Setting the Frequency of Power Supply Manually
5.8 Setting the Frequency of Power Supply
Manually
There are three power supply frequency settings: AUTO, 50 Hz, and 60 Hz.
To eliminate any noise, the supply power frequency needs to be set properly.
In the default setting, the power supply frequency is supposed to be identied
automatically (AUTO) when the power is supplied, however, it also can be set
manually.
If the power supply frequency is not set properly, a measured value does not stabilize.
Even in the AUTO setting, if the power supply frequency cannot be detected properly
due to signicant power noise, an error (ERR:097) is displayed when the power is
supplied. Set the frequency according to the power supply.
