Protocol
The transmission of the measurement data is disabled by default. Pressing the RS232 button lights up the RS232 symbol on the display and starts transmitting data. Data is sent in 15 byte chunks consisting of 13 hex nibbles encoded in ascii, followed by <CR><LF>
| Header 1 | Header 2 |
|---|---|
| Bytes 0-1 | Function code ie. Voltage DC, Resistance, etc. |
| Bytes 2-5 | BCD (Binary coded decimal) encoding of digits shown on the LCD |
| Bytes 6-7 | Bargraph segment value |
| Byte 8 | Range code, used to convert digits to actual value |
| Byte 9 | Current mode ie AC, DC or AC+DC |
| Byte 10 | Peak status ie. Min/Max/Avg |
| Byte 11 | Range settings ie. Auto, Manual |
| Byte 12 | Polarity of meter reading |
