HIGH BANDWIDTH & HIGH ACCURACY

Conventional PQ Analyzers, even if they are Class A certified, are not sufficient for modern measurement applications. We use the best available components to ensure the highest safety category and also the highest accuracy. NEO instruments offer high bandwidth (up to 1 MHz) and correct the frequency dependent behavior of current & voltage sensors as well as integrated electronics to achieve the best possible measurement results

SENSOR INTEGRATION

All current sensors offered by NEO Messtechnik are industry proven for different applications. We use and improve on the best available sensors in the market.

FREQUENCY DEPENDENT CALIBRATION
The NEO sensor integration calibrates each sensor over a wide frequency bandwidth and corrects frequency dependent phase shift and amplitude damping. This allows for high precision from DC to high-frequency measurements.

MEASUREMENT RANGE DEPENDENT CALIBRATION
In addition, the sensors will calibrated for each measurement range using multiple points. The calibration will typically cover points from 1% to 100% of the nominal measurement range. This will improve the accuracy and precision, especially at low current (e.g., 1% of nominal measurement range).

LEADING IN SAFETY

Overvoltages from power lines down to factories can be higher than normal operating voltages. To avoid any kind of electrical accident, NEO Messtechnik emphasizes the importance of a safe instrument design. For example, the high-voltage inputs of the PQA 8000 instrument (CAT IV 600V) are isolated up to 6kVp while maintaining high precision (0.05%) and high sampling (up to 1MS/s). This is world-leading technology.

1.  SETUP

The instrument has a clear structure that shows schematics with explanations.

2.  MEASURE

During measurements the user can define widgets such as Scopes, Vector Scopes, Harmonic FFTs, Tables, and Recorders.

3.  ANALYSE

Sophisticated functions include PQ Data, Transients, Disturbances, and Alarms.

4.  REPORT

The instrument can automatically generate reports and professional documentation. The user can create reports that include all relevant information (location, comments, company logo, etc) directly on-site or during post processing. PDF reports that are saved on the instrument are always available and can be shared directly via email.

5.  EXPORT

Data can be exported into CSV, XLS, PDF, Comtrade, and PQDiff.

6.  OTHER PROGRAMS

The instrument uses Microsoft Windows© as the operating system. Programs such as Microsoft Excel, Word or Matlab can be added as well as Email messaging services.
