The calibration point can be set in

on
<CORRECTION>
and then
the open correction frequencies can be set in
FREQ
. Move the cursor to
FREQ
and then use the
MEAS OPEN
soft key to execute open correction on
selected frequency.
Operation steps of open correction function
1) Move the cursor to OPEN, the following soft keys will be displayed:
ON
OFF
MEAS OPEN
DCR OPEN
2) Connect test fixture to test terminal. The fixture is open and not connecting to
any DUT.
3) Press
MEAS OPEN,
STB8827
will test the open admittance (capacitance
and
inductance) under 48 frequencies. It will take about 75 seconds to finish the
open full-frequency correction. In the process of correction, the following soft
key will be displayed:
ABORT
This soft key can be used to terminate the current open correction operation
and reserve the formal open correction data.
4) Press
DCR OPEN
,
STB8827
will test the open-circuit resistance under the
DC resistance function.
5) Press
ON
to turn on the function of open-circuit correction, then
STB8827
will perform open-circuit correction calculation in the later testing process. IF
FREQ is set as OFF, the open-circuit correction data of the current frequency
will be calculated by imbedding algorithm. When FREQ is set as ON, the value
of the current test frequency will be that of FREQ, in this case, the open
correction data of FREQ will be used to the calculation of open correction.
6) Press
OFF
to turn off the open correction function. In later measurement, no
open correction calculation will be taken.
