Performance Tests for the 15B+ and 17B+ 
Before doing the performance test, make sure to warm up the calibrator. 
To test each function and operating ranges: 
1.  For each step in Table 3, set the UUT to the specified function and range.  
2.  Connect the source to the input jacks on the UUT. 
3.  Apply the output from the source. 
4.  Make sure the readings on the UUT display are within the limits in Table 3.
