frequency correction takes about 75 seconds and in this process, the
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, TH2827 will test the short resistance under DC resistance
function.
5) Press ON to validate the short correction function. TH2827 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 TH2827
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
