Communication data which is opened to users includes primary grid float
type data and secondary grid int/long type data. Please read the instruction
for data storage address and format in communication address table carefully,
and make sure to transmit data according to relative format.
It is suggested to download testing software MODSCAN32 for checking
MODBUS-RTU communication protocol from our homepage. This software
adopts standard MODBUS-RTU protocol which can display data in the
formats such as integer, float and hexidecimal, so that you can compare the
data with measured data displayed on the meter directly.
Communication indication sign
There is a communication indication sign in the display interface of meters.
If a meter receives communication data during communication test process,
this communication sign will flash.
6.2 Measured data is not correct
First make sure that the meter has been input right voltage. The
multimeter is used for measuring voltage. Electric quantity displayed on the
meter is the value of primary grid; it may lead to wrong electric quantity
display if the ratio of voltage transformer does not conform to that of
transformer in-service. The defaulted voltage range is not allowed to be
modified after delivery. Connection network is available to be modified
according to actual connection on spot, but the connection mode set in
programming shall correspond with the actual connection method, otherwise
it may lead to wrong display.
6.3 Meter does not work
Ensure proper auxiliary supply
（
AC/DC80-270V
）
is linked to the auxiliary
supply terminal. As the meter may be damaged by auxiliary supply voltage
which is beyond rated range and can not recovery. Use multi-meter to
measure the voltage of auxiliary supply, if the meter does not display when
the voltage is proper, please electrify again.
