1 Applications
The adapter makes it possible to connect a multimeter with IR
interface to the USB port at a PC. The adapter allows for data
transmission between the multimeter and the PC.
USB X-TRA: For Starline multimeters
– METRAHIT A, E and S series
USB HIT: For METRAHIT 22 ... 29S/M/C/I, 30M and World
multimeters and calibrators
2 Installing the Device Drivers
A CD ROM with drivers for Windows XP, Vista (32/64 bit),
Windows 7 and 8 is included with the adapter.
The drivers have to be installed before connecting the USB
adapter to the PC. Insert the included CD into the CD ROM drive
at your PC to this end. Install Driver Control software by selecting
„GMC-I Driver Control Setup…“ and executing the installation
sequence. Then start Driver Control software in order to install the
device drivers. Acknowledge all certificates despite the missing
digital signature. Please note that administrator rights may be
required in order to install drivers.
Please visit our website at http://www.gossenmetrawatt.com, from
which current software and any available updates can be down-
loaded. The USB2COM driver installation program can be found
here as well, which is required for Windows 98SE and 2000.
Note regarding USB X-TRA:
The installed driver assigns virtual COM ports to the adapters
connected with the multimeters. Upon starting the communica-
tion test in the METRAwin10 software, it finds all multimeters
which are connected to the USB ports and displays their currently
adjusted measured quantity. Currently, a multi-channel system
can be set up with up to 4 multimeters.
Note regarding USB HIT:
Due to the fact that addressing takes place via the COM port,
only one adapter can be read out at a time via METRAwin10.
Open the device manager (Start > Settings > Control Panel >
System > Hardware > Device Manager > Connections (COM and
LPT) > Z216A IR-USB Port (COMx)) in order to determine which
COMx address (x = 1 ... 8) has been assigned to this end, and
enter it to METRAwin10 (Device > Communication > COMx).
If several METRAHIT 22 ... 29S/M/C/I, 30M and World multime-
ters need to be connected online with the PC at the same time,
this is only possible with the help of the BD232 or SI232 adapter,
which is connected to the PC via an RS 232-USB converter.
3 Connection
The adapter is plugged into any available USB port at the PC.
Separate supply power is not required, because the adapter is
supplied with electrical power via the USB port.
USB X-TRA: Insert the studs on the adapter into the openings at the
front of the multimeter so that the cable points to the left as seen
from the front, and the socket for the power pack is not
obstructed. Communication via the interface is only possible with
the adapter in this position.
USB HIT: Push the upper part of the multimeter onto the adapter as
far as it will go. The guides for the multimeter’s rubber feet secure
both devices securely in this position
