How do I interpret the error code in the measurement data string of my EOM-O2-FOM / EOM-tO2-FOM / EOM-pH-PHB50 / EOM-CO2-FOM?
The numeric error value in the measurement data string is based on this formula:
2 Bit number = value (see data string output in table below)
Example 1:
E00000001 = 1 = 20 = Bit 0 -> No Pt100 temperature sensor connected
If several errors occur at the same time, the numeric error values are added together.
Example 2:
E00002080 = 2048 + 32 = 211 + 25 = Bit 11 + Bit 5 -> Temperature too high, and photo diode saturated
| Bit | Error | Description | Data String Output |
|---|---|---|---|
| 0 | No Pt100 | No Pt100 connected to the device, or Pt100 not correctly connected | E00000001 |
| 1 | No Sensor | No sensor is connected. (Amplitude < 1000) | E00000002 |
| 2 | Signal amplitude too low | Signal amplitude < 3000 | E00000004 |
| 3 | reserved | - | - |
| 4 | Reference amplitude out of range | Contact service team | E00000016 |
| 5 | Photo diode saturated | Warning: Ambient light or signal strength too high (Measurement is still functioning correctly!) | E00000032 |
| 6 | Reference overflow | Reference strength too high. Contact service team | E00000064 |
| 7 | Signal overflow | Signal strength too high. Decrease signal current | E00000128 |
| 8 | reserved | - | - |
| 9 | reserved | - | - |
| 10 | reserved | - | - |
| 11 | Temperature too high | The max. allowed temperature is reached (see command "ltop") | E00002048 |
| 12 | reserved | - | - |
| 13 | Pulse Counter overflow | The pulse counter has reached the pulse counter overflow limit | E00008192 |
| 14 - 19 | reserved | - | - |
| 20 | Selftest error | Selftest error occurred (see Tab. 10 in Communication Protocol) | E01048576 |
