3.3 Function Keys
”F-Func.“ (7) – Function Key
With this key you can switch between different function modi. In the
voltage measuring ranges you can manually switch between AC and
DC. On the left side of the display “AC” is shown for alternating voltage
and “DC” for direct voltage.
In the ”

functions. After turning the unit on, it is in the resistance measurement
mode. Press the key once to switch to the diode test mode, press twice
to reach the continuity mode with buzzer and press for a third time to
reach the resistance measuring mode again.
”R-Range“ (8) – Measuring Range Setting
When the unit is turned on it automatically switches to the set measur-
ing range. Sometimes it may be preferable to set the measuring range
manually. With the button you change the measuring range manually.
Proceed as follows:
1. Press the button ”R-Range“ and „Auto“ will be displayed.
2. After that, press the ”R-Range“ button until the intended measuring
range is displayed.
3. To return to the automatic mode, press and hold the “R-Range”
button for approx. 2 seconds. The display shows in the upper left
side the symbol ”Auto“ for automatic mode.
4. All key strikes are confirmed by confirmation beep.
“MAX-H“ (9) Maximum Value Memory
If you press this button before voltage measuring, the display shows
”M.H“. During measurement the highest value will be kept. To switch
this function off, press the button once more and “M.H“ will disappear
from the display.
