Executing Zero-Adjustment
1
Position the measurement leads in the actual measurement state.
Since the amount of zero adjustment varies with the position and state of the mea-
surement leads (probes) (i.e., their length, shape, position, etc.), the measure-
ment leads must be positioned in the actual measurement state before performing
zero adjustment.
These variations are particularly pronounced in the 3 m

and 30 m

ranges, so
be sure to position the leads in same state as will be used to perform actual mea-
surement when using those configurations.
2
Short-circuit the test leads together.
Proper zero adjustment is not possible with incorrect wiring.
Example: Model L2107 Clip Type Leads
