Display - Gigahertz Solutions NFA 30M Operating Manual

Made in Germany

3 Display

In general, the display will show the three dimensional ("re-
sulting") magnetic field. There is no need for a conversion:
Simply read the measurement value on the display and the
unit on the LEDs. The signal of an AC/DC input possibly
connected to the device will be shown in millivolt. Use the
key "^" to switch from one display mode to the other.
Special LCD Display Messages
"Low Batt": The rechargeable battery is low – please charge
the battery
"Err.": Short for 'Error'. Indicates an erroneous configura-
tion.
"----": No reliable values to be shown – either due to the in-
strument's transient effect, or the value is within the range of
the instrument's residual noise.
"CHAr": Instrument is being charged.
(For technical reasons the display will show "FULL" prior to loading, which is to
be ignored)
"FULL": During the charging process with the mains adaptor
connected, this indication means: charging completed, bat-
tery loaded. During normal operation, however, "FULL"
means the SD memory card is full.
"nbAt": The processor cannot recognize the battery (see the
note below)
The time indications are set up as follows:
"XXXd": XXX days or
"Xd.XX": X days and XX hours or
"XX.XX": XX hours and XX minutes
"XX.XX": (with blinking dot): XX minutes and XX seconds.
Elapsed time will be shown when switching on and while
logging.
Please note: when switched on, the NFA will normally show
the remaining battery life. However certain events may
cause wrong times, "00:00" or "nbAt" to be displayed. In
that case please leave the meter switched on for a few
minutes to perform its calibration algorithm, then switch off
and back on. It will now show the updated battery life for the
"Log" mode. Should the false readings persist, please check
chapter 9 for further information.
