NARDA 8718B - Manual (Page 19)

18 Operating the Meter
• 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.
See Chapter 12,
Probe Zero,
for additional infor-
mation on the char-
acteristics of
the survey system
including the causes
of zero drift.
