Kalibratoren für die Messung von Funkstörspannung
Power Diagnostix bietet drei verschiedene Modelle von Kalibratoren für RIV-Messungen an: CAL3A, CAL3B und CAL3D. Sie entsprechen entweder NEMA 107-1987 oder CISPR 18-2.

A pushbutton allows toggling between continuous mode (Cont.) and burst mode (Burst), the latter is indicated by a blinking '+' sign. During the burst mode the calibration signal is turned on for about 8 ms each cycle (20 ms at 50 Hz version).
All calibrators of the CAL3 series offer the charge range of 10 µV to 10 mV. The amplitude can be set in following steps: 0 µV, 20 µV, 50 µV, 100 µV, 200 µV, 500 µV, 1 mV, 2 mV, 5 mV, 10 mV.
A rotary switch on the left side of the calibrator is used to select the signal frequency. The top position '0' selects 600 kHz for the CAL3A. It is increased in steps of 50 kHz up to 1350 kHz. The standard frequency of 1 MHz is selected at lowest position '8'. The CAL3B and CAL3D offer a range of 400 kHz to 1900 kHz in steps of 100 kHz.
Fully Traceable Calibration
 |
Power Diagnostix delivers the calibrators of the CAL3 series with a fully traceable factory calibration.
To ensure a reliable PD measurement, all calibrators shall be calibrated annually; the calibrator is re-adjusted, if necessary, and outfitted with a new battery.
Die Standardkalibratoren der CAL3-Serie von Power Diagnostics sind in der folgenden Tabelle mit ihren Wertebereichen und Hauptmerkmalen aufgelistet.
