»Changing Upper/Lower Limits for Alarm Activation and Cancellation

When measurement values exceed the upper/lower limit values that have been set, an alarm activates and the screen begins to blink.

The blinking mark on the bar graph indicates the current upper/lower limit value settings.

Press the button to change to the maximum and minimum values

of the display screen. Press it again to return to the current value display screen.

Press the button for 2s to reset the maximum/minimum values of

the measurement items displayed. The maximum/minimum values will

become the current values.

Press the and buttons simultaneously for 2s to reset all

maximum/minimum values. The maximum/minimum values will become the current values.

Items measured can be displayed on the bar graph. By displaying one item by a bar graph and other three items by digital numbers

four elements can be displayed at once.

The or mark indicates that the measurement item is displayed on the bar graph.

• Select bar graph

Press the or button to select the measurement items to be displayed on the bar graph.

Change the unit (M, k, none) or increase the digits in the bottom display for power used/reactive power used/apparent power

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.

Alarm delay Time

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 »Changing the Harmonic Degree Display

The harmonic effective value, distortion ratio and content

ratio can be displayed. To do so, first set the harmonic

display (set-up menu: 3.7).

Press the or button to change the harmonic degree.

Operating Instructions

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 contact input screen.)

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 at once (batch), press the button for 2s when in operating mode.
