Ac/Dc; Range; Coil - Magnet-physik EF 14 Operating Instructions Manual

Electronic Fluxmeter EF 14
If the respective limit is exceeded the assigned relay switches. The relay contacts can be
accessed via the 25 pole socket on the rear panel of the instrument. You can find the pin
assignment in chapter 7.3.

4.7 AC/DC

The AC/DC key switches between the integration of alternating and direct voltages. You can
find detailed information about these operation modes in chapter 5.

4.8 Range

The Range menu allows the selection of the measuring range.
Fig. 4.8.1: Range menu
The selection window is opened with the Range key. The range that is actually active is shown
inversely. Selection is carried out using the arrow keys. Press Enter to confirm the new
selection or Escape to return to the measuring operation discarding any changes.
-4 -5 -6
For almost all occurring measuring tasks the measuring ranges 10 Vs, 10 Vs and 10 Vs are
-7
sufficient. The measuring range 10 Vs should only be selected if really necessary. The
unavoidable drift, especially over a longer measuring time, is considerably stronger here.
In the two lower lines you can see the maximum value that can be measured and which lowest
-4
resolution is available. In the 10 Vs range the EF 14 can measure 225.0 mVs at maximum. In
-7
the 10 Vs range the resolution is 0.1 µVs. Beside you can see the values in the currently
selected unit that correspond to these flux values.
If the maximum reading of the currently selected range is exceeded in measuring operation, the
display starts to blink and the maximum measurable value is shown. In this case select a less
sensitive range.
