Connect up to eight analog input connections to the screw terminal connections labeled 
CH0 In through CH7 In. Refer to the 

 on page 4-6 for the location of 

these pins.  

You can configure the analog input channels as eight single-ended channels or four 
differential channels. When configured for differential mode, each analog input has 
12-bit resolution. When configured for single-ended mode, each analog input has 11-bit 
resolution, due to restrictions imposed by the A/D converter.  

When all of the analog input channels are configured for single-ended input mode, eight 
analog channels are available. In single-ended mode, the input signal is referenced to 
signal ground (GND). The input signal is delivered through two wires: 

ƒ

  The wire carrying the signal to be measured connects to CH# IN. 

ƒ

  The second wire connects to GND.  

The input range for single-ended mode is ±10 V, max, with a gain of 2. No other gains 
are supported in single-ended mode.

Figure 4-4. Single-Ended Measurement Connection 

 illustrates a typical single-ended measurement connection. 

 

To perform a single-ended measurement using differential channels, connect the voltage 
to an analog input with an even-number, and ground the associated odd-numbered 
analog input. This configuration is shown in Figure 4-4.
