number of the module you are running the Auto-Adjust Routine for. Then press Hz to continue.
A2 EXAMPLE: The Module Cal ID number is similar to the instrument serial number but
appears on the modules. The A2 Module Cal ID number can be found on the ribbon cable
connector at the left hand side of the A2 board you will see a label with a number similar to:
2412A/31458. So, you would enter [3] Q] [4] [5] [jj] [Hz] for the Module Cal ID number.
13. Now the printer should respond by printing out the statistics of the module. See Figure 5-1. All
the information on the print out has been discussed previously, except the Calibration Method
number, which will be discussed in Interpreting Cal Data Stats later in this section.
