Low Imp. 400 Kω Function; Comparison Mode (Comp Mode) - VOLTCRAFT VC-890 Bedienungsanleitung

To turn off this function, press the MAX/MIN (View/►) button for approx. 2 s.
The MAX/MIN function is not available in all measuring functions.
16. LOW IMP. 400 KΩ FUNCTION
This function may only be used for voltages of a max. of 1000 V and a max. of 3
seconds!
This function allows the reduction of the measuring impedance from 10 MΩ to 400 kΩ in the voltage
measuring range. Reducing the measuring impedance suppresses possible phantom voltages which
could falsify the measuring result.
Press the -button (9) during the voltage measurement (max. 1000 V!) for a max. 3 seconds. After
release, the multimeter has the normal measuring impedance of 10 MΩ. While the button is pressed,
a signal sounds and

17. COMPARISON MODE (COMP MODE)

In the comparative measurement, once an upper and lower limit of the current measured parameter
is set, the main display will show only the actual status of the current measured value compared to
the preset range limit.
Proceed as follows to set the limit values for comparison mode:
1. Turn on the DMM and select the appropriate measurement range.
2. Insert the test leads into the correct measuring sockets.
3. Hold down the SHIFT/SETUP button (3) for approx. 2 s.
are now in SHIFT mode.
4. Hold down the SHIFT/SETUP button again for approx. 2 s to enter the SETUP menu.
5. To set the upper limit for the comparison mode, press the SHIFT/SETUP button until the menu
item "COMP MAX" is selected. An asterisk symbol * to the left of the menu item shows that the
menu item is selected.
6. You can now select the individual number of digits using the REL/PC (Log/◄) and MAX/MIN
(View/►) buttons and change their values with the H/LIGHT (+/COMP) or RANGE (-) button.
