Applications
METRAport 40S digital multimeters are very well suited for universal
use in general electrical engineering, electronics applications and for
automotive service. Ideal reading angle adjustment is made possible
by the tilt stand, and when suspended from the neck strap both
hands are free for performing measurements. The instrument is
switched off automatically when folded closed, and the display and
the control panel are protected against damage.
Features
RMS Value with Distorted Waveshape
The utilized measuring method allows for waveshape independent
TRMS AC measurement for voltage and current at up to 10 kHz.
Automatic / Manual Measuring Range Selection
Measured quantities are selected with the rotary switch. The meas-
uring range is automatically matched to the measured values. The
measuring range can be selected manually as well with the help of
the AUTO/MAN key. Direct current measurement in all ranges via a
single socket: measurement cable does not have to be replugged.
Clip-on current measurement is performed via a separate socket.
Automatic Storage of Measured Values
The DATA function allows for storage of the digitally displayed
measured value. A special process assures that random values
are not saved to memory in the case of rapidly changing
measured quantities, but rather the actual measured value. The
stored measured value appears at the digital display. The analog
display continues to read out the current measured value.
Storage of Min-Max Values
In addition to displaying the current measured value, the minimum
or maximum value can be continuously refreshed and saved to
memory.
Continuity and Diode Testing, I
k
= 1 mA
This function can be used to test the polarity of diodes, and to
test electrical circuits for short-circuits and interruptions. The test
voltage source makes it possible to measure LEDs and reference
diodes with up to 5.1 V. In addition to the display, an acoustic
signal is generated during continuity testing of resistors within a
range of 0 to 2 .
Duty Cycle Measurement – Measurement of 5 V Square-Wave Signals
This function makes it possible to test circuits and transmission
cables by measuring the frequency and the duty cycle of pulses
with amplitudes of 2 to 5 V and frequencies of 100 Hz to 10 kHz.
Battery Charging Status – Power Saving Circuit
The battery charging status is indicated by means of a symbol
with four different levels. The device is switched off automatically if
the measured value remains unchanged for a period of 10
minutes, and if none of the controls are activated during this time.
Automatic shutdown can be deactivated by switching the
instrument to continuous operation.
Auto-Fuse and Fuse Detection for all Current Ranges
User-friendly thanks to resetable auto-fuses. Fuse detection: The
FUSE message is displayed in order to indicate that the auto-fuse
has blown. The fuse interrupts the current measuring ranges only.
All other ranges remain functional.
