3.2 Configuring Settings

• Setting the synchronization source to DC when using AC input will cause display values to fluctuate, pre-
venting accurate measurement. Set the synchronization source to a value other than DC when using AC
input.
• Input for the parameters selected as synchronization sources must be at least 1% of the range.
• When the SYNC lamp (ERROR) is lit up, accurate measurement cannot be performed.
• Even when the SYNC lamp (ERROR) is not lit up, accurate measurement cannot be performed if the syn-
chronization source input signal is in any of the following states:
1.When a signal with a frequency higher than the frequency measurement range (zero-cross filter) is
being input
2.When a measured voltage or current of an AC component of an input signal is less than 1% of each rel-
evant range.
3.When a measured voltage or current of an AC component of an input signal is greater than 150% of
each relevant range.
4.When a signal with a frequency component within the frequency measurement range (zero-cross filter)
other than the measurement signal’s fundamental wave frequency is superposed
Example: When the frequency measurement rage (zero-cross filter) is 500 Hz, if a signal for which
zero-crosses occur at a frequency of less than 500 Hz (a modulation signal, noise, etc.) is
input on top of a 50 Hz input signal
• The synchronization source cannot be changed while integration is being performed or during display hold
or maximum value/ minimum value display hold operation.
