The reading is calibrated to zero by relative function, when input is floating. Function Description 1. Operating Modes 1.1 Voltage Measurement A re-configurable voltage divider automatically provides a suitable range in voltage measurement mode. The following table summarizes the full-scale ranges in each configuration. Configuration Full Scale Range Divider Ratio Resistor Connection Input Pin VR1 220.00mV1 1 - V220m V.S. SGND VR2 2.2000V 1/10 R2 / (R1+R2) VR1 V.S. SGND VR3 22.000V 1/100 R3 / (R1+R3) VR1 V.S. SGND VR4 220.00V2 1/1000 R4 / (R1+R4) VR1 V.S. SGND VR5 2200.0V 1/10000 R5 / (R1+R5) VR1 V.S. SGND Note: 1. 220.00mV range is independent and manual mode. The input pin is different from other voltage ranges. 2. If VST is set to V- level, the auto range mode will start from 220.00V range. 2.2000V – 22.000V ranges only exist in manual mode. |
