Analog Bargraph
The analog bargraph provides a visual indication of measurement
like a traditional analog meter needle.
AC coupling True RMS
When measurement is taken by true r.m.s., the measurement
value of input signal becomes the scales of the signal power
and therefore provide more effective values than those
obtained by average value detection. This multimeter imploys
this true RMS circuit, which enables measurement of sine wave
and non-sinusoidal waves like square wave and triangular
wave in r.m.s.
AC+DC coupling True RMS
DC+AC True RMS calculates both of the AC and DC components
given by the expression
DC
2
+(AC rms)
2
when making
measurement, and can respond accuratel y to the total
effective RMS value regardless of the waveform.
Crest Factor
The crest factor (CF) is expressed by a value obtained by
dividing the peak value of the signal by its RMS value. Most
common waveforms such as sine wave and triangular wave
have a relatively cycle have a high crest factor. The voltages
and crest factors of typical waveforms are shown in the table.

Please note the measurement should be taken at the crest

NMRR (Normal Mode Rejection Ratio)
NMRR is the DMM's ability to reject unwanted AC noise effect,
which causes inaccurate DC measurements. NMRR is typically
specified in terms of dB (decibel). This series has a NMRR
specification of >60dB at 50 and 60Hz, which means a good
ability to reject the effect of AC noise in DC measurements.
CMRR (Common Mode Rejection Ratio)
Common mode voltage is voltage present on both the COM
and VOLTAGE input terminals of a DMM, with respect to
ground. CMRR is the DMM's ability to reject common mode
voltage effect, which causes digit rattle or offset in voltage
measurements. The CMRR function of this meter is activated at
>90 dB at DC to 60 Hz with the ACV measuring function, and at
>120 dB at DC or 50/60 Hz with the DCV measuring function.

a year to maintain the safety and accuracy.
WARNING

31

6-1 Maintenance and Inspection

1) Appearance
Is the appearance not damaged by falling, etc?
2) Test leads
Is the cord of the test leads not damaged?
Is the core wire not exposed at any place of the test leads?
NOTE:
If the built-in fuse is blown, only the current measurement
does not work.
Make sure that the test leads are not cut, referring to the
section 5-1.
6-2 Calibration
The manufacturer may conduct the calibration and inspection. For
more information, please contact the manufacturer.
6-3 Battery and Fuse Replacement
1. If the rear case or the battery lid is removed when any input is
applied to the input terminals, you may get electrical shock. Before
starting the work, always make sure that no input is applied.
2. Before starting the work, be sure to turn OFF the main power
and release the test leads from the circuit.
3. Be sure to use a fuse of the specified rating or type. Never use
a substitute of the fuse or never make a short circuit of the fuse.
WARNING
Factory-preinstalled built-in battery
A battery for monitoring is preinstalled before shipping,
therefore it may run down sooner than the battery life specified
in the instruction manual.
The "battery for monitoring" is a battery to inspect the functions
and specifications of the product.
