Read the UUT Error: Resistance Output
To read the error of the UUT in the resistance function:
1. Set the necessary resistance output as described under “Set the Output.”
2. Use the output adjustment controls as necessary to achieve a reading on the display
(illustrated below) equal to the reading on the UUT. To adjust a higher-order digit,
push . As the reference value is approached, work progressively back towards
the least-significant digit on the 5730A Calibrator display as necessary by pushing
. It is only necessary to go one digit past the least significant digit of the UUT.

Introduction to Offset, Scale, and Linearity Errors
The performance of a DMM or meter can be plotted as a graph of input stimulus and
meter reading. For a perfect meter, the graph of the input stimulus would exactly match
the graph of the reading.
The 5730A Calibrator measures and shows three types of UUT errors:
• Offset Error
• Scale Error
• Linearity Error
