• Configure the METRAHIT⏐X-TRA⏐OUTDOOR from a PC.
• Transmit live measurement data to the PC.
• Read out data from memory at the METRAHIT⏐X-TRA⏐OUTDOOR.
The adapter does not require a separate power supply.
Its baud rate is 38,400 baud.
A CD ROM is included which contains current drivers for
Windows operating systems.
Multimeter-display Tabular display
for up to 4 channels for up to 10 channels

System Requirements
METRAwin 10 (as from version 5.3) can be run on IBM compatible
PCs with Microsoft Windows® 98, ME, NT 4.0, 2000, XP, VISTA (32/
METRAwin10/METRAHit  Software
64 Bit) or 7 (32 Bit).

METRAwin10/METRAHit  PC software is a multilingual, measure-

ment data logging program for recording, visualizing and documen-
ting measured values from METRAHIT⏐X-TRA⏐OUTDOOR multimeters.
Communication between the PC and the measuring instrument(s)
is established via available interfaces and memory adapters. Tele-
phone modems can be interconnected as well.
Depending upon device type, one or several of the following ope-
rating modes are possible:
• Device Configuration
Remote configuration and querying of device-specific functions
and parameters, for example measuring function, measuring
range and memory parameters. Frequently used device settings
can be saved to configuration files for easy recall.
• Online Recording of Measurement Data
Read-in, display and recording of momentarily measured data
from the interconnected device.
– Number of
measuring channels up to10
– Start recording manual, triggered by measured value, time
triggered
– Recording mode > time controlled
with sampling interval of 0.05 s* ... 1 s ...
60 min
> manually controlled
> measured value controlled in event
of exceeded limit/delta value
– Recording duration max. 10 million intervals
* Depending upon device type, measuring function, number of measuring channels
and communication (e.g. via modem), sample intervals of less than 1 s cannot be
used.

• Reading Out and Visualizing Stored Data

If supported by the device: read-in and display of offline data
recorded to device memory.
