The above number of output bytes is indicated as follows:
Measured data:
2 x channel number x n byte (n: number of data items per channel)
Computed data:
4 x channel number x n byte (n: number of data items per channel)
Invalid data are output as follows:
Plus over data
Minus over data
Measurement range setting is SKIP
Abnormal data
No data
Power failure
7FFFH (7FFF7FFFH for computed data)
8001H (80018001H for computed data)
8002H (80028002H for computed data)
8004H (80048004H for computed data)
8005H (80058005H for computed data)
7F7FH (7F7F7F7FH for computed data)
Note
• The output data are all in hexadecimal format.
• Measured data can be output with either the most significant byte or least significant byte following the order of output
bytes with the BO command.
• If the RAM disk is faulty, the character string “# ERROR ON DATA MEMORY” will be output.
• If there are no appropriate files, the character string “# FILE NAME ERROR” will be output.
• One set of power failure information data are written when the power recovers from the power failure regardless of
writing period.
