Using Scanner Interface
Using Multi-correction Function
Selecting definition method of the LOAD correction standard
You can select how to define the LOAD correction standard value (LOAD
correction reference value): either defining a value for each channel or defining
a common value for all channels. If you select the channel-by-channel
definition, the value is set up as the reference value for the channel selected
when you enter the reference value. If you select defining a common value for
all channels, the value is stored as the value for all channels regardless of the
channel selected when setting up the value. Refer to “Structure of data for
LOAD correction” on page 104.
The procedure to select the definition method of the LOAD correction standard
value (LOAD correction reference value) is given below.
Step 1. Press [Meas Setup].
Step 2. Press the CORRECTION softkey.
Step 3. Use the cursor keys to select the LOAD REF field.
Step 4. Use the following softkeys:
Measuring OPEN/SHORT/LOAD correction data
The procedure to measure OPEN/SHORT/LOAD correction data for
multi-correction is the same as that for the usual correction data, except that
you need to select a proper channel before the measurement. For more
information, refer to “Obtaining Correction Data” on page 98.
When you measure the OPEN/SHORT/LOAD correction data with the
multi-correction function ON, the measured value is stored as the correction
data for the channel selected at the time of measurement. For information on
the structure of the correction data, refer to “Structure of data for OPEN
correction” on page 98, “Structure of data for SHORT correction” on
page 100, and “Structure of data for LOAD correction” on page 104.
Checking OPEN/SHORT/LOAD correction data
The procedure to check OPEN/SHORT/LOAD correction data for
multi-correction is the same as that for the usual correction data, except that
you need to select a proper channel before the measurement. For more
information, refer to “Checking Displaying/Setting Up Correction Data” on
page 110.
Softkey Function
SINGLE Defines a single LOAD correction standard value commonly applied to all
channels.
MULTI Defines a LOAD correction standard value for each channel.
