Page 19: How To Update Dac Compensation File
To update the file, please follow the steps below: 1. Copy the file to the “C:\Whaleteq\” folder. 2. When the MECG 2.0 software is running, it reads the serial number of the connected MECG 2.0, and looks for the corresponding DAC compensation file. -

Page 21: Self-Calibration
±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. -

MECG 2.0 | User Manual Figure 11: Connection to a multimeter 3. Connect the multimeter to the RA and V1 jacks of the MECG 2.0 to measure the DC mV. It should be in ± 1% of 8.33 mV [V1 = V1 + (RA+LA+LL)/3 = 5 + (0+5+5)/3 = 8.33 mV] as the figure below. - Page 24 4. Repeat step 3 to connect the multimeter to the RA and V2, and then the V3 to V6 of the MECG 2.0 to measure the DC mV. All the V2 to V6 should be in ±1% of 8.33 mV.
