The METRAHit
30M multimeter is a
high performance, precision measuring instrument for R&D labs,
industrial applications, universities, government authorities, testing
stations, manufacturing and QA.
With a display range of 1,200,000, as
well as exceptional accuracy and long-term stability,
it fulfills all
of the demands of calibration and R&D labs.
Battery operation allows for mobile use of the instrument for
demanding maintenance work and calibration tasks.
An optional mains power pack can be utilized for stationary, long-term
operation.

TRMS Measurement for
Distorted Waveshapes
The utilized measuring method allows for TRMS measurements for up
to 100 kHz at crest factors of up to 10, independent of the waveshape.
Sampling Rate
The sampling rate determines the interval at which the respective
measurement value is saved to memory.
Depending upon measured quantity
and resolution, the interval can be set
within a range of 0.01 s to 60
s.
Automatic and Manual Measuring Range Selection
The desired measured quantity is selected with the rotary switch.
The measuring range is automatically adapted to the measured quantity.
The measuring range can also be selected
manually.
Averaging Filter
A digital filter (1/2/4/8/16 measurement values) is used to smooth
noisy measurement signals.
Storing MIN-MAX Values to Memory
In addition to displaying the current measurement value, the
minimum or maximum
value can be continuously updated and stored to
memory at the selected sampling rate.
Continuity Testing
Continuity testing allows for the detection of short-circuits and
interruptions.
An acoustic signal can be generated in addition to a
visual display.
Overload Protection
The instrument is protected against overloading in all measuring
functions.
All current measuring ranges are equipped with a self
resetting, electronic fuse.
Battery Saver Circuit
The instrument is shut down automatically if the measurement value
remains unchanged for approximately 10 minutes, and if none of the
operating elements have been activated during this time. Automatic
shut-down can be disabled.
Protective Cover for Rugged Use
A soft rubber cover with tilting stand protects the instrument
from damage due to impacts or drops.
The rubber material provides the instrument with a secure stance, even
if it has been set up on a vibrating surface.
Memory Mode
The METRAHit
30M multimeter is equipped with a 128 kB measurement value memory
with backup battery.
The memory can be laid out in 1 to 15 blocks. New values can be
written to memory, even after completion of a given measurement
without loss of data, until the maximum capacity of 30,000 measurement
value has been used up. The data can be stored to intermediate memory,
or uploaded directly to a PC. The system records measurement values in
relative time.
Use as a real-time data logger is not possible. Depending upon the
measured quantity,
the interval can be set in steps of 10 ms, 100 ms,
1 s, 10 s and 60 s.
Individual measurement values can also be saved to
memory by pressing a key. The contents of the memory can be read out
with the help of METRAwin10/METRAHit analysis software and a PC which
has been connected to the multimeter via the METRAHitBD232 IR adapter.
Infrared Measurement Data Transmission
The measuring instrument includes a serial, duplex data interface for
remote control and transmission of data via infrared light.
