JZF-9 is a battery powered PD calibrator for direct coupling of the generated PD signal to the test object acc. to the related standards IEC 270 Pulse outputs ranges are0. 5pC, 5pC, 50pC , 500pC. The pulse rise time is < 0. 1us, pulse width < 100ns. A double impulse generator with time lag of 0 – 200us monitors the superposition characteristics and resolution capability of the detector.

The calibrator has a visual indication of the battery status.. The pulse phase angle can be shifted 0 – 360° in relation to the synchronization voltage.
