METRAHITISO
TRMS Multimeter with Insulation Measurement
2 GMC-I Messtechnik GmbH
Automatic Storage of Measured Values
The DATA HOLD function automates the storage of measured
values after they have settled in. A patented 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.
Overload Protection
Overload protection safeguards the instrument in all measuring
functions against voltage of up to 1000 V. Voltages of greater than
1000 V and currents of greater than 10 A are indicated
acoustically. FUSE appears at the display if the fuse for the
current measuring input blows.

Issue
Multimeters manufactured as of 1 January 2004 may not be the
source of any possible hazard, regardless of the utilized
combination of input voltages, function settings and range
selections. Possible hazards include electrical shock, fire,
sparking and explosion.
Battery Charging Status – Power Saving Circuit
The battery charging status is indicated by means of four symbols.
The device is switched off automatically if the measured value
remains unchanged for a period of between 10 and 59 minutes
(adjustable), and if none of the controls are activated during this
time. Automatic shutdown can be deactivated by switching the
instrument to continuous operation.
Three Connector Jacks with Automatic Blocking Sockets (ABS) *
All current ranges are implemented via a single connector jack
which prevents any possibility of operator error. Beyond this, the
automatic blocking sockets prevent incorrect connection of the
measurement cables, as well as selection of the wrong measured
quantity. Danger to the user, the instrument and the device under
test resulting from operator error is thus ruled out.
* Patented (patent no. DE 40 27 801 C2 and US 5,166,599)
Housing and Protective Cover for Harsh Conditions
• New housing design
• Separate battery and fuse compartments
• Intelligent key functions with SMD button
The instrument is protected against damage in the event of
impacts or dropping by means of a soft rubber cover with tilt
stand and test probe holder. The rubber material also assures
that the instrument does not wander if it is set up on a vibrating
surface.
Infrared Data Interface
The device can be remote configured, and momentary and saved
measurement data can be read out via the bidirectional infrared
interface. The USBX-
TRA interface adapter and METRAwin 10
software are required to this end (see accessories). Interface
protocol and device driver software for LabVIEW
®
(National
Instruments™) are available upon request.
Voluntary Manufacturer’s Guarantee
36 months for materials and workmanship
1 to 3 years for calibration (depending upon application)
DKD calibration certificate
METRAHITI
SO cable multimeters are furnished with an
internationally valid DKD calibration certificate (recognized by EA
and ILAC).
In addition to standard quantities, our DKD calibration lab is also
accredited for high value ohmic resistance of up to 30 G /
1000 V.
A
fter the specified calibration interval has elapsed (recommended
interval: 1 to 3 years), the multimeters can be inexpensively
recalibrated at our own DKD calibration center.
