NEW! Now with

• 0.42 OLED screen to show output no need to connect DMM to read output.
• BNC jack to connect directly to oscilloscope, less prone to noise then old 4mm banana jack connector.
• Micro USB charger inbuild.
• Supports 1x18650 Li-ion battery (Battery not Included)
• Auto power off (can be disabled and timer can be changed to OFF/5/10/20/25 min)
• Display can show +-1600mV in each range that corresponds to +-1600 nA/uA/mA with resolution of 1mV

This device is based on the open-source uCurrent standard design by Dave Jones from eevblog. It turns a normal Multimeter/oscilloscope into a precise nanoamp (nA)/milliamp(mA)/microamp(uA) level current measurement tool. This device puts very little burden voltage, while measuring current. The device basically consists of a shunt resistor and a precision op-amp.

To use the device, connect the load (device for which you want to measure current consumption) in series with current input terminals on the device. CurrentWave will convert current consumption into voltage with 1:1 mapping between conversion so it is very easy to read the reading eg: if CurrentWave is set in 1uV/uA range and the inbuilt multimeter is showing a reading of 50mV then with 1:1 mapping current consumption by the device would be 50uA).
