Range Function, Manual Measuring Range Selection - VOLTCRAFT VC-890 Mode D'emploi

j) AC voltage measurement with 1 kHz low-pass filter
Never use the low-pass filter option to test for the presence of dangerous voltages!
The voltages present could be higher than indicated under some circumstances.
Always measure voltage without the filter first to identify any dangerous voltages.
The DMM is equipped with an alternating current low-pass filter. This is an alternating current
measurement which is led through a low-pass filter in order to block unwanted voltages above 1 kHz.
Proceed as follows for AC voltage measurement with the
low-pass filter:
1. Turn on the DMM and select the measurement range
" V ". Press the SHIFT/SETUP button (3) to switch to the
measurement range "
2. Insert the red test lead in the °CHzVΩ measuring socket (7),
the black test lead in the COM measuring socket (8) (Fig. 10).
3. Connect the two test prods with the object to be measured
(generator, circuit, etc.). The measuring value is indicated on
the display.
4. After the measurement has been completed, remove the test
leads and turn the DMM off.
12. RANGE FUNCTION, MANUAL MEASURING RANGE
SELECTION
The RANGE function allows the manual selection of the measuring range in some functions with
automatic measuring range selection (AUTO). At the threshold areas, it is advisable to fix the
measuring range in order to prevent unwanted switching.
Press the RANGE (-) button (10d) to switch to the manual measuring range selection. The indication
"AUTO" will go out in the display (if the manual measuring range selection is selected).
Set the desired measuring range by pressing the RANGE (-) button repeatedly.
To switch back to the automatic measuring range selection, hold down the RANGE (-) button for 2 s.
"AUTO" will again appear in the display (provided the autorange function is possible in this measuring
range).
