You can set the language of the error messages displayed on the screen during
operation to English or Japanese.
You can set the language of the menus displayed on the screen to English or Japanese.
The RGB video signal (VGA, Video Graphics Array) can be output to an external monitor.
This allows values and waveforms to be displayed on a large screen.
Zero-level compensation is when the WT500 creates a zero input condition in its internal
circuitry and sets the level at that point to the zero level. Zero-level compensation
must be performed to satisfy the specifications of this instrument (see chapter 14).
Zero level compensation is automatically performed when the measurement range or
input filter is changed. However, when the measurement range and input filter are not
changed over an extended time, the zero level may change due to the changes in the
environment surrounding the instrument. In such cases, you can manually perform
zero-level compensation. There is also a function that automatically performs zero-level
compensation during integration.
When the NULL feature is turned on, the Udc and Idc values (numeric data of the simple
average of the voltage and current) are set as NULL values. The NULL values are
subtracted from the sampled voltage and current values. All measurement functions are
affected by the NULL values.
The key lock can be used to prevent inadvertent operation errors. The shift lock can be
used to reduce the number of times you press SHIFT.
The measurement of two WT500s can be synchronized by making one WT500 the
master and the other WT500 the slave. The master outputs a measurement start signal,
and the slave receives the signal.
You can view information about the WT500, such as the model, firmware version (ROM
version), input element configuration, and installed options.
The WT500 can evaluate its internal memory (RAM) and panel keys to determine if they
are working properly.
