9 / 32 page  v2.6 9 08/10/06 ES51969 6,600 Counts Auto DMM 1.2 Resistance Measurement A re-configurable divider automatically provides a suitable full-scale range in resistance measurement mode. The following table summarizes the full-scale ranges and the reference resistors in each configuration. In 66MΩ range, the resolution is 0.1MΩ, if SHIFT is floating or connected to DGND. It will be changed to 0.01MΩ, if DSHIFT is pulled to V-. Configuration Full Scale Range Relative Resistor Equivalent value OR1 660.0Ω OR1 100Ω OR2 6.600KΩ VR5 1KΩ OR3 66.00KΩ VR4 10KΩ OR4 660.0KΩ VR3∥VR1 100KΩ OR5 6.600MΩ VR2∥VR1 1MΩ OR6 66.00MΩ VR1 10MΩ 1.3 Current measurement for multimeter ES51969 has 2 automatic and 1 manual current measurement modes for multimeter. The following table summarizes the full-scale range of each mode. When ES51969 operates in the current measurement modes for multimeter, It takes high input from pin IVSH or IVSL, low input from pin SGND and reference voltage from pin VR. Mode FC1~4 2VBAR Full Scale Input Terminal Automatic1 1,1,0,1 1 660.0µA / 6600µA 3IVSL/IVSH V.S. SGND Automatic2 1,1,1,1 1 66.00mA / 660.0mA 3IVSL/IVSH V.S. SGND Manual 0,0,0,0 X 66.00A IVSH V.S. SGND Note: 1. Connect VBAR to V- will disable the “µ2” / ”m2” symbol on LCD panel, so in the mV range of voltage measurement, this pin must keep floating. 2. The typical connection of input terminal is as the schematic below: *The voltage results from the current flows through resistors R and 9R. Its input range is up to 3.3Vrms. 1.4 Current measurement for clampmeter ES51969 has 2 automatic and 4 manual current measurement modes for Clampmeter. The following table summarizes the full-scale range of each mode. When ES51969 operate in the automatic mode1&2, it takes high input from IVSH/IVSL (higher range/lower range), low input from SGND and reference voltage from VR. When ES51969 operate in the manual mode1~4, It takes high input from ADP, low input from SGND and reference voltage from VA+ and VA-. IVSL IVSH Vin* 9R R 100K 100K |
