5.2. First use

At delivery, the built in chargeable battery may be empty and it is recommend to
charge it before use. A full charge for the first time takes at least 6 hours, it means
the battery is fully charged when the charging indicator change from red to off. No
damage will occur if the adapter is connected with the Analyzer for long periods. The
Analyzer automatically cuts off charging when the battery is fully charged. Before
use, check that the adapter voltage and frequency range match the local line power
range. To prevent decrease of batter capacity, charge it at least twice a year.
Before measurements, set the Analyzer according to the line voltage, frequency and
wiring configuration of power system you want to measure, read section "Set the
Analyzer" for more information.

5.3. Inputs

Picture: Connection to a 3-Phase system
The Analyzer has 4 BNC-inputs for current clamps and 5 banana-inputs for voltages.
For a 3-phase system, make the connections as shown in Figure 1.
First put the current clamps around the conductors of phase A (L1), B (L2), C (L3)
and N (neutral). The clamps are marked with an arrow indicating the correct signal
polarity.
Next make the voltage connections: start with Ground and then succession N, A (L1),
B (L2), C (L3). For correct measuring results, always connect the Ground input.
For single phase measurements, use voltage input A (L1) or current input A (L1) or
voltage inputs Ground.

5.4 Rapid Overview of Measuring Modes

This section provides an overview of all measuring modes. The screen information
and the use of function keys of the Analyzer will be explained in detail in the following
