Standard model, multi-rate energy statistics, historical electric energy
statistics, single-phase rail smart energy meter.
Measure and monitor electric energy parameters in the distribution system Energy efficiency management system Statistical analysis of internal power consumption and basis for charging statistics Automatic meter reading system for electric energy me asurement Intelligent power distribution management system
Pulse output: KPM31A&B provides active/reactive energy measurement, active
energy pulse output function, adopts the output of the optocoupler open
collector, the method of energy accuracy inspection refers to the national
measurement regulation: the pulse error comparis on method of the standard
meter.
4.5 Prepayment The user needs remote pre stored electric energy. When the pre
stored electric energy is 0, it will prompt the user to purchase electric
energy (automatic power transmission after 10 seconds of power failure). The
instrument defaults to an overdraft limit of 5 degrees, and the user can set
and read the overdraft limit remotely. 4.6 Load control The user can set /
read the load threshold remotely, and view the load threshold locally in the
p-val display item. The default is 65535kW. When the active power is greater
than the load threshold for 30 seconds, the instrument will cut off the power.
After the power is cut off, the power can only be transmitted through the
local interface operation (the “Relay” option of the setting interface). 4.7
Relay control mode The relay control mode is divided into local mode and
remote mode, and the default is remote mode. Local mode: the default
prepayment and load control functions are turned on. The control of the relay
is controlled by the local instrument according to the state of the
electricity meter, and the remote control does not work . Remote mode: the
default prepayment and load control func-tions are turned off, and the relay
is controlled remotely. Note: switch between remote and local modes through

Please make settings before starting measurement. When entering the setting screen, you need to press and hold for 3 seconds to enter the password input interface. The default password is 6666. the password correctly. Long press key to enter the parameter setting interface, and then press key to select the item to be set, after long press key, the first number from left of the set value will start to flash, short press key to select the digit to be modified, short press the key to increase modified bit value. After finish the modification, long press key to confirm. In the setting interface, if there is no operation for 30s, it will return to the measurement display screen, or short press the and keys at the same time to return directly to the
