This Meter measures the true-rms
v
alue of Alternating
Current (AC) over from 0.3A to 700A. AC mea
s
urements
are from 10Hz to 1KHz and frequency measurements are
from 0.5Hz to 10KHz.
Clamp meters that measure average current flow are
inaccurate for non-linear currents and their measurements
may have some differences from those obtained using this
Meter.
This Meter can also measure frequency while measuring
current flow simultaneously. AC and DC voltages and
resistances can be measured and also continuity check is
possible with this Meter.
This Meter also provides:
■Auto Range or Manual Range
s
election.
■HOLD function to freeze readings.
■41-segment analog bar graph that disp
l
ays current while
simultaneou
s
l
y measuring frequency on the digital display.
■
Low- battery indicator and battery l
i
fe indicator at
powerup using bar graph.
■Automatic power off after 10 minutes of inactivity and
power lock to disable the automatic power off function.
■When an
i
neffective pushbutton is pressed, this Meter
beeps twice continuously.
■
A SOFT mode to display a 3-second running average.
■A CREST mode that measures half-c
y
cle peak AC
amperes.
■A MIN/MAX RECO
R
D mode to record maximum,
minimum, and average values of rms current, softened
rms, frequency, vo
l
tage or ohms. Half-c
y
cle peak
maximum may also be recorded in the CREST mode.
■Zero adjustment by the microprocessor when measuring
DC amperes.

z
ard that can cause
death or injury; the word “WARNING” identifies a personal
hazard about a condition or procedure that could cause
death or injury; the word “CAUTION” identifies an

could cause damage or destruction of this Meter.
Observe the International Electrical Symbols listed below.
Warning! Risk of electric shock.
Caution! Refer to this manual before using this Meter.
Double Insulation (Protection Class ll)
■Never clamp around a conductor at 600V rms or greater
or with a frequency of 10KHz or greater.
■Never use a meter whose insulating protection has been
impaired.
■
Be extreme
l
y
cautious when clamping around
uninsulated conductors or bus bars.
■U
s
e this Meter only as specified in this manual. Otherw
i
s
e,
the protection provided by this Meter may be impaired.
■Observe the safety messages contained in this manual.
■Avoid working alone.
■Inspect the test leads for damaged insulation or exposed
metal. Check test lead continuity. Damaged leads should
be replaced.
■Disconnect the live test lead before dis-connecting the
common test lead.
■Be sure this Meter is in good operating condition. During a
continuity test, a meter reading that goes from overflow
(OFL) to 0 generally means this Meter is working properly.
