measured in the suitable range by auto range mode
or manually. Now the "∆REL" key is pressed, the
display jumps to Zero, the following measurements
are displayed as +/- deviations.
Relative measurement with small capacitances
For small capacitor values at first a higher capacitor
is measured and fixed with the "∆REL" key. Now a
smaller capacitor is connected in parallel to the
higher and the difference value is displayed.
Auto Power OFF
The multimeter automatically switches off approx.
30 minutes after the last measurement, there is a
permanent sound.
