Variable resistor module provides higher accuracy
( 01 May 2008 )
|
· The 4-262 is an 18-channel variable resistor module designed to simulate the operation of PT100 and PT1000 RTD's with unprecedented resolution and accuracy in the PXI form factor.
· Provides resistance setting resolution of better than 10m over the entire resistance range and an accuracy of more than 0.1 percent for all resistance settings
· Uses innovative design principal that combines fine and coarse control mechanism in combinations with a calibration system to achieve quality performance
· Reduces effort in simulating variable resistance device, users can simply implement an interface to the simulator based on the known resistance versus temperature curve for their chosen sensor.
· Includes a calibration port that can be used to calibrate the resistor channels while the unit is connected to the UUT in a test system using an external DMM.
