I eagerly connected up my new ucurrent. Config rigol bench supply on 5v . A 2k2 resistor in series with the ucurrent and back to bench supply. The ucurrent switched on and range switch on mV/mA.
Measured mV output of ucurrent with fluke 87 V and it is unstable ie moving around and incorrect . I expected to see 2.27 mV but it jumps around 4.5 mV .
Any feedback as to wether this product is any good .
