a)press [SYSTEM]
，
JK2817N is displayed to < System Settings > page.
b)Move cursor to unqualified beep area. At present, this area is displayed as HIGH LONG.
4
．
Install test fixture (JK26005) to the test end of JK2817N.
5
．
Perform zeroing operation ,to prevent stray impedance from affecting measurement accuracy,
an open/short circuit correction is required (see Chapter 5.1.1 "Sweep Frequency Zero
Clearance").
6
．
Insert the measured capacitance onto the test fixture.
7
．
Perform measurement operations
Press[DISP]
，
Then press the key list to scan, so that JK2817N can be displayed to < list scan
display > page.The instrument continuously scans the test and displays the test and comparison
results on the page, and gives an alarm when the comparison results are H (up) or L (down).
8
．
If the test results are obviously wrong, please:
a)Check whether the tested device is reliably connected with the test fixture.
b)Check whether the test fixture is reliably connected with the test end of the instrument.
c)Re open reliable open circuit / short circuit correction.
Note: When the user is using sweep open/short circuit correction, the point frequency correction
function must be selected as OFF, referring to the "zero-clearing correction operation" in this
chapter.
5.6 Comparator setup instance
JK2817N provides a more complete comparator function to facilitate the measurement and
identification of production line components and incoming and outgoing inspection.The standard
configuration of the HANDER interface makes it suitable for automatic sorting measurement
systems. The concept and operation of the comparator are described in detail in the previous
chapter. Here are two examples of settings.
5.6.1 Capacitor sorting
Capacitance model:0805CG271
Basic requirements: capacity is divided into two stalls, BIN J and BIN K .the capacity is qualified
and the loss is not qualified, file it separately.
Measurement parameters: frequency 100kHz, level 1Vrms, slow, unqualified alarm, external
trigger.
Sorting parameters :BIN J -4.6%
～
+4.8%
，
BIN K-9%
～
+10%
，
loss tg < 0.15%
This example needs to set the following parameters:
