Error message | Interpretation and action |
---|---|
Difference too big |
The adjustment cannot be made if the difference between the measured concentration and the given value is more than 20 % of the maximum value of the probe's measuring range. This message can be caused by a considerable high drifting error of the probe. Contact Vaisala (see Technical support). |
Value too high |
The reference concentration can be at the highest 110 % of the maximum value of the probe's measuring range. Make the adjustment using a lower reference gas concentration. |
Lower value too high |
The lower reference gas concentration must be less than 20 % of the maximum value of the probe's measuring range. Make the adjustment using a lower reference gas concentration. |
Higher value too high |
The higher reference gas concentration can be at the highest 110 % of the maximum value of the probe's measuring range. Make the adjustment using a lower reference gas concentration. |
Values too close |
The difference between the reference concentrations must be at minimum 20 % of the maximum value of the probe's measuring range. Make the adjustment using correct reference gas concentrations (see above). |
CO2 value too high |
The measured CO2 concentration is too high for the measurement range of the probe, or the calibration is not properly done. The screen goes blank. Move the probe to a location with less CO2 or recalibrate. |
Probe error: Reboot |
This error can occur when changing the probe while power is on. Switch off power and connect the probe properly, then switch on power. |
Probe error |
This error can occur when changing the probe while power is on. Switch off power and check that the probe is connected properly: unscrew the probe fastener. Insert the probe to the handle as deep as possible. Turn the probe inside the handle until you feel that a step in the probe connector snaps into the groove of the handle connector and locks the probe. Tighten the probe fastener. Switch on power. |
Adapter error | Switch off power and check that the probe is connected properly (see the instructions for handling a Probe error message. In case of continuous error, contact Vaisala. See Technical support. |
