8. Troubleshooting

8.1 Analog output error notification

If the device is unable to measure due to an error, the analog output is set to an error level. The
default error level is 0 V, or another value predefined by the customer when ordering the
device.

You can change the analog output error level using the

AERR

command.

‣

Set analog output error indication level (page 50)

8.2 Solving typical problems

You can check the error message via the serial interface by using the

ERRS

command. If you

are unable to remove the errors, contact Vaisala. For contact information, see

Technical

support (page 95)

Table 14 Troubleshooting table

Problem or message

Likely causes and solutions

Measurement not working. Any of the following
errors active:

• T meas error
• RH meas error

Sensor(s) damaged or missing. Open the filter
and check.

Check the supply voltage of the probe.

Check the output mode of the probe using serial
line.

Humidity measurement appears to be wrong.

Check for condensation on the probe and
sensor.

Use the

command to check the currently

applied calibration correction.

Calibrate and adjust the probe (HMP110).

Calibrate the probe and change the sensor if
necessary (HMP60).
