Working pressure: 80 to 106 kPa

size :48x29x21 mm/1.88*1.14*0.82 inch

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

Package Included:

5* DC 100V 10A Voltmeter Ammeter Blue Red LED Dual Digital Volt Amp Meter Gauge
