Signal connections
Analog input
You can connect up to eight analog input connections to the screw terminal containing pins 1 to 20 (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).
All analog input channels are configured for single-ended input mode. All analog input signals are referenced to
ground (AGND):
 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 about analog signal connections
For more information about analog input connections, refer to the OMB-DAQ-2400, OM-USB,
OM-WEB, and OM-WLS Series General Guide to Signal Connections (available on our web site at
www.omega.com/manuals/manualpdf/M4830.pdf).
Channel-Gain queue
The channel-gain queue feature allows you to configure a different gain setting for each channel. The gain
settings are stored in a channel-gain queue list that is written to local memory on the device.
The channel-gain queue list can contain up to eight unique elements. The channel list must be in increasing
order. An example of a five element list is shown in the table below.
