frequency correction takes about 75 seconds and in this process, the
34
following soft keys will be displayed.
ABORT
This soft key can be used to cancel the current short correction operation and
reserve the formal open correction data.
4) Press
DCR SHORT
,
STB8827
will test the short resistance under DC resistance
function.
5) Press
ON
to validate the short correction function.
STB8827
will make
short
correction calculation in latter test. If
FREQ
is set as OFF, the short correction
function will calculate the short correction data of the current frequency. If
FREQ
is set as ON and the current frequency is
FREQ
, the short correction
data of
FREQ
will be used in the calculation of the short correction.
6) Press
OFF
to turn off the short correction function. In latter test, no short
correction calculation will be performed.
3.6.3 LOAD
By using transport coefficient between the real test value and the standard
reference value at the preset frequency (
FREQ
), the load correction of
STB8827
can eliminate the test error. It is obvious that open, short,
and load correction can be performed at preset frequencies. The preset
frequencies can be set in the setup zones of
FREQ
. The standard reference
values can be set in the setup zones of
REF A
and
REF B
. The standard test
function must be set in the
FUNC
zone before setting standard reference value.
When the cursor moves to
FREQ
, the
MEAS LOAD
soft key will be displayed.
Press
MEAS LOAD
to perform the load correction test.
Operation steps for setting load correction
According to the following steps, perform open/ short/ load correction test at
preset frequencies.
1) Move the cursor to
FREQ
, the following soft keys will be displayed:
ON
Press this soft key to make the open/short/load correction data be
available.
OFF
Press the soft key to make the open/short/load correction data be
unavailable.
MEAS OPEN
Press this soft key to execute open correction at FREQ.
MEAS SHORT
Press this soft key to execute short correction at FREQ.
MEAS LOAD
Press this soft key to execute the load correction at FREQ.
2) Press the soft key
ON
, the original preset open/short/load correction
