This range of programmable resistor modules feature high setting resolution with excellent stability and accuracy through the use of innovative switching networks and software correction techniques. This also means all resistance values can be set - there are no missing values due to switch resistance or resistor tolerance.
They are ideal for sensor emulation applications that require very fine adjustment and also have the capability of being set as open or short circuit to simulate faults in cabling systems. The range includes modules specifically designed for RTD and strain gauge simulation.
Some modules incorporate a calibration port for connection to a DMM to assist in the confirmation of the module’s performance. Calibration can be performed with the UUT connected to the module and multiple modules can be cascaded and calibrated with a single DMM (this does not apply to the 40-297 which uses the same connector for the UUT and calibration).
The resistor channels and calibration port occupy separate connectors on the module’s front panel. All connectors are supported by a comprehensive range of cable and connector accessories.
New versions of the precision resistor cards are being regularly introduced, please contact your local sales office for more details.
