Found on eBay, also available from various dealers on Aliexpress.
Power supply via "DC 12V" jack, the burden is connected to "Load" via Four wire measurement, Settings are changed with buttons 1-4, parameters are displayed on the display.
2: Down -
3: move cursor
Set cursor by button "3" to position "I/V", select "I". Set cursor to numericals and alter values by buttons "1" / "2″.
Setting voltage (lower voltage limit)
Set cursor by button "3" to position "I/V", select "V". Set cursor to numericals and alter values by buttons "1" / "2″.
Switch load on/off
Press button "4".
Press and hold button "4".
Select indicated values
Hold the button "3", at the same time press button "1" to select parameter. Button "2" resets display to "Auto", parameters are now displayed in sequence.
Buzzer on / off
Hold down button "3" while pressing button "4" at the same time to enable/disable the buzzer tone.
Adjust displayed voltage value
The setting shall be changed while having a load/battery connected. Press and hold button "3" until "Adjust mode" is shown on the display. Voltage then can be adjusted by buttons "1" and "2". Finally confirm with the button "4".
The following settings/functions are accessible by various key combinations when the device is powered on.
Display the software version
Hold buttons "1" and "2", connect the power supply. The version number - in this case "Edition 1.62", appears on the display.
CAUTION! This mode can make the device unusable when done wrong.
A power supply must be connected to the load connection which sources exactly 10V and 5.00A (current limit set).
Hold buttons "1" and "2", connect the power supply. The version number appears on display. Now press button "4" and enter the password using the keys "2" and "3". To do this, press both keys alternately until the calibration starts. Finally disconnect the supply.
For auto adjustment, a battery/rechargeable battery pack must be connected to the load, which provides less than 20V and can source more than 5A load current.
Hold the button "3", connect the power supply. The display will show "load V<20V A>5A - start to next". Press button "4" to start adjustment. Finally disconnect the supply.
"Fakes" are offered through the sources like eBay / Aliexpress lately, which are restricted in scope, measurement precision and can be potentially dangerous, because they do not reliably disconnect the load or deeply discharge connected batteries.
- the current is exceeded
- Low voltage termination limit is not always reliable
- displayed measured values are too high/low
- Calibration/adjustment cannot be done
- Different components
