The Hioki CM4141 and CM4142 AC Clamp Meters are rated for use with currents up to 2,000 A. These new current sensors feature a compact, sturdy jaw design for easy application around existing wiring, robust enough to push and pull wiring. The CM4141 and CM4142 deliver accurate results even when measuring ac current waveforms that […]
Digital caliper, Pt 1: Background and predecessors
Use of electronics and capacitive-based position sensing have transformed the caliper, a fundamental and essential instrument of precision linear-dimension measurement. Making precise measurements across small distances of up to several inches or tens of centimeters is an obvious and fundamental requirement of modern metrology, research, and mass production. But how can that be done accurately, […]
T&M gear supports PCI Express 5.0 physical-layer testing
The new Teledyne LeCroy QPHY-PCIE5-TX-RX physical-layer software option for LabMaster 10Zi-A series oscilloscopes provides: Automated receiver-test calibration for jitter-tolerance testing at the full 32 GT/sec PCIe 5.0 rate. While existing solutions can take up to a full day to calibrate before even starting the test, the Teledyne LeCroy calibration will be completed in a fraction […]
Flicker spectrometer quantifies light flicker, gauges CIE photometric/radiometric parameter
The GL Spectis 1.0 Touch Flicker Spectrometer is an upgraded version of the handheld Spectis 1.0 Touch Spectral Light Meter. This device can now measure the increasingly important parameter of light flicker in addition to the extensive range of standard photometric and colorimetric values already available. The Spectis 1.0 Touch Flicker Spectrometer is now equipped […]

Multi-function recorder maps ACSI TCP/IP messages to MMS and GOOSE formats
A recorder with IEC61850-8-1, Edition 2, capabilities supports the exchange of time-critical and non-time-critical data through local-area networks (TCP/IP) by mapping ACSI to MMS (Manufacturing Message Specification) and GOOSE (Generic Object-Oriented Substation Event). The TR-3000 multi-function recorder now supports such capabilities such as subscription to GOOSE messages from multiple IEDs (intelligent electronic devices) and the […]
Testing Cat 5e unshielded twisted pair cable and Ethernet connections
Cat 5e (enhanced) cable is widely used in local area networks (LANs), telephone and video. It works well in applications that call for unshielded twisted pair (UTP) and telephone zone wiring in a star configuration. Two telephone lines can be run and two extra pairs are available for future use. Using modular RJ-45 connectors, a […]
DMM incorporates IR camera for accurate thermal fault investigations
The HT Mercury Digital Multimeter is a true RMS DMM capable of conducting diode tests and measuring ac/dc voltage up to 1000 V, ac/dc current up to 10 A as well as resistance, continuity, frequency, capacitance and temperature with a K-type probe. The built-in infrared camera with 80×80-pixel resolution can obtain simultaneous readings of thermal […]
