, Ls-D, Ls-Q and Ls-Rs will be displayed.
d) Press Ls-Q to select the Ls-Q function.
e) Move the cursor to
FREQ
, the current frequency is 1.0000kHz.
f) Press [5][.][5], +5.5 will be displayed in the prompt information zone at
the bottom of the screen. The available units Hz, kHz and MHz will be
displayed in the soft key zone. Press kHz, the frequency will be changed
as 5.5000kHz.
g) Move the cursor to
LEVEL
, the current displayed level will be 1.000V.
h) Press [1][.][5], +1.5 will be displayed in the prompt information zone at
the bottom of the screen. The available units mV, V,
μ
A, mA and A will be
displayed in the soft key zone. Press [ENTER], the level will be changed as
1.5V.
i)
Press [SETUP] to enter into the <MEAS SETUP> page.
j) Move the cursor to R
int
zone, 100
Ω
, 50
Ω
, 30
Ω
and 10
Ω
will be displayed
in the soft key zone.
k) Press 100
Ω
to select 100
Ω
as the signal internal impedance.
3) Connect the test fixture (TH26005) to the test terminals of
STB8827
A.
4) Execute correction (To avoid the influence of stray impedance on
measurement accuracy, Open/ Short correction must be operated) (refer to
5.1.2 “Point-frequency correction”)
5) Mount the tested inductance to the test fixture.
6) Execute test operation.
Press [MEAS] to enter into the <MEAS DISP> page. The instrument can test
continuously and the test result will be displayed in upper case character in the
center of the page.
7) If the test result is obviously incorrect, please check the following items.
a) Check the tested inductance is in good connection with the test fixture or not.
b) Check the test fixture is in good connection with the test terminals of the
instrument or not.
c) Redo the open/short correction.
NOTE:
When the sweep open/short correction is used, the point-frequency
correction function should be set as OFF. Refer to Correction operation in this
chapter.
