Note
•
Be careful since measurement data will be lost when initializing. However, measurement
data or setup parameters stored in the internal memory will be kept.
•
If the setup parameters are initialized by a communication command (RC command or
*RST command), parameters related to GPIB and serial communication will not be
initialized.
When Initializing Setup Parameters at Power-On
If the power switch is turned ON while holding down the ENTER key, the WT210/WT230
powers up using initial settings. Keep holding down the ENTER key until the illumination
of all LEDs turn off (step
of the "Opening Message" on page 3-10). All setup
parameters including communication parameters will be initialized as indicated above.
When the setup parameters are initialized, error codes "Err. 60" and "Err. 78" are shown
as messages to indicate the initialization; they do not indicate a malfunction.
