Align the conductor(s) to
TM
the Jaws center indicators (Regular or AmpTip indicators where
applicable) 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 may affect measurement accuracy. Keep the jaws
away from them as much as possible to minimize influence.
WARNING :
Do not use the meter to measure currents above the rated frequency
(400Hz). Circulating currents may cause the magnetic circuits of the
Jaws reach a hazardous temperature.

Note : When using diode test function, normal forward voltage drop
(forward biased) 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). An OL indicates
an open diode (defective). Reverse the test leads connections
(reverse biased) across the diode. The digital display shows OL if the
diode is good. Any other readings indicate the diode is resistive or
shorted (defective).
CAUTION :
