hi, I've just started using my uCurrent. The version is Rev 5.
Circuit I am using is a simple 3V CR2032 with a 15k resistor.
The 3v battery measures 2.96v , and measuring the circuit with the DMM I get 0.196 mA current, which is good.
My cheap DMM have display up to 199.9 and therefore my mV range will read up to 200mV.
However, when I use my uCurrent (Batt OK light is on) I have the following issues:
1) in the mA and uA range with nothing connected to the current input
, my DMM in mV range reads -2.4 . In the nA range it reads 0.
2) with uCurrent in mA range, I connect the circuit with 3v battery and 15 k resistor in series to the
uCurrent current input. Dmm reads -25.8 , which is nothing like the 0.197mA measured with DMM alone.
am I using this device incorrectly ? please advice.
I have also tried several new cr2032 batteries, they all yield the same result.
