2. If the current exceeds 10A (except for 20A direct test), a shunt must be used to work, even if it is 0.1A, otherwise it will burn out.
3. For currents above 10A (except for 20A direct test), the shunt is not built-in and needs to be purchased separately.

(2) If you do not have a shunt, please order the corresponding shunt
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.

1. Standard: DC3.5～30V (Note: The maximum input voltage cannot exceed 30V, otherwise it will burn out.)
2. Isolation meter: DC8-18V
Display mode: 0.28" LED, single or dual color:
(Red-Red): Voltage and current are both red.
(Red and Blue): Voltage is red and current is blue.
Installation opening: 45.5*26.5 mm
Measurement rate: 500mS/time
Measurement accuracy: 1% (±2 digits)

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 (black line): test common terminal (COM is the common negative pole of the voltmeter and ammeter)
V+ (red wire): test positive voltage input
A+ (yellow line): Test positive current input. Only connect to the negative pole of the load and the negative pole of the load power supply, as shown in the figure below.
For "above 10A", a shunt is required:
For "10A or less", no shunt required:

For 20A direct test only:
