As-Active-Probe - Projekt Elektronik FM 302 Operating Manual

5. Description
Additionally an amplification to one-tenth of the measurement range can be
activated. The created chart can be saved in different graphic formats.
The control software do not just allow to display the measured values of the
FM 302 but also allows to save them into a log file. For this two different
modes are offered. In the mode "single value logging" single measured
values can be saved with a key press (mouse or keyboard). This mode is
suitable for manual controlled measurements where a number of single
values has to be measured. Otherwise in the mode "continuous value
logging" the measured value are automatically stored continuously into the
log. This mode is suitable to record traces over longer periods of time.
For storing there can be chosen from two different formats. The log can be
saved in classic csv format (comma separated values) where the single data
blocks are separated by a comma and the period is used as decimal
separator. Alternatively the semicolon may be used for separating the data
blocks which makes available the comma as decimal separator. This
settings simplifies the import into software with German localization.
As another function the software offers a limit comparator. An upper and a
lower limit may be entered. The software shows if the current measured
value is below the lower limit, between both limits or above the upper limit.
This function allows e.g. the quick incoming inspection of permanent
magnets.
The polarity can be ignored while checking the compliance with the given
limits. Additionally the set limits can be displayed in the oscilloscope-like
display.

AS-Active-Probe

The AS-active-probes are active probes to measure the magnetic induction.
In contrast to most other available probes, the AS-probes contain an active
electronic so that a calibrated analog signal is available at the plug.
The transverse probe made of glass fiber fabric (AS-NTP 0,6) with their
slight thickness make it possible to measure in narrow air gaps and difficult-
to-reach locations. For transportation the probe is protected by a cap.
Further-more the probe carrier is temperature resistant up to 100 °C.
