6.6. Pulse outputs
Outputs type: OC (open collector); 27V DC/50mA
Pulse:
Pulse output 1 is configurable: for kWh or kvarh. Value set up kWh/kvarh per 1 pulse:
0,01 = 10 Wh/VArh
0.1 = 100 Wh/VArh
1 = 1 kWh/kVArh
10 = 10 kWh/kVArh
100 = 100 kWh/kVArh
1000 = 1000 kWh/kVArh.
Pulse output 2 is non-configurable
for kWh: 3200 pulse/kWh
Pulse width:
Output 1 - configurable: 200 / 100 / 60 ms
Output 2 - non-configurable
: 200ms
6.7. RS-485 output for Modbus RTU
Baud rate: 2400, 4800, 9600, 19200, 38400 bps
Parity: NONE – default / ODD / EVEN
Stop bits: 1 / 2
Network address: 1÷247

8. Reference conditions of influence quantities
Influence quantities are variables that affect measurement errors to a minor degree.
Accuracy is verified under nominal value (within the specified tolerance) of these conditions.
