EHP-50D Operation
The EHP-50D adopts the same extremely flexible operating
concept found in preceding models, such as “Stand Alone” mode,
remote control by PC via an optical connection, and remote E
and H field sensor for portable field meter.
The EHP-50D as well as its different operating modes therefore
appears to be the same as the EHP-50C but it has a completely
new “heart” beating within it to give the highest level of
performance even in the most complex situations.
The EHP-50D was designed to provide all the performance,
capacity and functions needed, and is shown as the best tool for
measuring low frequency electric and magnetic fields and
displaying, recording and analyzing their values on the NBM-550
field meter or a PC screen. The PC program allows for remote
control by optical fiber as well as for setting the probe and
downloading measurement results acquired in "Stand Alone"
mode or stored in the NBM-550 memory. The EHP-50D provides
an advanced solution for field measurements in the 5 Hz to 100
kHz range, with an unsurpassed total dynamic range of up to 150
dB and a built-in spectrum analyzer function.
EHP-50D Operating Modes
- Stand-Alone Operating Mode
- NBM-550 Display Operation
- EHP-TS Remote Controlled Operation
STAND-ALONE OPERATING MODE
Continuous acquisition with internal data logger for
up to 24 hours
When long-term monitoring is essential, such as when measuring
magnetic fields close to high, medium and low voltage
transformers, close to power lines or to machinery, air
conditioning systems, large home appliances, and so on, the
EHP-50D can be used in stand-alone mode
without needing to be connected to a PC or a NBM-550 meter.
Once the measurement parameters have been programmed
using the PC software (supplied), the EHP-50D analyzer can
start acquisition and storage of the data in stand-alone mode for
a period of 24 hours at a sampling rate of once every 30 or 60
seconds. The EHP-50D will stop automatically after 24 hours.
EHP-TS control software includes the
application "EHP50 - Stand Alone mode"
The data can then be downloaded to the PC. The PC software
enables you to select measurement (electric or magnetic field),
full scale, mode (Highest or Wideband), frequency span, and
sampling interval (one minute or 30 seconds).
