1.2v 12v ZB2L3 18650 Li-ion Lithium Battery Capacity Tester + Resistance Lead-acid Battery Capacity Meter Discharge Tester
- 140.00 EGP
- This circuit in order to improve the voltage measurement accuracy, specially designed DC bias, when the terminal is what all don't pick will display a small voltage, does not affect the actual measurement, if you are short connected with the input terminal (absolute 0V) will display 0. To understand the principle can consult the superposition theorem in electrical engineering.
