wingless Posted November 27, 2023 Report Share Posted November 27, 2023 Long, long ago I sold my analog oscilloscope. Long ago I sold my digital oscilloscope. There is a planned upcoming project, for which I again need an oscilloscope. This project requires battery portability. My selection for this instrument was a used Fluke ScopeMeter. I selected this Fluke 105B 100MHz ScopeMeter Series II, purchased used off eBay. This was manufactured in 1997 and is in VERY lightly used condition. It even still has the clear screen protection film in place. It appears only the AC/DC charger and the red 'scope probe have been used at all. The seller stated the NiCad battery pack has recently been replaced. This is a full featured combination 100MHz two channel 5GS digital oscilloscope and true RMS digital mulitmeter. When operated as a multimeter, it permits concurrent display of a single oscilloscope channel. The operational power is either the ~4 hour internal NiCad batteries, the external AC/DC power brick adapter or four alkaline C cell batteries in place of the NiCad batteries. Mine does not include the no longer available optional Fluke PM9087 12V automotive adapter cord. The tool holster wraps the instrument, providing shock protection and a nice multipurpose stand. The probe connections are recessed for protection. The stand may either be tall, short, or grab onto a vertical panel, like the top of a standard door. The instrument includes an optically isolated RS-232 cable w/ adapters. So far I've been unable to get the correct FlukeView software, permitting screeen dump and remote control. The cable permits direct printer output w/o having the software. The operational control was not immediately obvious / intuitive to me, being a looong time Tektronix oscilloscope user, so I reluctantly had to crack open the User's Manual. Now everything makes sense. One feature that surprised me on the utility was the dedicated Information button, showing multiple screens for the currently selected function. Here is the User Manual. The instrument has a large / clear / readable display, w/ standard software contrast control and selectable backlighting. The complete probe kits include everything required for normal usage, including grabber or pointy tips and multiple options for grounding. Each group of probe parts includes a nice / appropriate storage bag. There is a very nice / sturdy hinged plastic case w/ pockets and elastic retainers for all the accessories and nice metal closure latches. There is even a (currently unused) spot for a current probe. All in all this looks to be an excellent choice for my current and future measurement requirements.

wingless Posted December 1, 2023 Author Report Share Posted December 1, 2023 Several updates on this Fluke ScopeMeter 105B instrument... The used instrument was received w/ the optically isolated serial communication cable, but not the SW90W FlukeView ScopeMeter software. It was not possible to locate that software anywhere, so I called Fluke. They sent it to me by E-Mail for free, yea! The 1999 software would not install onto my Windows 7 computer, but installed fine onto my older Windows XP computer. My next discovery was that NONE of my computers have a serial interface, so I purchased an inexpensive USB to serial cable. That adapter cable REQUIRES usage of the included CD for proper installation. The FlukeView software works fine w/ the serial interface, for control and for data / image transfer. Even at the maximum 19.2K bit rate it is waaay slow by today's standards, but is functional. It is an acceptable way to get hand held oscilloscope images into the computer for additional usage. The USB to serial cable fits nicely into the existing Fluke zipper cable storage pouch used by the optically isolated serial cable and the two serial cable adapters. A really nice used Fluke 80i-110s AC/DC clamp on current probe was purchased. This is a VERY handy instrument. It is powered by a standard 9V 6LR61 battery. The current probe has a dedicated storage space in the existing case lid. The current probe manual also has a dedicated storage space in the existing case under the hand held oscilloscope. One FlukeView waveform image (top right) shows voltage, current and one of the built-in math functions, of Channel A times Channel B, for in this case, power. There are many other math functions available. There are also calculation and cursor functions, as would be expected in modern digital oscilloscopes.

Eric - TIA Posted December 4, 2023 Report Share Posted December 4, 2023 Very cool. This is something I have to start digging into and learning more. When it comes to these tools and electric, I am so far behind. Quote Link to comment Share on other sites More sharing options...
