6.6 Test Electric Level
SM6015A handheld LCR Meter uses AC signal applied to the item measured (DUT)
to test. The level is the amplitude of the AC signal and it is 0.6V.
6.7 Tolerance Mode (TOL)
The tolerance mode is specifically used for component sorting purposes. In tolerance
mode, secondary display indicates the range of percentage.
Tolerance mode, nominal value and sorting limit just come into play on primary
parameters. The selectable
range for sorting is as follows: 1%
，
5%
，
10%
，
20%. In tolerance mode, the data
indicated in the primary display will be recorded as nominal value.
Displayed value in percentage: =100*(Mx-Nom)/Nom%
Where, Mx: the primary parameter display; Nom: the nominal value recorded.
The percentage value is used for sorting.
Use Tolerance Mode
To use the tolerance mode as the process shown below:
1. Select the desired primary measurement mode by pressing L/C/R/Z button.
2. Configure the proper test frequency and series/parallel equivalent mode.
3. Perform the operation of CLEAR appropriately if necessary.
4. Test standard implements or components with accurate and reliable measured
value.
5. Once the desired measured reading is displayed, press the TOL button once to
store the reading as the nominal value. At this point, the “TOL” will be displayed
on the screen, indicating that the tolerance mode is activated. A percentage
mode will be shown in the secondary mode to indicate the percentage range.
NOTE:
Before the press of
TOL
button, the
primary parameter indicated on LCD
in any mode can be taken as the nominal value, including data hold, MAX, MIN,
AVG data recording, etc.
6. If sorting is not necessary, you can skip this step. If it is necessary, by pressing
the TOL button you can select the range of 1%
，
5%
，
10% or 20%, which will be
shown on LCD accordingly.
7. Changing test component, an audible tone will be heard. One single “beep” or
tone means the component is within tolerance. Three “beeps” or tone means the
component is out of tolerance.
WARNING: Be sure that the capacitor has been fully discharged before its test,
or the instrument might be damaged.
Disable Tolerance Mode
Long press of TOL button will disable tolerance mode.
NOTE:
Changing the test frequency, primary function,
or secondary function will
automatically disable tolerance mode.
6.8 Auto LCR Mode
Auto LCR function will automatically select the corresponding primary and secondary
parameters and suitable series/parallel equivalent mode of L, C, R. The selection is
done by judging the impedance property of component according to the test result. It
is quite convenient for the measurements of mixed and unknown components.
