• Minimum resolution (A): 0.01A
• Operating temperature: -15 to 70° c
• Working pressure: 80 to 106 kPa
• size :48×29×21 mm

Wiring:

• Black line (thin): vacant or buck circuit (module) negative
• Red line (thin): power supply+
• Black line (thick): COM, common measuring
• Red line (thick): PW+, measuring terminal voltage input positive
• Yellow line (thick): IN+, current input+ (Please refer to the wiring diagrams for more details)

Notice:

• the voltage between the thin red and thin black lines must be within DC 4.5-30V
• the ammeter can only be connected to the negative of the device under test 10A below ammeter (include 10A), built-in shunt, does not require external shunt
• when the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
• if just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing
