DC 5~120V 100A Dial Current Voltage Amp Meter w Hall Effect r

Features:Through-hole design: No wiring diffity. Measure positive or negative current. No current direction limitationElectrically isolated from high voltage power source which eliminates risk to delicate ing equment and also minimizes safety concernsDisplay Voltage or (+ -)Current. Voltage Range: 5V-120V. Current range: 0-100ALarge wire capability: Diameter of the hole through r is 3/4 inch(19 mm)Loop through r multe times to strengthen signal. For example, if your current signal is only 0.2 Amps, you could loop the wire through the r 10 times and the signal would by 10X for stronger and would appear as 2.0 AmpsDescrtion:Hall effect current meter reads current by detecting the ic field around the wire, there is no electrical contact which eliminate risk to delicate ing equment and also minimizes safety concerns. The r doesn'for t get hot like the current s sense which can have thermal temperature heat diation iues.Three display modes:1. alternately display Amps and Voltage2. only display Amps3. only display VoltageSpecifications:Measurement Range: + -100AAccuracy: + - 1%Resolution: 0.3AWorking current: 7-15mAPower supply: for DC 5-120VProduct Dimensions: 48mm*29mm*23mmMounting hole: 45.5mm*25.5mmr hole diameter: 19mmOperating 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 the wire through the current r as many times as you want to double, tre, or quadruple the sensitivity or resolution.For example, if your current signal is only 0.2 Amps, you could loop the wire through the r 10 times and the signal would by 10X for stronger and would appear as 2.0 Amps.Note:We have more detailed manual, if you need an electronic r manual, please contact us.Package included:1x Dial Voltmete 1x Hall Effect r
