NOTE
– In resistance measurement mode, the multimeter will read a non-zero value
even when the two test leads are in direct contact, because of the resistance
of these leads. Use the Rel operation to zero-adjust the display.
– In DC voltage measurement mode, the thermal effect will influence the
accuracy. Short the test leads and press once the displayed value is
stable to zero-adjust the display.
