Method Two:
Step one: the same as method one
Step two: move the cursor to the tolerance through the left and right direction keys, short press the
key to enter the custom tolerance interface (-50.00% ~ +50%, resolution 0.01%). The
setting method can refer to the custom setting of frequency.
(4) Sorting mechanism
P1, P2 and P3 are used to indicate whether the main parameter is qualified or not. If it is not
qualified, then OUT flag will be displayed on the Interface of Measurement Display (in the case of
turning on the comparator); then the sorting is completed. If it is qualified, P1~P3 will be
displayed 1/2/3 in the measurement display, and continue to execute secondary parameter
comparison. If the secondary parameter is set, and the secondary parameter is not in the range, it
will be displayed AUX.
AUX is used to indicate whether the secondary parameter is qualified or not. If the primary
parameter is qualified, then unqualified secondary parameter will be displayed on the AUX
display.
If one of the main parameter and secondary parameter of NG is not qualified, it will be
displayed OUT as shown in Fig.4-7
The comparison process is as shown in Fig.4-8:

Note:
If you want to save the current tolerance value, press the
key to save. After
saving, the data set will not be lost after shutdown.
4.2.11 List Scanning Function
Turn on the instrument to enter the interface of measurement display, move the cursor to the
list switch through the left and right direction keys, and enter Interface of List Scanning by means
of switching the up and down switch Keys as shown in Fig.4-9 and 4-10. The List Scanning
Function can carry out circulated scanning over seven groups of frequencies and compare them
with the nominal values to get the comparison results. The scanning mode is divided into stepping
scanning and sequential scanning. Set the frequency and upper and lower limits, and then open the
scan display, you can get the measured value and comparison results. Comparison result "H":
greater than upper limit, "L": less than lower limit, "I": within the range between them.
