* In the case of Auto Update Rate cannot use the Integration function and store the measurement data.
Data update rate × 2 or less
(The time it takes to reach the accuracy of the final value when the displayed value changed from 0
to 100% or 100 to 0% of the rated range)
The indicator illuminates when the input signal meets the conditions for auto range switching.
Overrange "- - - oL -" is displayed for the following conditions.
Crest factor 3, 6
• When the measured value exceeds 140% of the rated range
* WT310EH:40 A range
When the measured value exceeds 110% of the rated range
Crest factor 6A
• When the measured value exceeds two times of the above setting.
Holds the displayed value.
Updates the displayed value once each time the SINGLE key is pressed during Hold.
Holds the maximum displayed value of U, I, P, S, Q, U±pk, I±pk, and P±pk.
