correction.
Avoiding work-related mistakes in measuring correction data
To avoid simple mistakes related to work when measuring correction data (for
example, setting up the OPEN state and SHORT state inversely), it is important
to confirm that the measured data has a proper value.
If a measured value is not proper during measurement of the correction data, a
warning message appears on the display. However, the occurrence of a
warning message cannot be detected through GPIB/LAN/USB. Therefore, to
detect erroneous correction data through GPIB/LAN/USB, you need to read
out the correction data after each measurement and then confirm that the
value is appropriate.
Sample program
See Example 9-3 to view an example of recovering the correction data.
When you write correction data, note the following:
• Before writing, recall the settings of the measurement frequency, cable
length, and frequency shift (for 1 MHz) specified when the data was
read.
• For the LOAD correction data, in addition to the above, you also need to
recall the settings of the LOAD correction standard (definition value and
parameter type) specified when the data was read.
• Turn ON the correction function. (Unlike when measuring the correction
data, writing the correction data does not automatically turn this
function ON.)
