3.5 Basic Operations

Spot SHORT correction value is given with a numeric value or read
The spot SHORT correction value at current measurement frequency can be given with a
numeric value or it can be read.
After specifying the format of spot SHORT correction value, input or display the spot
SHORT correction value. First, press the
_
SHIFT
_
+ [SHORT] keys to display the SHORT
correction menu, and select FRMT with a numeric key.
FRMT: The format setting menu for the spot SHORT correction value is as shown below.
Format:Ls-Rs Current setting
0)Rs-X 1)Ls-Rs Options
Rs Residual resistance (unit: ) Rs X Rs Ls
X Residual reactance (unit: )
Ls Residual inductance (unit: H)
Select the format with a numeric key.
If a setting is made or the EXIT operation is performed, one-previous menu comes back.
Next, select Entry with the SHORT correction menu.
Entry: The spot SHORT correction input menu is as shown below.
Co-SHORT= Rs:+123.456m X :+123.456m Current value
±(0.0000p to 999999M) Z<900 1.0000kHz Range of settable values
Spot SHORT correction frequency
Following the set format of spot SHORT correction value, the spot SHORT correction
value is displayed. The above screen shows an example of FRMT Rs-X. The frequency
displayed at the lower right of screen is the one at the time when the spot SHORT
correction value was measured or set, and it is not current measurement frequency.
Initially, the cursor exists on the previous value, and when the previous value is input and
entered with the
_
ENTR
_
key, the cursor moves to the next value, indicating that the next
value can be input.
The cursor can be moved between previous and next by pressing the
_
BS
_
| [PREV] or
_
EXP
_
| [NEXT] key.
In either previous or next, if a value is set, the measurement frequency at that time is
recorded as the spot correction frequency.
Perform the EXIT operation to return to one-previous menu.
If the spot SHORT correction value is set, the SHORT correction is disabled. Set the
SHORT correction to ON (enabled) when the set spot SHORT correction value is used.
Though the warning message will be displayed for the input of correction value of
impedance ≧900, it is set as it is as the spot SHORT correction value.
If both previous and next values are zero, it is equivalent to the setting that the spot
SHORT correction is disabled.
