Select the device you want to calibrate. In the dialog box above, the Boosted system was labeled with a radio
button Ref3000-15116, so we select that device. Select the Both radio button to tell the system you want to
run both a DC calibration and an AC calibration. When you click the OK button, the Framework software
opens a runner window, and records current- and voltage-versus-time curves under a number of conditions.
If the calibration fails, you will see an Error window appear. If you see a failure, always suspect incorrect cable
connections first. An open fuse in the Calibration Cell causes calibration failures.
A service technician can use an ohmmeter to test for an open fuse in the Test & Cal cell. An
open fuse in the Cal side of the Test & Cal cell always causes AC Calibration failures.
Optional 30 A Test
If you wish to further test your system, you can switch the cell cabling to the Test side of the Test & Cal cell.
This side is a 3 mΩ 6 W resistor that will develop 90 mV at 30 A of applied current.
The connections are similar to the Cal side connections described above, but made on the Test side of the
fixture. Remember to move both the Counter and Working connections and the three Sense cable
connections.
Caution:
blow (open-circuit) the fuse.
Figure 3-3 shows the connections on the Test side of the Test & Cal cell.
