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.
