The CRC Checking：
The returned CRC register is as unsigned short int.
The star address and the field of the data are transmitted, the returned CRC
registered with the low and high byte has been swapped.
/*CRC Generation Function with ‘C’ language*/
/* Msg:*message to calculate CRC upon*/
/* usDatalen: number of bytes in message*/
unsigned int CRC16(char *Msg,unsigned char usDatalen)
{
unsigned char uchCRCHi=0xFF；/*CRC high byte*/
unsigned char uchCRCLo=0xFF； /*CRC low byte*/
unsigned char uIndex；
while(usDatalen--)/*pass through message buffer*/
{
uIndex=uchCRCHi^*Msg++；/*calculate the CRC*/
uchCRCHi=uchCRCLO^auchCRCHi[uIndex]；
uchCRCLo=auchCRClo[uIndex]；
}
}
return (uchCRCHi<<8|uchCRCLo)；
6.8 The CRC Calculation：
The CRC is calculated on all bytes of a message from the address to the
last data byte inclusively. The CRC field is the result of a CRC calculation
performed on the message contents. The meter will not reply to
commands with a CRC in error and the host should re-transmit the
command after a preset time-out period. If the host receives a string with
a CRC in error, the transaction should be retransmitted. A message is
represented for being from the address field to the data field.
The calculation is performed as follows：
1.Load a CRC register with 0xFFFF
2.Exclusive-OR the first 8 bytes of the message with the low-order of the
CRC register. Put the result in the CRC register
3.Shift the CRC register one bit to the right, filling the MSB with a zero,
and comparing the bit shifted out
4. Repeat step 3 if the SLSB=0; Exclusive-OR the CRC register with the
value A001 Hex, and put the result in the CRC register if the SLSB=1
5. Repeat steps 3 and 4 until the 8 bits have been performed and tested
6. Repeat steps 2 to 5 until all bytes have been processed
7. Swap a message with the low and high order bytes after calculating the
CRC register

Hour Scale：The values will be re-calculated if the ratio of primary to secondary has
been changed.
Value=Received Data * 10 ^ (Hour Scale - 3 )。
Example：The address 132H is represented as 12345678，and the Hour Scale is 5, thus the
hour reading is calculated as follows.
SWH = 12345678 * 10 ^ ( 5 - 3 ) = 12345678 * 10 ^ 2
= 12345678 * 100 = 1234567800。
= 1234567800 WH = 1234567.800 KWH = 1234.5678 MWH。
If Hour scale = 5，put 5 in the given formula then get (5-3 = 2)，and the unit for energy register
is programmed as WH, so (2-3 = -1) is represented as 0.1KWH，or (2-6 = -4) as 0.0001
MWH.

6.9.5 Unit and Decimal Point󶁪
The received integer data as the primary values. And the set-up in unit and decimal point must be
completed after receiving data.
* *The received values will be correct after the set-up in CT & PT ratio has completed. **
Others：
PF：Fixed decimal point position at 3 digits.
H z：Fixed decimal point position at 2 digits.
* * If the Unit set to 6 represents M, and the Dot set to 3 represents 000, and then it can also be
regarded as Unit=K and Dot=0. The other collocation can be analogized as well.**
E xamples：11.4KV/114V、100/5A. 3P4W.
PT Ratio：100times, CT Ratio：20 times.
V Unit：3. V Dot：2. A Unit：0. A Dot：2. Power Unit：6. Power Dot：3.
If the fed volt is at 11.4kV, the fed amp is at 65A, the fed power factor is at 0.95, and the fed
frequency is at 60, and therefore, the values in VA derives from 11.4KVx65Ax3=2223000=2.223MVA
=2223kVA. And the values in W derives from VAxPF=223000x0.95=2111850.
The RS485 receives the following values：
V：1140. A：6500. HZ：6000.
Detailed explanations for the above values are below：
V：11.4KV, Unit in K (V unit=3), Decimal point at 2 digits (V Dot=2)
A：65.00A (A Unit=0), Decimal point at 2 digits (A Dot=2)
V A： 2.223 MVA or 2223 KVA
Unit in M (decimal point at 3 digits) or Unit in K (without decimal point)
W ：2.111MW or 2111KW. Please refer to the description of VA
Unit in K (Energy Unit=3), without decimal point (Energy Dot=0)
P F：0.950. Decimal point at 3 digits
Hz：60.00Hz. Decimal point at 2 digits
Notice：The Unsigned Int is non-symbol, but the Signed Int is a value with positive/negative.
The values will be measured correctly if the corresponsive signals are matched.
Furthermore, some parameter units (kW, Var, Pf) display positive or negative.
Examples：PF=0.95：RS 485 values：950；PF= -0.95：RS 485 values：-(65536-64586)= -950
