7.3 Power Line Frequency Manual Setting
129
7
With the default setting (AUTO), the instrument attempts to automatically detect the line fre-
quency, but manual setting is also available.
• Unless the line frequency is set correctly, measured values may be unstable.
An error message appears if line noise is high enough to prevent correct frequency
detection (ERR:097 (p. 296)). 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 instrument is turned on or reset.
However, automatic detection is not available when the line frequency changes after turn-
ing power on or resetting.
If the actual line frequency deviates from 50 or 60 Hz, select the closest frequency.
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.
