Max./Min. Menu
The
Max./Min.
function allows capturing maximum and minimum values.
Fig. 7: Max./Min. menu
If
Absolute
is selected, the maximum is shown in the line below the measured value. The
maximum is the highest reading that was captured since the
Reset
key was pressed last. When
this maximum is evaluated, the sign of the reading is not taken into account.
If
Max./Min.
is selected, the maximum, the minimum and the difference between maximum and
minimum are shown in the line below the actual reading. The maximum is the highest reading
that was captured since the
Reset
key was pressed last. The minimum is the lowest reading that
was captured since the
Reset
key was pressed last. Here in DC mode the sign of the readings is
taken into account.
The
Reset
key deletes the captured values. These are also reset if the device is switched off, if
the signal mode is switched between
AC
and
DC
and if the device enters standby. The
Max./Min. function can be used together with the relative function.
The
Max./Min.
function is designed to observe slowly changing signals. A change in the
magnetic field, that is not visible in the display, cannot be captured. The
Max./Min.
function
should not be confused with a fast Peak function of more sophisticated measuring instruments.
In the following cases the function is particularly useful:
•
Measuring very inhomogeneous fields, for example on the surface of magnets. Here
often only the measurement of the maximum value is sufficiently reproducible.
•
To capture readings in hard to get at places.
•
To display the maximum field when field orientation is unknown. The probe is rotated
slowly and the largest value will be captured.

Limit Menu
If the
Limit
function is enabled and the measured value is larger than the upper limit level,
High
will be displayed. If the measured value is smaller than the lower limit level,
Low
is displayed
(see Fig. 3). If the measured value is in between,
OK
is shown.
