Signal connections
Analog input
You can connect up to eight analog input connections to CH0 IN through CH7 IN . Connect unused analog input
terminals to ground terminals during operation. For example, if you are not using terminal 15 ( CH7 IN ), connect
this terminal to terminal 16 ( AGND ).
The analog input channels are configured for single-ended input mode. Each analog signal is referenced to
signal ground (AGND), and requires two wires:
 Connect the wire carrying the signal to be measured to
CH# IN .
 Connect the second wire to
AGND .
The input voltage ranges are ±10 V, ±5 V, ±2.0 V, ±1.0 V.

For more information on single-ended inputs, refer to the Guide to Signal Connections (this document is
