Description

Professional Precision Current Adapter for Multimeters

EUROPE: Simon’s Electronics now stocks the µCurrent in the UK, CLICK HERE to go to the shop.

So those in the EU should weigh up who it’s cheaper/easier/quicker to buy from. I ship from Australia and there are often customs hassles in the EU.

The µCurrent turns your multimeter (or oscilloscope) into a powerful and precise current measurement tool, from picoamps to amps.

Utilise the more accurate voltage range of your multimeter to measure precise current. Even expensive precise multimeters can be severely limited on their current ranges by the shunt burden voltage and tolerance.

Measure the standby and sleep current of the latest generation of microcontroller and other digital electronics, energy harvesting devices etc, down to the nanoamp (or even picoamp!) level with superb accuracy.

The µCurrent also works as a precision x100 voltage amplifier.

See my article originally published in Silicon Chip magazine about this project and explaining burden voltage.

Thousands of the original µCurrent are in use all around the world, and it has quickly become the industry standard low cost tool for low power current measurement in modern low power microcontroller based digital electronics. The µCurrent GOLD is the latest design with greatly improved specs over the original design:

  • 0.1% vs 0.5% on the mA range
  • 0.05% vs 0.1% on the µA and nA ranges
  • 300KHz bandwidth vs 8KHz bandwidth
  • +/-1.25A vs +/- 0.3A maximum current (& improved mA range burden voltage)
  • Shorting switch (useful when changing ranges, so you don’t break your circuit)

With the extra bandwidth you can now measure fast changing “sleep” modes in microcontrollers. The added shorting mode ensures uninterrupted power to your device under test whilst changing ranges. The µCurrent can rival 5 1/2 digit multimeters in accuracy, it is truly a precision instrument.

MADE IN AUSTRALIA!

Specifications

Current ranges

+/- 0-1250mA (20µV / mA burden voltage typical) * switch contact resistance plays a role here. 10uV due to the shunt resistor.
+/- 0-1250µA (10µV / uA burden voltage)
+/- 0-1250nA (10µV / nA burden voltage)

Output Voltage Units

1mV/mA, 1mV/µA, 1mV/nA

NOTE: You simply read your milivolt multimeter range as if it were mA/µA/nA

Resolution (nA range)

100pA (3.5digit meter)
10pA (4.5 digit meter)
1pA (5.5 digit meter)

Accuracy (typical)

<+/-0.05% on µA and nA ranges
<+/-0.1% on mA range.

Output Offset Voltage: <50µV (essentially insignificant on 4.5 digit meter)
Bandwidth:>300KHz (-3dB)
Temperature Drift: <10ppm / degC (µA/nA), <15ppm / degC (mA)
Noise: < -90dBV
THD: < -60dB
Battery: CR2032 Lithium coin cell Battery Life (NOT supplied): >50 hours (battery good LED ensures accurate measurement when LED is on).

NOTE

The unit is provided WITHOUT battery, it is not legal to ship these. You will need a standard CR2032 coin cell battery. Sorry about that, but I’m playing by the rules.

SHIPPING

Due to the irregularity and delays of the regular international mail system, and the customer expectation of tracking, I am now forcing the use of tracking for all orders. PLEASE NOTE that this tracking is NOT comprehensive like a couriers tracking system, it is pretty basic.

If you are in United Kingdom you can buy from SparkyLabs
If you are in Germany you can by from Welectron

    I bought an original uCurrent and it worked like champ. Bought the uCurrent gold and it’s so noisy that it’s unusable. No mechanism to get support or return it that I’ve been able to find.

    On a scale of 1 to Useful, this thing is an 11!

    What else on the market does the same job without costing at least an order of magnitude more?

    Please build more of these Dave, I need a spare for when mine gets lost or stolen 🙂

    I bought my uCurrent Gold about two years ago and it has been performing quite well on nA/uA power consumption measurements of my projects with low noise op amps and msp430 microcontrollers.

    It is a unique product that fulfills a gap in the market.

    Works great! The value for money is just amazing!
    When will you renew the stock? A friend of mine wants one as well.
