2.4 ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits.
Vaisala products are adequately protected against ESD for their intended use. However, it is
possible to damage the product by delivering an electrostatic discharge when touching,
removing or inserting any objects inside the equipment housing.
Avoid touching component contacts or connectors when working with the device.

The probe provides both digital and analog outputs.
• In digital output mode, the probe outputs all the measurement parameters.
• In analog output mode, the probe outputs the readings of two measurement parameters
(one parameter in each analog output channel). These measurement parameters are
chosen at the time of ordering the probe, and you can change them using Insight
software and via Modbus. The probe is also compatible with Vaisala Indigo transmitters,
which provide the option of three analog output channels.
