They can be connected in series at will to the positive, negative, or middle of the line to test current, but can only test current in one direction About Diverters Meters with a range of 20A or above must be connected to a corresponding 75mV shunt in order to work, even if tested at 0.1A, otherwise the instrument will burn out. The shunt is not included and needs to be purchased separately!!! 20A , with built-in shunt in the instrument, no need to purchase separately. Power supply DC power supply meter: supply voltage DC3.5-30V. The meter head adopts a common ground design, that is, the ground wire at the voltage measurement end and the ground wire at the instrument power supply end are common. No power supply required: 14-100V, 14-300V, 14-600V can be directly powered from the tested circuit This meter can only test forward voltage and current Specification Product model: YB103VA Product name: Guide rail type DC voltage and current meter Display method: 0.36 "LED, voltage red text, current green text <;30mA Measurement accuracy: 1% Measurement rate:>500mS/time Working temperature: -10~50 ° C Working pressure: 80-106kPa Working humidity: 10~80% (no condensation) Direct sunlight: no direct sunlight Relays ProductSiteLaunchDate : 2024-11-16T09:10:37.657Z Size : DC0-100V 50A UnitCount : 1
