6.2 Power ON/OFF & Display Brightness
Press the Power key and a single beep can be heard, then the screen shows initial interface. Press the
Power key to cut off the power of the Analyzer under power on state.
The Analyzer provides 4 degrees of brightness, which is adjustable by pressing the brightness
adjustment key. Low brightness is suggested to save the battery power when powered by the battery.
6.3 Update Firmware
If any defective was found during the use of the Analyzer, please contact the customer service
representative to get the update pack.
Place the update pack under the root directory of U disk before making connection to the Analyzer.
Press the Power key, then press F3 to start update on seeing prompt information at the bottom of the
screen, do not operate the Analyzer during update process, or the Analyzer may be damaged and could
not work normally. The Analyzer will start properly if updated successfully.
If the update was failed, check the reason with the help of the prompt information on the screen. Cancel
the update by powering off the Analyzer if update was failed.
6.4 Input Connections
Check that the Analyzer setup meets the characteristics of the system under test. This concerns: wiring
configuration, nominal frequency, nominal voltage, current clamp ratio and range.
The Analyzer has 4 BNC inputs for current clamps and 5 banana-inputs for voltages. De-energize power
systems before making connections whenever possible, always use proper personal safety equipment.
For a 3-phase system, make the connections as shown in Fig. 2-5-1.
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 (GND) and then in succession N, A (L1), B (L2)
and C (L3). For correct measuring results, always connect the Ground (GND) input. Always double-
check the connections.
For single phase measurements, use current input A (L1) and the voltage inputs Ground, N (neutral) and
phase A (L1). The voltage inputs A (L1) is the reference phase for all measurements.
Before making any measurements, set the Analyzer up for the line voltage, frequency, and wiring
configuration of the power system you want to measure.
Scope Waveform and Phasor display are useful to check if voltage leads and current clamps are
connected correctly. In the vector diagram, the phase voltages and currents A (L1), B (L2) and C (L3)
should appear in sequence when observing them in clockwise direction as shown in below figure:
