software is a multilingual, measure-
ment data logging program for r
ecording, visualizing and docu-
menting measured values from METRA HIT AM XTRA / 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 oper-
ating modes are possible:
• Device Configur
ation
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 mome
ntarily 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
r
ecorded to device memory.
For purposes of analysis, data recor
ded online or read in from the
device’s memory can be displayed in various formats:
Y(t)-recorder display
for up to 6 channels
XY-recorder display
for up to 4 channels
Multimeter-display
for up to 4 channels
Tabular display
for up to 10 channels
