2 Operation of the analyzer

2.1 Buttons

The keyboard of the analyzer consists of four buttons: ON/OFF , LEFT , RIGHT

, START/STOP . To switch-on the analyzer, press ON/OFF button. Directional buttons

LEFT and RIGHT are used primarily to change the information screens. The screens change circu-

larly, i.e. after pressing RIGHT button, when 9/9 screen is displayed, the device goes to screen 1/9.

After pressing LEFT button, screens are displayed in reverse order. START/STOP button is used

to start and stop the recording as defined in the configuration of current set point.

2.2 Switching the analyzer ON/OFF

 The analyzer may be switched-on by pressing button . Then a welcome screen is

displayed, showing the name of the meter, the internal software version (firmware), hardware

version and serial number. Then, the analyzer performs a self-test and in case of detecting

errors, the display shows an error message, accompanied by a long beep. When an error occurs

during memory card launching, the following message is displayed "Memory card error". If the

file system on the card is damaged (e.g. when the user manually formatted the card as mass

storage memory accessible only for the user) the analyzer will suggest formatting the memory

(message "Format memory card?") and button will trigger the process of formatting (3

short beeps). After the formatting is completed, the analyzer will repeat initialization of the card.

 When during the card initialization, the analyzer detects FIRMWARE.PQF file in the root

directory, which includes a newer version of the firmware (internal software), the upgrade

process will be suggested by the analyzer by displaying message "Update firmware?". Button

triggers this process (3 short beeps) and its progress may be observed on the display.

The update may be skipped by pressing the briefly button . When he update is

successfully completed, message "Update successful!”, will be displayed or in other case

"Update Failed!”. Then the analyzer will automatically switch-off.

 After switching on, the analyzer is activated at the last measurement point and displays 1/9

screen with a phasor diagram.

 To switch the analyzer OFF, keep button pressed for 2 seconds, when no button or

recording lock are active.

 Pressing the active button results in a short beep of a higher pitch; for inactive button the beep

is longer and at a lower pitch.

 Pressing button or for at least 1.5 s refreshes the display.

2.3 Auto-off

When the analyzer operates for at least 30 minutes powered by the battery (no power supply

from mains) and it is not in the recording mode and PC connection is inactive, the device automat-

ically turns-off to prevent discharging the battery.

The analyzer turns off automatically also when the battery is fully discharged. Such emergency

shut-down is performed regardless of the mode of the device. In case of active recording, it will be

interrupted. When the power supply returns, the recording process is resumed. Emergency shut-

down is signalled by message "Battery discharged!".
