Do not use the instrument on networks of which the voltage or category exceeds those mentioned.
Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.
Do not use the instrument without its battery.
Before each use, check the condition of the insulation on the leads, housing, and accessories.Any item of which the insulation
is deteriorated (even partially) must be set aside for repair or scrapping.
Before using your instrument, check that it is perfectly dry. If it is wet, it must be thoroughly dried before it can be connected
or used.
Use only the leads and accessories supplied. The use of leads (or accessories) of a lower voltage or category limits the voltage
or category of the combined instrument and leads (or accessories) to that of the leads (or accessories).
Use personal protection equipment systematically.
Keep your hands away from the terminals of the instrument.

2. DESCRIPTION OF THE INSTRUMENT
2.1. FUNCTIONS
The CA 8345 (Qualistar 2) is a portable three-phase power quality analyser with built-in rechargeable battery. It is in compliance
with the standard governing the methods of measurement of power quality, IEC 61000-4-30, class A.
The CA 8345 is used:
to measure the RMS values, powers, and disturbances of power distribution networks.
to take a snapshot of the main characteristics of a three-phase network.

The measurement uncertainty of the instrument is better than 0.1% for voltage measurements and 1% for current measurements.
The instrument provides a large choice of current sensors, for measurements from a few milliamperes up to several kiloamperes.
The instrument is compact and impact-resistant.
The ergonomics and simplicity of its user interface make it a pleasure to use. The CA8345 has a large colour touch screen graphic

3.3.2.1. GPS MODE
The GPS mode is necessary to guarantee that your instrument is classA (per IEC 61000-4-30). The instrument must be exposed
at least once to the GPS satellites, so that the receiver can recover the date and time. Correct synchronisation may take up to 15
minutes. Accuracy is then maintained, even if the satellites are no longer accessible, in the following situations:
