Setting the standard reference tolerance (Tol%)
The tolerance ranges available are 1%, 5%, 10%, and 20%.
To enable the tolerance mode, insert an appropriate
component as a standard value into the component socket or
connect the test clip to the component leads, then press the
key to set this value as the standard reference tolerance.
Similarly, any value which appears on the display, such as
Hold or Max/Min/Avg (Rec), can be used as a standard value
to sort components. Press again to cycle through 1%, 5%,
10%, and 20% tolerance as desired.
This function is designed for convenient component sorting.
The beeper will beep three times whenever the component
under test exceeds the setting tolerance. Conversely, when
the beeper beeps once, this indicates that the component is
within the setting tolerance.

• The tolerance mode cannot be activated if is shown on the display
or when the tested capacitance value is below 50 counts.
• Tolerance mode is only available in manual ranging; therefore,
activation while in autoranging will automatically set the LCR meter to
manual ranging.
