1. 999mA, 2A, 5A, 10A, 20A, built-in shunt.
2. If the current exceeds 20A, a shunt must be used to work, even if it is 0.1A, otherwise it will burn out.
3. For currents above 20A, the shunt is not built-in and needs to be purchased separately.

4. Because the floating charge voltage of a 24V battery after being fully charged may exceed 30V, it is "not" recommended to use a 24V battery directly.
5. In the following cases, it is strongly recommended to choose an isolated meter (isolated power supply meter):
(1) When two or more instruments are installed on one device. (2) When the power supply cannot be isolated.
Supply voltage: DC3.5~30V (Note: The maximum input voltage cannot exceed 30V, otherwise it will burn out.)
Display mode: 0.39" LED, red represents voltage, green represents current
Dimensions: 70 x 40 x 30 mm
Mounting opening: 68 x 38 mm
Measurement rate: 500mS/time
Measurement accuracy: 1% (±2 digits)
The negative pole of the power supply is connected to the test terminal and requires an independent power supply. It is not allowed for more than two instruments to share one power supply.
Wide power supply range with reverse polarity protection.
The voltage and current are displayed on the screen simultaneously.

Meter power supply: two-wire terminal
Black wire: negative pole of power supply.
Red wire: positive pole of power supply.
Test terminal: three-wire terminal
COM: Test common terminal (COM is the common negative pole of the voltmeter and ammeter)
V+: Test positive voltage input
A+: Test positive current input. It can only be connected to the negative pole of the load and the negative pole of the load power supply, as shown in the figure below.
For "20A or less", no shunt required:
