Leds / Display / Audio Signals - Gigahertz Solutions NFA 1000 Operating Manual

3 LEDs / Display / Audio Signals

3.1 LEDs and Display
The measured value shown on the display ...
... is the unit adjacent to the solid green LED (primary measurement).
A flashing LED indicates the unit of the secondary measurement, which
can be selected by depressing the "Mode>" button .
In fields of very high magnetic intensity, the value will be displayed in uT
(microTesla), indicated by the red LED "X 1000". Also the green LED will
then turn red indicating a change of scale. Both LEDs will start flashing red when the
measured values are higher than the instrument can display. Similarly, when meas-
uring body voltage, a change from mV to V for higher values is indicated.
Special LCD Display Messages
"Low Batt": The rechargeable battery is low – please charge the battery
"Err.": Short for 'Error'. Indicates an erroneous configuration. This can occur when a
grounding cable or mains adapter is connected and potential-free E-field measure-
ment is selected. Select a different setting!
„----": Instrument is in the process of determining the measurement, or the value is
too small to be measured.
„CHAr": Instrument is being charged.
(For technical reasons "FULL" will be shown shortly before this, which is to be ignored)
„FULL": During the charging process, with the mains adaptor connected, this indi-
cation means: charging process completed, battery loaded. During normal opera-
tion, however, "FULL" means the SD memory card is full.
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 und XX seconds.
It will be shown upon switching on the NFA and when logging (see chapter 5.4).
Due to the increased power consumption (LEDs, sound signal, etc), the remaining
battery life in the operating mode "ON" is reduced by up to 30%.
