9.2 Changing the energy unit
The energy unit can be changed. In order to do so, follow the example in paragraph 9.1, page 13,
but instead of reading 3-06, reading 3-07 is to be used.
If you change the energy unit setting in Setup loop, you must be aware that the change can
influence the most significant digits of the display. If for instance you change from GJ with 2
decimals to GJ with 3 decimals, the most significant digit disappears. The same applies if you
change from kWh without decimals to kWh with 1 decimal. And conversely, the least significant
digit disappears if e.g. you change from kWh with 1 decimal to kWh without decimals. See
examples below:
Example 1
GJ with 2 decimals (B=2)
This is an example of how the energy reading E1
can appear – counted in GJ.
Example 2
GJ with 3 decimals (B=6)
Here the most significant digit has disappeared
compared to example 1. In return you receive a
higher resolution.
Example 3
kWh without decimals (B=3)
This is an example of how energy reading E1
can appear – counted in kWh.
Example 4
kWh with 1 decimal (B=7)
Here the most significant digit has disappeared
compared to example 3. In return you receive a
higher resolution.
Example 5
MWh with 3 decimals (B=4)
In principle, this is the same resolution as in
example 3, but energy is now counted in MWh.
