±1%. Since no minimum limit is stated (and it is impossible to apply ±1% for very small voltages), WhaleTeq has applied a rule of 20% of the EUT limit. This is effectively ±5µV for up to 500µV, ±8µV from 500 to 800µV and ±1% for values above 800µV. -

2. Connect a multimeter to the RA and LA jacks of the MECG 2.0 to measure the DC mV. It should be in ±1% of 5 mV as the figure below. The MECG 2.0 output amplitude gives alternating 5s (0.1 Hz square wave) phases at -2.5mV and +2.5mV, so set the multimeter to zero (delta function) at one phase (e.g.:... -
