With small dimensions (29 x 21 mm), wide measuring range (0-100v DC; 0-100A) and high percentage accuracy (± 1 digit))
Simultaneously displays voltage and current in different colors, red for voltage, blue for current (current is measured in the negative rail)
Requires external power supply; with reverse connection protection
The ground wire of the test end and the power terminal is the same wire; fast refresh about 500MS/hour
With integrated shunt, voltage and current calibration potentiometers
