Procedure of the OPEN/SHORT calibration
This section explanations how to perform the OPEN/SHORT calibration
for a measurement using the directly connectable measuring terminals,
and one for a measurement using the clipping leads "CL-700". (Perform
the OPEN/SHORT calibration according to each procedure.)
[Measurement using the directly connectable measuring terminals]
1. Press the
CAL
button for 2 seconds.
The display shows
[OPEn]
.
2. Press the CAL button again.
The meter shows a countdown on the
display while it performs the OPEN
calibration. It takes 30 seconds to complete.
After the countdown is complete, the display should show [PASS].
4-11 OPEN/SHORT Calibration
The OPEN/SHORT calibration before measurement reduces the parasitic
effect of the test fixture to get better accuracy especially for high/low
impedance measurement. (For the calibration principle, see 6-3.)
3. Insert the bundled shorting plate to the
directly connectable measuring terminals.
4. Press the
CAL
button again.
The display shows
[Srt]
.
5. Press the
CAL
button again.
The meter shows a countdown on the display
while it performs the SHORT calibration. It
takes 30 seconds to complete.
After the countdown is complete,
the display should show
[PASS]
.
If the display shows
[FAIL]
, this procedure has to be performed
again.
6. Press the
CAL
button once again to exit the OPEN/SHORT
calibration mode.
