Changing Upper/Lower Limits for Alarm Activation and Cancellation
»
During Alarm Generation
Alarm condition: When a measured value exceeds the alarm value setting, the screen begins to flash and the alarm contact closes.
Alarm cancelled: When the alarm is cancelled, the screen stops flashing and the alarm contact opens.
»
Alarm Cancel
The alarm can be reset automatically or manually. The alarm recovery method varies according to the reset method setting.

If the item that caused the alarm is displayed on
the screen, the digital value, unit (A, V, W, var,
PF, HZ, %, DM, THD) and phase (1, 2, 3, N) will
be displayed as shown in the table below. If the
item is not displayed on the screen, the screen will
not flash.

The alarm resets automatically when the measurement value returns to within the upper/lower limit set value.
The alarm setting changes to “on hold” even after the measurement value becomes returns to within the upper/lower limit value setting. Once the
value returns to within the upper/lower limit value set, perform the following alarm recovery operations.
(Note: Alarm recovery operations cannot be carried out from the maximum/minimum value display screen or digital input screen.)
<To select item and cancel alarm>
When the item that caused the alarm is displayed, press the button to deactivate the alarm.
For items with phases such as current and voltage, it is necessary to
press the button for each phase to cancel the alarm.
<To cancel alarms for all items>
To cancel alarms for all items at once (batch), press the button for 2 s when in operating mode.
If an alarm delay time has been set, alarm notification begins only when the measurement value exceeds the upper/lower limit
alarm value for a period longer than the alarm delay time.

Harmonic Display
The harmonic effective value, distortion ratio and content
ratio can be displayed. To do so, first set the harmonic
display (set-up menu: 3.2).
