Note

See Chapter 12, Probe Zero,

for additional information on the characteristics of

the survey system including the causes of zero drift.

•The field strength is not low enough. Move away from the RF field source, use the storage case to zero the probe.

•The probe is damaged. Try another probe.

To reconfirm the zero while the instrument is in use...

1.Establish a zero density environment for the probe as before.

2.Press the Auto Zero key. This will automatically “touch up” the zero and correct for any drift in a few seconds.

Measurement Display Screens

There are two display screen options:

•The Main Measurement Display Screen.

•The Alternate Measurement Display Screen.

Main Measurement Display Screen

The Main Measurement Display Screen shows a maximum value on the third line of the display. The Alternate Measurement Display Screen provides frequency-specific, real time information instead of a maximum value.
