DEFINING MULTIPLICATION FACTOR
• Hz has a multiplication factor of 100 & not 1000. e.g. If Hz is 48.33, and then it
is sent as 4833.
• For providing resolution, all parameters except PT are multiplied with 100
before transmitting. Thus if the KVA value is 278.99, it is sent out as 27899. PF
has MF of 1000, instead of 100. Thus, a PF value of 0.987 is sent as 987.
• If an attempt is made to read some address other than the valid addresses, the
exception response is sent.
EXPEPTION CODE
In the event that the query from the HOST has no communication error, but there is
some error in specifying the address of registers to be read, the meter returns an
exception message. The format of the exception message will be as under:
Unit Address 0X83 Exception code CRC CRC
Exception Code can have only one value, 02: if the address is not a valid, start
address or host has requested more than 32 bytes of data, this code is returned.
