Introduction
Note
The LED OK is red if no valid sensor can be detected.
The limits for ‘Signal too low’ and ‘Signal too high’ are equal to the
thresholds for voltage dips and voltage swells (e.g.
For current inputs ‘Signal too low’ is indicated for half cycle or full cycle
rms values below 10 % of the sensor range as configured in the “Hardware
Settings” panel (if sensor is set to “Auto” the “Signal too low” indication
is deactivated).
‘Over range’ is indicated if the input signal is outside the valid
measurement range.
The phase voltages UL1, UL2, and UL3 of a three-phase system are monitored with the
symmetrical components (zero, positive and negative system). If the negative system
exceeds an upper threshold a wrong phase sequence condition is indicated (e.g. two lines
interchanged); the associated LEDs are flashing in sequence L3-L2-L1.

is supported.
USB connectors have the following function:
• USB stick support for storing of measurement data (same as external CF card).
CF card LED behaviour during USB copy process:
• copy process started --> flashing LED
• copy process finished and all data copied --> LED goes off
• copy process finished but not all data could be copied --> LED is turned on statically
• on error --> fast flashing LED for approx. 3 seconds then statically on
USB stick must not be pulled out while CF card LED is flashing. This can
cause permanent damage to the storage media. Only remove CF card /
USB stick while CF card LED is OFF or statically ON. Do not use CF card
or data connection at the same time.

H Measurement Channels
Plugs for 8 isolated measurement channels. Connect only original accessories such as
voltage and current sensors (clamps, Flexi Set, shunt resistors, etc.). The plug is secured
by means of a bayonet mechanism.
Note
Inputs that are not in use must be covered with the supplied protective caps
to prevent pollution.
When analyzing transients with 500 kHz transient option or 10 MHz
transient option, the potential to earth/ground is measured.

I J Compact Flash Card
Replaceable Compact Flash card for storage of measurement data. J Compact Flash
eject button and LED. Do not operate when data transfer is active (LED indicates
activity).
CF card LED behaviour during CF copy process:
• CF card inserted and detected --> short flashing (double pulses)
• copy process started --> flashing LED
• copy process finished and all data copied --> LED goes off
• copy process finished but not all data could be copied --> LED is turned on
statically
• on error --> fast flashing LED for approx. 3 seconds then statically on
Notes
• CF card must not be pulled out while CF card LED is flashing.
This can cause permanent damage to the storage media. Only
remove CF card / USB stick while CF card LED is OFF or
statically ON. Do not use USB stick or data connection at the same
time.
• Stored data can be erased by holding down the Reset Button K
while switching on (booting) the instrument. This may be useful
when the memory is full and may also resolve connectivity issues.
Basic Measurements
The Instrument offers all functions necessary to perform network analysis, quality
assurance evaluations and location of disturbance sources. A large compact flash data
memory provides a method of effecting long-term recordings. All data is saved even
without connection of the instrument to an evaluation computer. No information will be
lost. The recordings are the basis for detailed evaluations and analyze to assess
disturbances and the mains voltage quality. The instrument records and provides
historical event data, which protective relays or protective switches have induced and
how the resources have performed.
Measurement Types
The instrument combines many different measurement types, also referred to as “virtual
instruments”:
• Digital recording of measured data (data logger)
• Power measuring device (recording of load profiles)
• Recording of power frequency
• Power Quality Analyzer (including statistical evaluation)

• Fast transient recorder (optional)
• Ripple control signal analyzer
• Harmonics analyzer
• Voltage disturbances analyzer (events)
