3.5 Basic Operations
3-53 ZM2376
Measurement of OPEN correction values
First, place the measurement terminals in open state.
Figure 3-8 Terminal processing at OPEN correction
To measure the OPEN correction values, press the _SHIFT_
+ [OPEN] keys to display the OPEN
correction menu, and select Measure with a numeric key. With the initial setting, it will take about
40s to measure the correction values.
During the measurement of OPEN correction values, the following message is displayed.
OPEN Measurement (>1kΩ)
Running 9)ABORT
The measurement of OPEN correction value can be aborted by pressing the _9_
key. The above
message is also used as the correction value measurement abort menu.
Upon completion of OPEN correction value measurement, the OPEN correction is enabled, and the
following completion message is displayed for a short time, and then the measurement screen comes
back.
Completed Correction ON
However, when measured value ≤1kΩ, the following warning message is displayed.
Warning: Out of range
Same warning message is also displayed when the measurement failed by any reason. Even if this
warning message is displayed, the ZM2376 use the obtained measured values as OPEN correction
values. However, the previous OPEN correction values are held for the frequencies at which the
measurement failed.
This warning will disappear when any key is operated or after several seconds have passed.
Perform the EXIT operation to return to one-previous menu.
