QuickCharge detection

The meter automatically recognizes devices with QuickCharge support. 

The following QuickCharge modes are currently supported:

QC2.0. QC3.0, Apple 2.4 A / 2.1 A / 1 A / 0.5 A, Android DCP, Samsung

Recording of charging process

Voltage of 

D+ (DP)

Voltage of  

D- (DM)

Mode indicator

Accumulated  

electrical loading

Accumulated 

energy

Total 

accumulation 

time

Trigger current

for recording

Recording indicator

Red

: Recording paused

Green

: Recording in process

After power is turned on, if the flowing current is greater than the trigger 

value, the system automatically starts recording the 

accumulated electrical charge, energy and elapsed time. The „REC“ indica-

tor then changes from red to green.

To set the current trigger value, press  

 

 

and hold it to 

highlight the value. Press    

 

to adjust the value accordingly. 

The value can be set anywhere between 0.01 A and 0.3 A.
