5.3 Power Line Frequency Manual Setting
71
5
For proper electrical noise suppression, the instrument needs to be set to match the power line fre-
quency.
With the default setting (AUTO), the instrument attempts to automatically detect the line frequency,
but manual setting is also available.
Unless the line frequency is set correctly, measurement values may be unstable.
An error message appears if line noise is high enough to prevent correct frequency detection
(ERR:041 (p. 197)). In that case, set the instrument's line frequency manually.
When the [AUTO] setting is selected, the line frequency is automatically set to 50 or 60 Hz when the instru-
ment is turned on or reset.
However, automatic detection is not available when the line frequency changes after turning power on or
resetting.
If the actual line frequency deviates from 50 or 60 Hz, it is set to one of the closest frequencies.
Examples: If the actual line frequency is 50.8 Hz, select the 50 Hz setting.
If the actual line frequency is 59.3 Hz, select the 60 Hz setting.
