Detection of a Cooling Fan Malfunction
2-16
Up to seven sets of setup information can be stored in the internal non-volatile memory.
You can also recall the stored setup information and change the settings.
The TA220 comes standard with GP-IB and Ethernet interfaces. You can output the
jitter or jitter ratio of the selected measurement function to a PC or control the TA220
from an external controller.
The setup information is stored using a lithium battery. When the power switch is turned
ON, the TA220 starts measurement using the settings that existed immediately before
the power switch was turned OFF. If the setup information can no longer be stored due
to a dead lithium battery, the TA220 is reset to the factory default settings.
The following two methods are available for initializing setup information on the instrument.
• Initialization to factory default settings
• Initialization of all setup information except the following.
Network related set up information
Setup information stored to the internal memory
Digital display (green) brightness setting
You can change the brightness of Display 2.
You can disable the front panel key operation.
You can adjust the zero position of the needle.
If you are in doubt as to whether the instrument has malfunctioned, you can run a self
test before contacting a YOKOGAWA dealer. You can check things such as the keys,
rotary knob, indicator, meter, and boards.
Using the internal calibration signal, the offset voltage of the input amplifier and the
conversion coefficient of the time-voltage converter can be calibrated.
The firmware version (ROM version) of the TA220 can be displayed.
The condition of the cooling fan is monitored at all times. If the fan stops, error code 906
is shown on the display. If this occurs, immediately turn OFF the power. If you continue
to use the instrument, a warning is given approximately every ten seconds by displaying
the error code until the cooling fan recovers.
