bayite Hall effect current meter reads current by detecting the magnetic field around the wire, there is no electrical contact which eliminate risk to delicate monitoring equipment and also minimizes safety concerns. The sensor doesn't get hot like the current shunt sense resistor which can have thermal temperature heat dissipation issues.

Three display modes:
1, alternately display Amps and Voltage
2, only display Amps
3, only display Voltage

Specifications:
Measurement Range: + -100A
Accuracy: + - 1%
Resolution: 0.3A
Working current: 7-15mA
Power supply: DC 5-120V
Product Dimensions: 48mm*29mm*23mm
Mounting hole: 45.5mm*25.5mm
Sensor hole diameter: 19mm
Operating temperature: -4°F - 140°F (-20°C - 60°C)

As the resolution is 0.3A, the current reading might be flickering with 0.3A difference. For example, if the current is 1.7A, you might see a 1.7A and 2.0A alternatively. This is normal.
If your signal is too weak or you are not getting the resolution you want, you can coil the wire through the current sensor as many times as you want to double, triple, or quadruple the sensitivity or resolution.
For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps.
