MEAS SHORT
Perform short correction for full frequency and DCR
DCR SHORT
Perform DCR short correction only.
Step 4
Press [MEAS SHORT] soft key, a dialog message display “Short-circuit the test terminals”.
Step 5
Short-circuit the test fixture with a shorting piece, or clamp the test cable together, do not
place any tested parts, and do not touch anything.
Step 6
After pressing [OK], the instrument starts to perform correction.
When correcting, there will be a progress bar prompt at the bottom of the page, and the
“Trig'd” indicator will flash.
After the correction is completed, the progress bar disappears.
During correction, users can cancel the correction at any time by pressing the [Abort] button.
5.2.3
Frequency spot 1, 2, 3 Correction [SPOT 1] [SPOT 2] [SPOT]
Correction based on specified frequency spots involves performing open/short/load
correction at user-specified frequency points. There are 3 frequency spots you can specify.
To specify frequency spots and perform correction
Step 1
Press the [Setup] key, then press [CORRECTION] to enter <CORRECTION> page.
Step 2
Use the cursor key to select [SPOT 1] [SPOT 2] [SPOT3] field
Step 3
Use the soft keys to select or directly enter the frequency value, frequency that is not within
the instrument's characteristic frequency will be approximated to the typical frequency.
If the current frequency point is is turned off before:
Soft key
Function
ON
Enable this frequency correction point
CURRECT FREQ
Specify the frequency being used as the current frequency spot value
If the current frequency point is is turned on before:
Soft key
Function
OFF
Disable this frequency correction point
CURRECT FREQ
Specify the frequency being used as the current frequency point value
MEAS OPEN
Individually perform open correction for this set frequency
MEAS SHORT
Individually perform short correction for this set frequency
Step 4
Press [MEAS OPEN] soft key to perform an open-circuit correction
Or, Press [MEAS SHORT] to perform a short-circuit correction.

<BIN TABLE> Page
Press [Setup] key and press [COMP setup] soft key to open <BIN setup> page.
This page allows you to configure the AT381x's built-in comparator.
AT381x's built-in comparator can sort DUTs into a maximum 11 levels (BIN1 through BIN9,
AUX and OUT) using up to nine sets of primary parameter limits along with one set of
secondary parameter limits.
In addition, the comparator has a bin count function that counts up to 999,999 DUTs.
To take full advantage of the comparator, AT381x was equipped a handler interface for use in
conjunction with the comparator, all of these bins signal can output to yours PLC via the
handler interface.
In the <COMP Setup> page, you can configure each of the following controls with the cursor
