Employs high-performance fuses rated at 100 kA
Uses withstand current fuses with an arc extinguishing material
for an assured prearcing time-current characteristic in the
event of an excessive current.
Terminal shutters prevent erroneous insertion
of test leads into current measurement terminals
If the function is switched to voltage measurement while a
test lead is left inserted into a current measurement terminal,
neither the fuse built into the current measurement circuit of
the DMM nor the input protection circuit for voltage measurement
can protect the circuits. The terminal shutters prevent the
rotary switch from being moved from the current measurement
function while a test lead is inserted into a current
measurement terminal, thus preventing erroneous settings due to
human error and ensuring the safety of the user. The terminal
shutters open and close with operation of the function select
(rotary) switch, so operation efficiency is not sacrificed.
AC voltage measurement method selectable between RMS value
and mean value measurement (73303 Only)
You can compare the waveform of the measured AC voltage with a
sine wave to check for distortion. If the measured RMS value is
not equal to the measured mean value, you can conclude that the
waveform deviates from the sine wave.
Duty ratio (%) measurement
Displays the duty ratio of a pulse waveform: High level period/1
cycle of waveform) x 100 = (t2/t1) x 100 [%]
Zero calibration for stray capacitance when checking capacitors (73302/03)
The stray capacitance of the instrument can be zeroed by using
this function with the test leads open (only when the 10 nF
range is selected).
Auto hold
Just removing the test leads from the measured object retains
the measured value. Because the measurement is held, there is no
need to operate the hold switch for each measurement, freeing
both hands for performing safe and accurate measurements with
the test leads
