I'm hoping somebody can shine a light on this crazy scenario that I can not get passed right now.
I have a device that needs 3.6v to be powered on.
When I put a 3.6 battery straight to the device, it powers on as expected.
With my meter, I'm trying to measure the mA and uA usage of the device. The device's typical ON state current use is 100mA.
When I put the battery through the meter to test the current use, the device no longer powers on and the mA spikes I see on the meter reach 150mA.
However, when I use an adjustable power supply and set it to 3.6v and wire it exactly the same as I would the battery, the device powers on and I see almost exactly 100mA use.
I have replaced the batteries on my multimeter, replaced the croc leads from meter onto battery etc, but nothing makes a diff. What am I missing?
Why does the device power on when straight to battery, but not when wired through meter with battery. But meter works fine and device powers on when an adjustable power supply is connected?
Thanks in advance!!
