Hello John T,
You’re welcome.
Does “set voltage” mean Cut-off voltage of the battery and full-scale voltage settings?
If yes, here is the instruction of it:
Cut-off voltage of the battery and full-scale voltage settings
Step 1:Long press the “SET” button for 3 seconds to enter the battery cut-off voltage and full-scale voltage setting state, then release the button;
Step 2: After entering the state, voltage area flash to display the current battery cut-off voltage, and use the zero battery level symbol to indicate it is the cut-off voltage setting state; then you can shot press the button to add one, long press the button can add one quickly; the range of cut-off voltage setting is 2.8 ~ 29.9V, but not more than the full-scale voltage.
Step 3: When there is no key operation more than 3 seconds, it automatically enter into the full-scale voltage setting state;
Step 4: After entering this state, voltage area flash to display the current full battery level voltage, and use the full battery level symbol to indicate it is the full-scale voltage settings state; setting method is as same as the cut-off voltage; the range is 2.8V ~ 29.9V, but not less than the cut-off voltage.
Step 5: When there is no key operation more than 3 seconds, it will automatically save, if there is no error after saving it will quit automatically, if the value is incorrect or save incorrectly, it will display “Err SAu” for 1 second, and exit.
Hope this can help you.
Best regards
John T
