Specifications

Analog Inputs
Number of channels 8 differential or up to 16 single-ended. Each differential channel can be configured as two single-ended channels.

Range
±2.5 mV to ±5 V

Resolution
0.06% to .33 mV

Accuracy
(0° to 40°C); .12% (-25° to +50°C)

Channel expansion
The Relay Multiplexer allows up to 64 single-ended channels to multiplex into four CR10X single-ended channels. A maximum of three multiplexers may be connected to one CR10X

Excitation outputs

Description
3 switched excitations, active during measurement, with one output active at a time. Nonactive outputs are high impedance

Output
±25 mA current, ±2.5 V range, .67 mV resolution

Period Averaging Measurements
Inputs Any of the 16 single-ended analog input channels may be selected for period averaging. Signal amplitude reduction or AC coupling is normally required
