2. GENERAL DESCRIPTION

2.1. INTRODUCTION

VEGA 76 represents a new approach to the world of electrical measurements. Computer assisted instruments like this permit an easy and fast analysis of a huge quantity of data.

2.2. FUNCTIONS

The instrument can:
• display in real time the electrical parameters of single phase and three-phase systems (with and without neutral wire)
• perform a harmonic analysis of voltages and currents
• perform a direct energy measurement (without storing data).
• memorize (by pressing SAVE) the sampled values of the parameters present at the
instrument’s input by generating a "Smp" record inside the memory. It’s possible to analyze memorized data ONLY by transferring them to a PC.
• record simultaneously (by pressing START after a proper setting): RMS values of voltages, currents, corresponding harmonics, active, reactive and apparent powers, power factors and cosϕ, active, reactive and apparent energies, voltage anomalies (voltage sags and surges) with 10ms resolution. It’s possible to analyze recorded data ONLY by transferring them to a PC.
Please note the difference between memorize and record. These terms will be used repeatedly in this manual. Please focus on their definitions and distinctions.

3. PREPARING THE INSTRUMENT

3.1. PRELIMINARY CHECK

This instrument was checked both mechanically and electrically prior to shipment. All possible cares and precautions were taken to let you receive the instrument in perfect conditions. Notwithstanding we suggest you to check it rapidly (eventual damages may have occurred during transport – if so please contact the local distributor from whom you bought the item). Make sure that all standard accessories mentioned in paragraph 13.3 are included. Should you have to return back the instrument for any reason please follow the instructions mentioned in paragraph 17.

3.2. POWER SUPPLY

The instrument can be powered by batteries (refer to paragraph 13.1.11 for details on model, no. and battery life) and by an external power supply (refer to paragraph 13.3.1 for details on the model) supplied with the instrument as a standard accessory. When batteries are low, a low battery indication is displayed. To replace/insert batteries follow the instructions indicated in paragraph 12.2.
For recordings use ALWAYS the external power supply (although the instrument allows the operator to perform a recording using internal batteries).
The instrument applies sophisticated algorithms to prolong the battery life. Particularly:
• it automatically switches off the backlight after 5 seconds.
• If the instrument is displaying in real time (and the external power supply is not
connected), after about 5 minutes from the last pressure on keys or selector rotation the instrument automatically turns off ("AUTOPOWER OFF" procedure).
• If the instrument is recording or is measuring energy (and the external power supply is not connected), after about 5 minutes from the last pressure on keys or selector rotation the instrument starts a special procedure to save batteries ("ECONOMY MODE"): the instrument keeps recording but the display is turned off.

3.3. CALIBRATION

The instrument complies with the technical specifications contained in this manual and such compliance is guaranteed for 1 year. Annual recalibration is recommended.

3.4. STORAGE

After a period of storage in extreme environmental conditions exceeding the limits mentioned in paragraph 13.2 let the instrument resume normal measuring conditions before using it.
