79. Set the output of the voltage source to 75 mV.
80. Query the reading every 2 seconds for 40 readings using the following
7.9.1.3.6 Reference Junction Ohms Range
81. Set the UUT in the RJ_OHMS cal range by sending the following commands
82. Connect a 10K Ohm resistor to the calibration cable connected to the UUT.
83. Query the reading every 2 seconds for 40 readings using the following
84. For all As Found data, calculate the average and standard deviation for each

1523/24 Alignment

Prior to performing the alignment, the following UUT configuration and control set-
tings must be set to the values indicated in the 1523/24 Alignment Settings table.
Caution: Failure to do this will cause large errors in the measurement readings
and invalidate the calibration.
