Made in Germany

3 Display

In general, the display will show the three dimensional ("resulting")
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 configuration.
„----": No reliable values to be shown – either due to the instrument's transient ef-
fect, 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 indi-
cation means: charging completed, battery loaded. During normal operation, how-
ever, "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 dis-
played. In that case please leave the meter switched on for a few minutes to perform
its calibration algorithm, then switch off and back on to display the updated battery
life for the "Log" mode. If case the false readings persist, please check chapter 9 for
further information.
