| Revision history |
+------------------+

Firmware 1.4
------------
- (change) Changing the detection mechanism OUT OF RANGE when no sensor is detected.


Firmware 1.3
------------
- (additional feature) Adding the devices compatibility with the E3N current sensor, coupled with the appropriate adapter.
- (correction) The counting of energy is not arrested in case of "out of range".

Note : this firmware is compatible with hardware versions 0.3 and 1.3.

Firmware 1.2
------------
- (correction) The sign of the reactive values is now correctly handled in 3PHI mode with harmonics.
- (correction) The Rogowski-current-channel gain is set to 1 in Inrush mode (formerly set to 0).
- (correction) Energy counters are now all positive (absolute values).

Note : this firmware is compatible with hardware versions 0.3 and 1.3.

Firmware 1.1
------------
- (additional feature) Energy counting with 8 independent counters (10 pages have been added in "power" mode).
- (additional feature) The DC value of the current is now displayed (in calibration mode) in "current harmonic" mode.
- (correction) An error test for "VAR-with-harmonics" calculation has been added.
- (correction) The "Tangent-Phi" error conditions have been corrected.
- (correction) The "Wave.AFrms" value is now never forced to zero (in order to avoid a frequency calculation instability).
- (change) Frequency error calculation propagation is now deeper.

Note : this firmware is compatible with hardware versions 0.3 and 1.3.

Firmware 1.0
------------
Initial revision.

Note : this firmware is compatible with hardware versions 0.3 and 1.3.
