3.3 Functions
The power analyzer allows for the analysis of currents from DC to
several MHz. Voltage values up to 1000 V and currents up to 20 A
are measured accurately, and the respective real, idle and
apparent power is calculated. The limit of error is between 0.1%
and 0.3%, depending on the model. For DC and AC up to a few
MHz, it is not affected by the wave shape, frequency or phase
position. The measuring range can be extended by connecting
shunts or clamps. When extending the range using third-party
shunts or clamp the extra errors due to these devices should be
considered. The device caters for simultaneous measuring in up to
6 channels.

Fehler!AutoText-Eintragnichtdefiniert.
Danger! Risk of electrocution
 Caution! The device is connected to the power mains, and a
number of internal components are live with dangerous voltage
levels. To remain safe during operation, the device must be
equipped with a low-resistance connection to the earth.
 Therefore check the mains socket and its wiring!
 Place the device onto a clean and stable surface.
 If necessary adjust the feet at the base of the unit to improve
the view onto the display.
 Connect the device to the mains socket, using the power lead.
 Set the power switch at the rear of the housing to position "I".
The device is now ready for operation. The start screen is
displayed.
 Set the power switch at the rear of the housing to position "0".
 If the device is not to be used for a prolonged period of time,
disconnect the plug from the mains socket.

Fehler!AutoText-Eintragnichtdefiniert.
Danger! Risk of electrocution!
 By connecting the unit to circuits, the terminals and certain
parts inside the device are live.
 In order to ensure safe operation, first connect the device to the
power supply.
 If possible, open the circuit before establishing a connection to
the analyzer.
 Prior to connecting the circuits, ensure that the maximum
measuring voltage and max. voltage to earth (1000V CATII and
600V CATIII respectively) are not exceeded.
 Do not use leads and accessories that do not fulfil the relevant
safety standards, as this could lead to serious injury or death
from electric shock!
5.1 Connecting sequence
When connecting a circuit to the power analyzer, for safety
reasons, proceed in the sequence outlined below:
1. Connect the power analyzer to the mains socket.
The analyzer is now connected to the protective earth wire.
2. Switch on the power analyzer.
3. Connect the measuring circuit as shown in the connection
diagram.
Ensure that the phase is connected to HI so that the energy
flow is from HI to LO; to ensure that the measured values are
indicated correctly.
4. Connect the circuit to the power supply.
5.2 Overview
The power analyzer offers the following options for connection:

Note
When connecting a 4-channel device for electrical efficiency
analysis, the 3-phase power cables for this measurement should be
connected to the measuring channels 1 to 3, so that the efficiency
can be calculated and displayed directly on the device.

5.4 Aron circuit (triaxial/guard technique)
5.4.1 Direct connection
the Aron circuit is only available for 3-wire networks.
It is only required to measure two phases (currents I1 and I2 in the
connection diagram), as I1+I2+I3 must be 0.
Important
In most cases, the Aron circuit is not acceptable for measurements
on inverters, as there are capacitive leakage currents from the
windings to the housing!
 Ensure that there is no overload at the current input of the
power analyzer.
 If necessary, install appropriate fuses.

voltage as the power connections.
Shunts are not isolated.
 Never touch the sense terminals at the shunts.
 The connecting leads to the shunts should be as short as
possible in order to prevent noise voltages.
Fehler!AutoText-Eintragnichtdefiniert.
Danger! Risk of electrocution!
Risk of injury when touching connections, internal circuits and
measuring devices that are not earthed.
 Always adhere to the instructions regarding the sequence of
connection (see page 12).

Risk of damage to transducer due to overload!
 Check rating of transducer.
Note
When using transducers, please note that transducer errors limit
the measuring bandwidth and reduce the intrinsic uncertainty.
