1. Seal off the pressure sensor input port.
2. Using the fine adjust knob, pressure-vacuum switch and internal pump, set the
calibrator to (approximately) the values in Table 65. Let the unit sit for one minute,
then record the displayed value.
3. Wait for one more minute, then record a second reading. The difference between the
first and the second reading is the leak rate.

718 1G
Maximum Leak Rate
-1.000 PSI
1.000 PSI 0.005 PSI/min
718 100G
Maximum Leak Rate
-10.00 PSI
3.00 PSI 0.10 PSI/min
The display should indicate:
0.000mA 0.00 PSI
1. Connect a test lead from Red AUX terminal of the 5520A to the Fluke 8508A I+
terminal.
2. Connect a test lead from Black AUX terminal of the 5520A to the Calibrator Com
terminal.
3. Connect a test lead from I- terminal of the Fluke 8508A to the Calibrator mA
terminal.
4. Adjust the 5520A if necessary so that the current shown on the Fluke 8508A is the
same as the 5520A values shown in Table 66.
5. Verify that the display readings on the Calibrator are within the limits.
