Maximum Reading of the Display and Units
Maximum reading
• Integrated value: 99999 (999999 only when the unit is MWh or MAh), –99999 when
displaying negative polarity
• Elapsed integration time: 10000
• Units: Wh (power integration: watt hour value), Ah(current integration: ampere hour
value)
• Prefix: m, k, M
Selecting the Display Function
The following selections are available.
• Wh: displays both the positive and negative watt hour values
• Wh±: displays the positive watt hour value
• Ah: displays the total ampere hour values
• Ah±: displays the total ampere hour values or the positive ampere hour value
• : the average active power during integration is displayed, if the function is
specified in the computation settings (see section 4.12).
For more details, refer to page 6-3.
Selecting the Input Element
• 1/2/3: Displays the measurement values of element 1/2/3
• Σ: Displays the total integrated values of the elements installed. The method of
computation depends on the wiring method. The computation method changes to
Wh or Ah for the active power W (see page 5-2).
When the display function TIME is selected on display A, there is no element function
available on display A. Pressing the ELEMENT key on display A will result in an error
code.
Update Hold Function
• Although the held values will not be updated, the integration continues inside the
instrument. Because the UPDATE LED blinks each time the internal data is
updated, it will continue to blink. When hold is being cancelled, the integration
results (values and time) corresponding to the point of cancellation, will be
displayed.
• For details regarding the relation with the START/STOP key, refer to the following
