Changing Measurement Parameter Scaling
If your application requires an analog output scaling that diers from the defaults shown in
Table 3 (page 6), you can configure the scaling by connecting the transmitter to Vaisala Insight
PC software (requires Vaisala USB cable 219690).
2.4
Connectivity to Vaisala Insight Software
The transmitter can be connected to Vaisala Insight software using a Vaisala USB cable (order
code 219690). With the Insight software, you can:
• See device information and status.
• See real-time measurement.
• Configure output parameters and scaling.
• Configure serial communication settings.
