Industrial scopemeter extends capabilities

Published:  08 May, 2007

Fluke has introduced the Fluke 125 Industrial ScopeMeter which offers a number of additional test capabilities compared to other models in the 120 Series. New features include a 'Bus Health Test' for industrial bus networks, harmonics analysis, and power measurements and other functions aimed at troubleshooting motor drives and frequency converters. The new handheld Fluke 125 Industrial ScopeMeter combines a 40MHz, dual-input digital oscilloscope with two 5,000 counts true-rms multimeters, and dual-input paperless recording for intermittent fault finding. With a 600V CAT III safety rating for the meter and accessories and up to 7 hours battery operation, Fluke says it is the ideal handheld oscilloscope for the demanding plant service, maintenance and installation engineer locating problems in machinery, instrumentation, control and power systems.

Compared to the Fluke 124, the Fluke 125 Industrial ScopeMeter offers a new industrial network ‘Bus Health Test" which rigorously checks electrical signal quality on recognised industrial field buses such as  Profibus and Modbus. Also new are the ability to analyse harmonics up to the 33rd over a wide frequency range, particularly useful for non-linear loads; power measurements for single and 3-phase systems over a wide frequency range, e.g. at the output of motor drives and frequency converters; VPWM measurements to indicate the true output voltage of motor drives; high resolution resistance measurement for fault finding in motor windings; and plain text entry to identify stored test data.

Fluke’s Connect-and-View triggering recognises signal patterns and automatically sets up correct triggering. It provides a stable and repeatable display of virtually any signal - including motor drive and control signals. This overcomes problems related to manual trigger setting, which can result in unstable and sometimes incorrect results.

TrendPlot enables the Fluke 125 to act as a ‘paperless recorder’, capturing minimum and maximum peak values and averages over time for up to 16 days. The two inputs can plot any combination of volts, amps, temperature, frequency and phase, with time and date stamps, to help to locate even the most intermittent of faults.
