FIGURE 8-16. Lightning Protection Scheme

8.2.7 Validating and Fine-Tuning CRVW3 Settings

Before completing the deployment of your CRVW3, you should confirm that it

is configured to operate in the way you expect. Plan to have a laptop or other

Windows computer running

DevConfig

with you in the field so you can

connect to and configure the device. Be sure to bring the USB cable (pn 27555)

that was included in your CRVW3 shipment. Section

8.1.5

Configuring the

CRVW3

(p. 23)

, discusses the basic configuration of a CRVW3 device. If no

configuration of the CRVW3 for the current sensors has been previously

performed, first follow the steps outlined in that section to configure the

CRVW3.
