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 Resister Connection VR1 110.00mV 1 R1 VR2 1.1000V 1/10 R2 / (R1+R2) VR3 11.000V 1/100 R3 / (R1+R3) VR4 110.00V 1/1000 R4 / (R1+R4) VR5 1100.0V 1/10000 R5 / (R1+R5) Note: 110.00mV range only exists in manual mode. 1.1.2 CE selection ES51911 has a CE selection feature archived by configuring an CESEL pin. If pin CESEL is connected to DGND or floating, ES51911 will have a 610.0V overflow level in DC and AC 1100.0V ranges. If pin CESEL is connected to V-, ES51911 will have a 1010.0V overflow level in DC and AC 1100.0V ranges. The meter will Show OL when the measuring signal reaches the overflow level. The configuration of CESEL is listed below. CESEL DCV ACV V- 1010.0V 1010.0V DGND or floating 610.0V 610.0V |
