Display / Leds - Gigahertz Solutions NFA 30M Operating Manual

Made in Germany

3 Display / LEDs

When switched to "On", the NFA will briefly show "bAtt" and the re-
maining battery life. When switched to "Log", the remaining
battery life is shown cyclically with the elapsed log time and name of
the log file. After some self-tests the measurement starts automatically.
Time indications are set up as follows:
„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.
Two days is the specified minimum logging time ("2d00"). The real ca-
pacity can be higher, in particular with new batteries.
Status LED
The "Status" LED indicates the current mode of operation
"Red" indicates special operating conditions. Do not switch off while
the Status LED is red!
"Yellow" means "measurement in progress, NO recording".
"Green" means "measurement in progress WITH recording",
Note: with the switch set to "Log.", the "Status"-LED is switched off after a short while,
in order to extend battery life.
