Voltage Measurement
Resistive dividers are automatically changed to provide
in range readings for 200mV to 2000V full scale readings
(Figure 3-3). The input resistance is set by external
resistors R14/R13. The divider leg resistors are R9-R12.
The divider leg resistors give a 200mV signal VI
(Pin 44) for full scale voltages from 200mV to 2000V.
For applications which do not require a 10m
Ω input
impedance, the divider network impedances may be
lowered. This will reduce voltage offset errors induced
by switch leakage currents.
