Configuring the Instruments
Once you have entered the instruments traceability information, you must verify the
instruments’ configuration, to ensure the calibration system communicates properly.
1.
Open the MET/CAL Editor. Select Tools/Edit Configuration (or press F12) to open
the Edit Configuration dialog box. Fill in the dialog box as follows:
•
Select the Fluke 5500A if it is already configured. If it is not configured, select
Add; then select Fluke 5500A in the drop-down list. Type in the same asset
number you entered for the traceability information.
•
Choose IEEE-488 as the remote interface, and enter the address, if necessary.
The factory default is 4.
•
Under Extended Performance, click the box next to 5500A/EP so it contains an
‘x’. Then click OK.
2.
Repeat for the HP 3458A. The IEEE-488 address default is 22. If you change these
addresses, be sure you use different ones for the Fluke 5500A and the HP 3458A.
3.
Repeat for the Fluke 5500A/EP. For this instrument, you will need to type “Fluke
5500EP” in the top field. Then select the following parameters:
•
Choose Serial as the remote interface.
•
Choose COM5500 as the port.
•
Enter the alias as 5500EP.
Installing the Verification and Adjustment Procedures
Place the 5500A/EP disk into disk drive A or B, and select File/Run from the Program
Manager. Type “a:setup” or “b:setup” and click OK. Follow the on screen prompts.
When the “Select Calibrator Dialog” is displayed, select “All”. Install all procedures
displayed in the “Procedure Selection Dialog”. Procedures are installed in compiled form
and are ready to be executed from the Run Time.
The Switch Accessory
The switch accessory handles all analog outputs that are sourced by the 5500A,
operating according to remote commands sent over the 5500A serial bus. It contains
shielded test leads, an internal 4-wire ohms short, and a 0.01
µ
F capacitive filter for
high-resistive measurements that may require extra noise filtering.
The switch accessory operates as a routing accessory between either of the two sets of
instruments listed below:
•
The 5500A and the Hewlett Packard 3458A for characterizing the 5500A.
•
The 5500A and the DMM you are calibrating.
Warning
Lethal voltages can appear on any one of the switch
accessory’s terminals. To avoid electrical shock, never operate
the switch accessory unless all leads are connected to an
instrument according to the instructions in this manual.
