Table 4-8
Parameter assign: select target energy parameter for PO convert output. Two ports of PO
can be set corresponding output parameters.
Pulse divider setting: That is the energy value multiplied by a number to output a pulse.
The setting range is an integer from 1 to 9999, unit is 0.1kWh. For example, set the
divider value to 100, that is each cumulative 100 × 0.1kWh = 10kWh output a pulse.
Pulse width time: That is each pulse high level time. The setting range is 0 ~ 5000, the
unit time is 1mS. When set to 0, the pulse duty cycle is 50%.
Note: The maximum pulse output frequency is 40Hz. If it is test pulse output , it

output 1600 pulses per 1kWh.
4.9 Data logging function
In order to facilitate users to understand the history of the meter, the meter provides
data logging function. Record a set of data at regular intervals. Meter internal 4MB of data
storage space for recording data. The meter has a real-time clock and each data log has a
time stamp.
