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. Connect your multimeter across voltage output terminals for the device. Set the multimeter in voltage range (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 multimeter is showing a reading of 50mV then with 1:1 mapping current consumption by the device would be 50uA).
• 3 Current ranges:
+/- 0-300mA (70µV / mA burden voltage typical)
+/- 0-1000µA (10µV / uA burden voltage)
+/- 0-1000nA (10µV / nA burden voltage)
• Output Voltage Units:
• Resolution (nA range): 100pA (3.5digit meter), 10pA (4.5 digit meter)
• Accuracy (typical): <0.2% on µA and nA ranges, <0.5% on mA range.
• Output Offset Voltage: Negligible on 4.5 digit meter
• Bandwidth: 2KHz nominal (+/-0.1dB)
• Temperature Drift: Insignificant over the normal ambient range
• Noise: < -90dBV
• THD: < -60dB
• Battery: CR2032 Lithium coin cell
• Battery Life: >200 hours (LED OFF), >50 hours (LED ON)
• Connection: 4mm banana, screw terminal inputs, standard 19mm spacing
