7 / 26 page V 1.5 7 2015/12/11 ES218 2000 Counts Manual DMM Function Description 1. Operating Modes 1.1. Voltage Measurement A re-configurable voltage divider provides a manual range in voltage measurement mode. The 200.0mV range is independent and manual mode. It takes input signal from mVin (pin22). The other ranges take the input signal from VR1 (pin21). The following table summarizes the Full-Scale ranges in each configuration. Configuration Full Scale Range Divider Ratio Resister Connection Input Pin VR1 200.0mV 1 - mVin V.S. SGND VR2 2.000V 1/10 VR2 (1.111MΩ) VR1 V.S. SGND VR3 20.00V 1/100 VR3 (101KΩ) VR1 V.S. SGND VR4 200.0V 1/1000 VR4 (10.01 KΩ) VR1 V.S. SGND VR5 1000V 1/10000 VR5 (1KΩ) VR1 V.S. SGND The ES218 support the hazardous live voltage warning. When the voltage measured exceeds the 30V, the buzzer generates 2KHz beep and ALARM (pin38) drive high output (V+ level) periodically. It can remind the user to notice the hazardous voltage. The buzzer sound warning could be cancelled by DISDGBP (pin41). 1.1.1. OL Selection ES218 has a voltage OL selection feature archived by configuring the pin CESEL (pin40). In 1000V voltage mode, ES218 will show OL when the voltage is exceed the overflow level. If CESEL is connected to DGND, ES218 will have a 1010V overflow level in voltage mode. If CESEL connected to V-, the overflow level will be set to 610V in DCV and ACV mode. The configuration of CESEL is listed below. For ACV/DCV voltage modes: CESEL V- DGND Floating DCV 610V 1010V 1010V ACV 610V 1010V 760V |
