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 the figure.
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.
