Display Resolution during Integration
The display resolution of integrated values is normally 99999 counts (counts up to
999999 only when the unit is MWh or MAh). When the integrated value reaches 100000
counts, the decimal point shifts automatically. For example, if 0.0001 mWh is added to
9.9999 mWh, the display shows “10.000 mWh.”
Display Function of Integrator Values
By selecting the display function, you can display the polarity of the integrator values.
Display function Measurement mode Display contents
Wh RMS, VOLTAGE MEAN, DC both positive and negative watt hour values
Wh

*1
RMS, VOLTAGE MEAN, DC positive watt hour value
Wh
±
*1
RMS, VOLTAGE MEAN, DC negative watt hour value
Ah RMS, VOLTAGE MEAN total ampere hour values
DC both positive and negative ampere hour values
Ah

*2
RMS, VOLTAGE MEAN total ampere hour values (same as Ah)
DC positive ampere hour value

DC negative ampere hour value
*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 minimum display reading will become –
99999 MWh/MAh because of the added minus character.
• During integration is in progress (until being reset), operation of other functions are restricted.
