Fuse Current test:
Maximum load: 20A/48V DC for 10 seconds
Accuracy: ±2%, or 0.2 reading with a decimal point
Voltage test:
Test range: 1 to 48V
Accuracy: ±1% or 0.1 reading with a decimal point
The LCD indicates Err condition:
When the positive or negative pole is connected reversely
The tested voltage is less than 1V
When conducting voltage test, the resistance between the measured object is less than 1K
