Technical summary
Feature:
Cut-out size: 45mmx26mm
Dimensions: 48mmx29mmx21mm
Supply: DC 3.5-30V
Display: dual 0.28" three-digit LED tube
Refresh rate: about 500ms/time
Accuracy: ±1% + 2 digits
Voltmeter range: DC 0-100V (0.1V resolution)
Ammeter range: DC 0-9.99A
Note:
If you measure current above 5A for a long time, please solder the wires to the meter port, to avoid high impedance and unstable operation.
Wire connection:
Thin red wire (VCC): power supply + (DC 3.5-30V +)
(if the measured voltage is between DC 3.5-30V, then the thin yellow wire and the thin red wire can be connected together)
Thin black wire (GND): power supply - (DC 3.5-30V -), voltage measurement - (DC 0-100V -)
Thin yellow wire (VIN): voltage measurement + (DC 0-100V +)
Thick red wire (I+): current input +
Thick black wire (I-): current input -
