3.5.6.7 OPEN Correction
Executing the OPEN correction can make the admittance zero when the measurement
terminals are opened. For the OPEN correction value, a numeric value can be given, besides
measurement by opening the measurement terminals.
With the measurement terminals open, press the
_ SHIFT _ + [OPEN]
keys to display the
OPEN correction menu, and select Measure, so that the admittance when the measurement
terminals are opened can be corrected to zero.
To set directly the OPEN correction value at current measurement frequency, first select
FRMT to specify the format, and then select Entry to set a correction value, and finally
select ON.
The operation of OPEN correction is executed with the OPEN correction menu.
_ SHIFT _ + [ OPEN ]
Press the
_ SHIFT _ + [OPEN]
keys to display the OPEN correction menu.

OFF Disables the OPEN correction and returns to the measurement screen.
OPEN correction value is held internally.
ON Enables the OPEN correction and returns to the measurement screen.
Measure Measures the OPEN correction value.
Upon completion, enables the OPEN correction and returns to the
measurement screen.
SPOT Displays the spot correction menu.
When the spot correction is enabled, correction value is measured with
current frequency only.
LowFREQ Displays the lower limit frequency setting menu for zero correction.
This can prohibit the correction with low frequencies requiring long
measurement time.
FRMT Displays the format setting menu for spot OPEN correction value.
Entry Displays the spot OPEN correction value input menu.
Perform the EXIT operation to return to the measurement screen.
