RMS Value with Distorted Waveshape
The utilized measuring method allows a waveshape
independent RMS measurement (TRMS AC and AC+DC) for voltage and
current (METRAHIT EXTRA up to 20 kHz).
Selectable Filter for V AC Measurement
A 1 kHz low-pass filter can be selected if required,
for example to measure the motor voltage at electronic frequency
converters. The input signal is checked by a voltage comparator for
dangerous voltages as long as the low-pass filter is activated. A
high-voltage symbol appears at the display if
dangerous voltage is present.
Analog Scale for Quick Trend Display – Bar Graph
or Pointer
The analog scale (with additional negative range for
zero frequency quantities) allows for faster recognition of measured
value fluctuation than is possible with a digital display.
The instrument can be switched back and forth between bar graph and
pointer display via the menu.
Automatic or Manual Measuring Range Selection
Measurement functions are selected by a rotary dial
and a function key. The measurement range selection is done
automatically according to the input signal. Manual measurement
range selection
is possible via function key.
Measurement with current clamps and sensors
Current clamps and sensors are used for current
measurements without interrupting the circuit under test and for
high currents above 16 Amps. All E series multimeters offer
convenient measurement
with current clamps.
The measured current value is automatically calculated for the user
with the help of the adjustable clamp factor.
Fast Acoustic Continuity Test
Testing for short circuit connection and circuit
interruption is possible with the selector switch in the position.
The threshold value for acoustic response can be set to 1, 10, 20
... 500 Ω in 10 Ohm steps.
Automatic Storage of Measured Values *
The DATA function automatically saves the digitally
displayed measured value after stabilization in. Acoustic signaling
is also used to indicate whether the new measured value deviates
from the initial reference value by less or more than 0.1% of the
measuring range.
