Note
Position the probe in the case with one test point pointed downward and the other two test points above the foam. This will insure that the test points are not touching the foam.

7.Proceed with the probe zeroing process.
Zeroing the Probe
The probe and meter must be “zeroed” together. It is important that the probe is not exposed to radiated fields during the zeroing process. The storage case is shielded and provides a convenient “zero density” environment.
To zero the probe...
1.Place the probe in the storage case. Be careful not to move the probe while zeroing takes place (on probes with low frequency test points, you can create static which will give inaccurate results).
2.When you are ready, press the ENTER key. The screen will say ZEROING.
3.The meter will beep and the main measurement screen will appear in about 15 seconds after zeroing is completed.
If you get a message that the probe could not be zeroed, the most likely causes are:
•The probe is not connected properly. Check the connector and retry.
•The meter is set for a fiber optic input and you are using the standard cable input (or vice versa). Turn the meter off. Turn the meter back on and press
(F4) (MENU) to access the menu system. Press
8 (NEXT) to get to the Second Menu Screen. Press
3 (CABLE/FO) to the probe input status. Press F1 (OK) if it is correct or F4 to select the alternate. Then press Esc to return to the Opening Menu Screen.
