4.6 Alarm Set-up
This sets the upper and lower limit alarm. The upper and lower limit set value mark "
the bar graph. From the display items, 4 element can be set.
In the operation mode, press

Note 1: Even if it is a measurement item not selected by the display pattern, it is possible to select it.
Note 2: The alarm of W, var, and PF is judged from the total RMS value.
Note 3: The upper alarm of A and DA is judged from the phase of 1, 2, 3 and N.
The lower alarm of A and DA is judged from the phase of 1, 2 and 3. (N is excluded.)
Note 4: The alarm of the total distortion ratio is judged from the phase of 1, 2 and 3. (N is excluded.)

Note: An upper and lower limit alarm index by the bar graph is displayed in the step of about 5% though the digital
value can be set in the above-mentioned step on A, DA, V, W and var. However, the alarm is generated with
the accuracy of the digital value.
DA: current demand
V alarm value is set for value of primary voltage (direct voltage).
A, DA, W and var is set for value of rated scale.
