0..1 – number of binary input which generates a pulse
2.hrs – if the type Energy
0..7 – 2.value of multiple
if the type Pulse
0 – measure time between pulses
1 – measure performance
Description of the calculation of energy:
DC energy(consumption)
Assigned Type=Energy, 1.hr=(0..7), 2.hrs=(0..7)
Because Ether4 has no clock circuit, it is based on crystal frequency of processor (its accuracy
indicates the accuracy of the calculation of energy). About every 1,6s (exactly 3*2^26/(125*10^6) )
timer overflow occurs and at this time is calculated energy.
< Energy > = <Energy> + <1.hr> * <2.hr> / 2235.174
This value is roughly every minute saved in EEPROM (set minute, because memory has a limited
number of entries).
To view the energy is used calculation
<Value> = <Energy> * <Constant>
This allows display energy in Wh (Constant = 1.0), or in kWh (Constant = 0.001)
Consumption of connected meter with SO output
Assigned: Type=Energy, 1.hr=8, 2.hr=(0..1)
Note: because the binary inputs are connected as follows
Connected meter must “master“ level voltage 3,3V. We tested measurement the consumption with
electricity meter Maneler 9901.
Consumption is calculated every 1,6s as follows
< Consumption> = < Consumption > + <Number of pulses>
and the displayed value is
< Consumption > = < Consumption > * <Constant>
where the constant is determined by the type of meter.
