Heke Tolerance
The tolerance modes are 1%, 5% and 10% respec-
tively for the Inductance, Capacitance and Resistance
functions. To enter this tolerance mode, insert the appropriate
component as a standard value into the socket or connect the
component to the test probes, then press the “TOL”
pushbutton to set this value as the standard reference
tolerance.
Similarly,
any
value
which
appears
on
the
LCD
display, such as DH or MAX/MIN/AVG, can be used as a
standard value to sort components. Press the key again to
cycle through 1%, 5% and 10% tolerance as desire.
This feature is designed for convenient component
sorting. An audible tone will beep three times whenever the
component under test exceeds the set tolerance. Conversely,
a single “beep” tones indicates the component under test is
within the set tolerance rate.
Notes:
1. The tolerance mode cannot be activated if the —
tested display is either “OL” or’0000"; nor can it
be activated if the tested capacitance value is below
10 counts. |
2. Tolerance mode is only available in manual
ranging; however, activation while in autoranging
will automatically set the meter to manual ranging
and cause calibration prompts to be displayed in
the recommended ranges.
3. The tolerance mode cannot be activated if the
meter is set at autoranging with data hold mode
activated.
