RANGE Function, Manual Measurement Range Selection

The RANGE function enables manual measuring range selection in some measuring voltages with an
automatic measuring range selection (AUTO). In threshold areas, the measuring range should be set
firmly to prevent undesired switching.
Press the "RANGE" button to activate this function. "AUTO" goes out in the display, and "MANUAL"
appears.
Press the "RANGE" button for 2 seconds to switch off this function. "AUTO" appears again in the display (if
the autorange function is available for his measuring range).

REL Function

The REL function allows a reference value measurement to avoid possible line losses which may cau-
sed e.g. during resistance measurements. For this purpose, the current indicated value is set to zero. A
new reference value is set. In the upper, small display, the basic value (rel difference) is displayed.
Press the "REL" button to activate this measuring function. The display indicates "
measuring range selection is deactivated now.
In order to switch off this function, press the "REL" button again or simply change the measurement function.
The REL function is not active in the measuring ranges for temperature, continuity
tests, diode tests, frequency, loop current and output.

MAX/MIN Function

The MAX/MIN function enables recording and displaying the maximum and
minimum values during measuring. When then "MAX/MIN" function is activa-
ted, the max or min value can be recorded, as selected. The current measured
value continues to be displayed in the small upper display. The figure shows
an example for the DC voltage measuring area.
By pressing the "MAX/MIN" button, the current measuring range is set (auto-
range is deactivated). The display shows the inverse symbol "MINMAX" and
"MANUAL". The currently measured value will be displayed.
Press again to switch on the MAX function. The max value is shown conti-
nually on the main display. You can recognise this value by the "MAX" sym-
bol. Press again to switch on the MIN function. The min value is shown conti-
nually on the main display. You can recognise this value by the "MIN" sym-
bol. Automatic measuring range selection is deactivated now.
To switch off this function, keep the "MAX/MIN" button pressed for approx. 2 s. The inverse symbol
"MAXMIN" goes out and the automatic measuring range selection is activated.
The MAX-MIN function is not available for all measuring functions.
