Display Resolution during Integration
The display resolution for integrated values is 100000 counts. When the integrated
value reaches 100000 counts, the decimal point shifts automatically. For example, if
0.00001 mWh is added to 9.99999 mWh, the display shows “10.0000 mWh. ”
Display Function of Integrator Values
By selecting the display function, you can display the polarity of the integrator values.

*1 When the Wh function is selected, pressing the FUNCTION key once or twice will result in
Wh
±
. Pressing the FUNCTION key once will result in displaying the positive watt hour value,
whereas pressing the FUNCTION key twice will result in displaying the negative watt hour
value. In case of the negative watt hour value, “–” will appear in front of the value.
*2 When the Ah function is selected, pressing the FUNCTION key once or twice will result in
Ah
±
. Pressing the FUNCTION key once will result in displaying the positive ampere hour
value, whereas pressing the FUNCTION key twice will result in displaying the negative
ampere hour value. In case of the negative ampere hour value, “–” will appear in front of the
value.
Note
•
When negative integrated values are displayed, the maximum display reading will become –
99999 MWh/MAh because of the added minus character.
•
When the measurement mode is RMS/VMEAN and the current input drops below 0.5% of the
rated range, the ampere hour value will become zero (0).
•
During integration is in progress (until being reset), operation of other functions are restricted.
