# QUALISTAR+ C.A.8336

The C.A. 8336 (Qualistar+) is a three-phase network analyzer with colour graphic display and built-in rechargeable battery.

It plays three roles, and can be used:

- To measure the RMS values, powers, and perturbations of electric distribution networks.
- To deliver a snapshot of the principal characteristics of a three-phase network
- To track the variations of various parameters over time.

The measurement uncertainty of the device is better than 1% (not counting the uncertainties due to the current sensors). The device is also very flexible, with a choice of sensors allowing measurements ranging from a few milliamperes (MN93A) to several kiloamperes (AmpFlex®).

The device is compact and impact resistant.

The ergonomics and simplicity of its interface make using it pleasant.

The C.A 8336 is intended for the technicians and engineers of electrical installation and network inspection and maintenance teams.
