NOTE!
Display of symbols indicates that the tested object is live. The
measurement is blocked. The meter must be immediately disconnected from the
object.
If the Autozero option was not deselected, (steps ), the meter invariably
reduces the measurement result by the resistance of the connected test leads.
Then, for each change of the leads, the Autozero procedure must be repeated.
The correction factor is also remembered after restarting the function and/or the me-
ter.
If the test leads have been changed to such of a lower resistance than the previous
ones but the Autozero procedure has not been performed, the meter will under-
state the value of the measurement. In extreme cases, the meter may indicate a
negative resistance. Similarly, greater resistance of the leads causes an over-
stated result of the measurements.
