About the 123-industrial-box
The Fluke 123 Industrial ScopeMeter is a compact handheld instrument from Fluke's original 120 Series. It puts a two-input 20 MHz digital oscilloscope, a dual-input 5,000-count true-rms multimeter and a TrendPlot recorder in one battery-powered case, for troubleshooting machinery, instrumentation, control and power systems.
Connect-and-View triggering locks onto unknown signals automatically, so motor drive and control waveforms appear without setting amplitude, time base or trigger by hand. The shielded STL120 test leads handle scope, resistance, continuity, diode and capacitance measurements, and the inputs are rated 600 V CAT III.
The instrument connects to a PC or printer through its optical port and an optically isolated RS-232 or USB adapter, for use with FlukeView ScopeMeter software. Fluke's 123/S kit included that adapter, FlukeView software and a hard carrying case.
The Fluke 123 has been discontinued; Fluke's current model in this place is the 123B of the 120B Series.
Frequently asked questions
Is the Fluke 123 still available new?
No. It has been replaced by the Fluke 123B (120B Series).
What came in Fluke's 123/S kit?
According to Fluke's manual, the /S kit added an optically isolated RS-232/USB adapter cable, FlukeView ScopeMeter software and a hard carrying case to the basic kit (test tool, battery pack, charger, shielded test leads, clips and banana-to-BNC adapter).
Can I use a 10:1 probe with it?
Yes. With the VP40 10:1 probe the input impedance is 5 MOhm // 15.5 pF and the full 20 MHz bandwidth is kept; the probe was standard with the 124 and optional for the 123.
