EDS 20H Hand-held Electrostatic Discharge
Indicators of power charger:
LED red ―Power‖(1): Steady light shows that the charger is ready for use. It lights once the
charger is plugged in.
LED red ―Charge‖(2): Steady light indicates the fast charging process after connecting the
battery pack.
LED green ―Ready‖(3): Steady light indicates the battery pack is fully charged. After
approx 2 minutes it switches to flashing, which indicates trickle charging.
Once the battery pack is connected, the testing cycle is initiated and the green LED flashes
for around 1 minute.
If it carries on flashing and the red LED ―Charge‖ does not light, it indicates that the battery
pack is not connected properly and maybe has an incorrect polarity.
LED yellow ―Discharge‖(4): Steady light indicates the discharging process after pressing
the yellow button. The LED ―Ready‖ flashes for around 1 minute indicating the testing
cycle.
Note: Discharge button (5): Press this button for about two seconds to start the optional
discharging process of the battery pack.
To avoid deep discharge, remove battery pack from EDS 20H when not using it for
more than one month.
To avoid deep discharge due to self-discharge, battery pack should be fully charged
at least once within a year, even if unit is not in use.
5.1.2 AC mains adapter (optional)
The optional AC mains adapter set can be used for powering the EDS 20H from the power
mains. To power the EDS 20H, replace the battery pack by the mains adapter and connect it
to the power supply output cable.
Special instruction: If finishing the test with mains adapter, please ensure a good earth
connection, or else, dangers may occur.
