Internal i
mpedance: 100Ω
Operation steps
1)
Turn on the instrument.
2)
Set basic parameters
a)
Press [MEAS] to enter into the <MEAS DISP> page.
b)
Move the cursor to
FUNC
zone, the current item is displayed as Cp-D.
c)
Press the soft key Ls
—…
▼
, Ls-D, Lp-Q, Ls-Rs, DCR and Ls-DCR 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][.][0], +5.0 will be displayed in the prompt information zone at
the upper of the screen. The available units Hz, and kHz will be displayed
in the soft key zone. Press kHz, the frequency will be changed as
5.000kHz.
g)
Move the cursor to
LEVEL
zone, 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, μA, mA and A will be
displayed in the soft key zone. Press [TRG], the level will be changed as
1.5V.
i)
Move the cursor to
RSOU
zone,
30Ω
,
50
Ω
and
10
0Ω
will be displayed in
the soft key zone.
j)
Press
100Ω
to selec
t 100Ω as the
signal internal impedance.
3)
Connect the test fixture (U26005) to the test terminals of JK2830.
4)
Execute correction (To avoid the influence of stray impedance on
measurement accuracy, Open/ Short correction must be operated).
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, shown as below:
