Refresh rate: about 300mS / times
Display: three 0.28" LED digital tube
Display color: A(red+red), B(red+blue)
Lead Length: 15cm
Dimensions: 48 x 29 x 22 mm, length X width X thickness
Opening Size: 46 x 27 mm
Net weight: 20g
Working Temperature: -10°C~65°C
Wiring:
Black line (thin): vacant or for buck circuit (module) negative
Red line (thin): positive pole of power supply
Black line (thick): COM, common measuring terminal
Red line (thick): PW+, input terminal of measuring positive voltage
Yellow line (thick): IN+, the positive of 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 for DC 4.5-30V
The ammeter can only be connected to the negative of the device under test and can only test amp in positive direction
Exceeds 5A, long-term full load working continuously, we recommended test side of leads directly soldered to the socket
When black thin line vacant, it is better to use insulating tape around exposed part of wire to prevent short circuits
If just used voltmeter, we recommended yellow line and black line connected together to prevent ammeter's digit flashing
Package includes:
1x Digital Volt/Ampere Meter
1x Current Shunt
