Foxborough, MA — Compliant with IEC 61243-3 Edition 2, AEMC’s new C.A 771 and C.A 773 VAT voltage testers can be used to work on any 1,000V CAT IV installation. They are rated IP65 and meet Köppen-Geiger type-S extended climatic class re- quirements for indoor and outdoor use, including extreme conditions.
ZYGO Intros High-Res Laser Interferometer
Middlefield, CT —ZYGO Corporation has introduced its Verifire™ HDX laser interferometer system with ultra-high spatial resolution and ad- vanced imaging for measuring the surface form and transmitted wave- front of high-performance optical components and systems. At the core of the Verifire HDX
is a new optical design, which deliv- ers improved instrument transfer function (ITF) and ultra-high spatial resolution for superior characteriza-
To meet the requirements of cer-
tain countries, these testers are avail- able in two versions, equipped with IP2X test probes or without. The C.A 771 and C.A 773 have a redundant safety system in the event of power supply failure. Their ELV LED flashes when the
voltage exceeds 50 VAC/120 VDC. Safety is ensured when testing GFCI and residual current device (RCD) tripping by means of a double control system. Both hands are needed to press the two buttons simultaneously. The integrated autotest checks the electrical circuits, power supply,

displays, and the condition of the measurement leads. Phase rotation measurement is simple and quick with a two-wire microprocessor system. Audible and visual continuity
testing is provided in compliance with Appendix B of the IEC 61243-3 standard. The tester can also detect stray voltages and offers unipolar
phase identification. Contact: AEMC Instruments,

tion of mid-spatial frequency (MSF) characteristics and high-slope sur- face form errors, with high precision and confidence. Loaded with standard features,
including a low-noise, high-speed, 11.6 MP sensor and vibration-resist- ant acquisition technologies, the Ver- ifire HDX system sets a benchmark for optical metrology, MSF charac- terization and process control for critical applications. The Verifire HDX system can be
configured for a wide range of appli- cations, with available apertures from 25 to 800 mm (1 to 31.5 in.), horizontal and vertical mounting configurations and a complete line of reference optics and accessories. ZYGO Corporation is a unit of AMETEK Ultra Precision Technolo-
