Measuring Functions
Measuring Functions
Overview
The following information provides an overview of each rotary switch position.
Meter Volts / Amps / Hz
This function displays the voltage and current values at the same time, plus the
frequency and the neutral-conductor current. You can also use this measuring
function to get an overview of these values before you analyze the signal in
detail in the other functions.
Scope
Scope shows the voltages, currents and the ϕ (phase) angle in oscilloscope
representation as well as their instantaneous values at the cursor position. With
this function you get a clear picture of current and voltage waveforms and their
distortions.
Harmonics
Harmonics are sinusoidal voltages with a frequency that corresponds to an
integer multiple of the fundamental (line) frequency.
Every repetitive signal can be split into an infinite number of sine waves of
different frequency and amplitude. The contribution of each of these individual
sine waves is represented in a bar chart up to the 40

Note
Demand can be logged by setting the averaging period in the Setup
menu to either 10 or 15 minutes, which produces a record of
consecutive averages. This is called block demand.

Events are voltage dips, swells and interruptions. This measuring mode
automatically records all events for later evaluation. The threshold values for
starting the recording are freely configurable in the menu.
Connecting the Power Logger to the Network
XWWarning
• To prevent the risk of electric shock, when
connecting current circuits, the corresponding test
leads must first be connected to the Logger and
then to the load.
• Adhere to local and national safety codes.
Individual protective equipment must be used to
prevent shock injury where hazardous live
conductors are exposed.
• Use only specified current probes. If flexible
current probes are used, wear suitable protective
gloves or work on de-energized conductors.
• To avoid shock or personal injury, keep fingers
behind the tactile barrier, see Figure 5.
Note
When using either flexi-probes or current clamp sets, make sure the
arrow on the current probe points towards the load.
Use the original cables only for connecting the current probes and the voltages
to the Logger. If these are damaged do not use them. Before connecting to the
load, make sure that all plugs are connected correctly to the Logger and locked,
in order to prevent contact with live conductors.

i2 (t) =-[i1(t)+ i3(t)]
In general, the instantaneous total power is:
• Ptot(t)=v1(t) i1(t)+ v2(t) i2(t)+ v3(t) i3(t)
• Ptot(t)= v1(t) i1(t)- v2 [i1(t)+ i3(t)]+ v3(t)i3(t)=
=[v1(t)- v2(t)] i1(t)+[ v3(t)-v2(t)]i3(t)
However, since the voltages between the lines of a poly-phase are measured in
the delta connection, the following formula results for the total power:
Ptot(t)= v12(t) i1(t)+v32 i3(t)
Integration via a period results in:
Ptot= V12 I1 cos (V12, I1) +V32 I3 cos (V32, I3)
Therefore, the total power corresponds to the total power of the Wye
connection. For control purposes, it can be derived from the sum of the powers
P
and P31.
12
Since I
is only calculated as an auxiliary value and is not measured, P23 must
L2
be set to zero (as per definition), because it does not exist in the Aron circuit.
The power factor PF has no physical meaning in the Aron circuit, because one
would compare the current to the voltage between the lines of a poly-phase
system. Reactive and apparent power should be understood as pure computing
values and have no physical meaning.
Invalid measurements are suppressed from the display by the symbol ‘----‘.
The exact formulae for calculating the active power are given in the section

Line Power or Battery Mode
You can operate the Logger continuously with the provided charging adapter
or for a few hours with the built-in battery. The battery is to ride through
power interruptions during logging sessions, and to provide operating power
during handheld troubleshooting and analysis of signals.
If you operate your Logger with the ac adapter, the battery is charged
automatically. On the display the symbol for “plugged-in” or battery is
displayed accordingly.
If the battery is completely discharged, it takes about 4 hours to charge it
completely. It is impossible to overcharge the battery as the Logger has an
automatic charging circuit.
When LO-BAT is indicated, attach the ac adapter to recharge the battery.
Replacing the Battery Pack
If the battery life is noticeably low (see technical specification), then it has to
be replaced. Replace the battery as follows, refer to Figure 13:
1. Turn off the Logger
2. Disconnect all measuring leads
3. Open the battery compartment (two cross-notched screws)
4. Unplug and replace the battery pack. Close the battery compartment
again.
