Power ON Operation
Self-test starts automatically when the power switch is turned ON. If the test completes
successfully, the GS820 is set according to the setup file selected in section 11.3,
“Selecting the Settings Applied at Power ON.” Check that the GS820 has started
normally before you use it.
Note
If you are turning the power switch ON after turning it OFF, allow at least 5 s before turning it
ON.
When the Power-on Operation Does Not Finish Normally
Turn off the power switch, and check the following items.
• Check that the power cord is securely connected.
• Check that the voltage supplied from the power outlet is correct. See section 3.3.
• You can initialize the settings of the GS820. See section 11.3.
If the GS820 still fails to power up when the power switch is turned ON after checking
these items, it is probably a malfunction. Contact your nearest YOKOGAWA dealer for
repairs.
To Make Accurate Measurements
In the installation location indicated in section 3.2, allow the instrument to warm up for at
least 60 minutes after the power switch is turned ON. Turn the output off during warm-up.
After the warm-up time elapses, turn the output on.
