Receive data in the following format
• Voltage measurement:
<model name>,VOLT,<site number 1>,<site number 2>,<voltage>,<voltage
unit>,<DC±/AC/--><CRLF>
If the voltage is less than 2 V, “--” is returned for <DC±/AC/-->.
Example MY600,VOLT,00,00,100,V,AC<CRLF>
If the voltage is less than 2 V, “--” is returned for <DC±/AC/-->.
• Insulation resistance measurement:
<model name>,<range>,<site number 1>,<site number 2>,<insulation
resistance>,<insulation resistance unit>,<elapsed time>,<1-minute value>,<1-minute
value unit>,<DAR value>,<PI value>,<comparator><CRLF>
Example MY600,1000V,00,00,100.0,MΩ,00:10,----,--,----,----,PASS<CRLF>
* The available six range are 50V, 100V, 125V, 250V, 500V, 1000V.
• Low-resistance measurement
<model name>,CONT,<site number 1>,<site number 2>,<resistance>,<resistance
unit>
Example MY600,CONT,00,00,100.0,Ω<CRLF>
End continuous data transmission: B2
Ends the continuous retrieval of measurement data.

Data format
• Voltage measurement:
<model name>,<data number>,<save data>,<save time>,<range>,<site number
1>,<site number 2>,<voltage>,<voltage unit>,<DC±/AC/-->
Example MY600,0000,2018/03/13,10:33:45,VOLT,00,00,100.0,V,AC
• Insulation resistance measurement:
<model name>,<data number>,<save date>,<save time>,<range>,<site number
1>,<site number 2>,<insulation resistance>,<insulation resistance unit>,<elapsed
time>,<1-minute value>,<1-minute value unit>,<DAR value>,<PI value>

,MΩ,--,----,----
* The available six range are 50V, 100V, 125V, 250V, 500V, 1000V.
• Low-resistance measurement
<model name>,<data number>,<save date>,<save time>,<range>,<site number
1>,<site number 2>,<resistance>,<resistance unit>
Example MY600,0000,2018/03/13,10:33:45,CONT,100.0,Ω
Checksum (CSUM)
The checksum is the value of the last byte obtained by adding each byte from TYPE to
the last DATA or number byte in each command format.
Because the transmission/reception format of 10, 11, B1, B2 and the transmission format
of BN are fixed, their checksums are also fixed.
