The circuit displayed on the center uses an external shunt resistor (~51.3 Ω) wired parallel to the input in order to measure current signals (e.g. 0-20/4-20mA).

The circuit displayed on the right side of the page uses an external resistor (Rx) to measure DC voltage (Vx). Rx and Rin (2K) form a voltage divider. The following table illustrates the applicable resistor Rx values for different DC voltages:

Vx	Rx	Vin
0..1V	0	0 -1V
0..5V	8K, 1/4W	0 -1V
0..30V	58K, 1/4W	0 -1V
0..60V	118K, 1/4W	0 -1V
0..100V	198K, 1/4W	0 -1V

Note: In case of low voltage measurements, use short and shielded wiring to avoid 50Hz (60Hz) line noise inteference.
