SparkFun Support and Front Desk will be closed on Thursday 11/14 from 1-2:30pm for a company event. Please plan to pick up your orders before or after this timeframe.
It seems like everything plugs in to your computer these days, and this digital multimeter is no exception. This auto-ranging multimeter will test AC and DC voltage and current as well as capacitance, resistance, frequency and even temperature. It features a large, easily readable display for use in the field as well as the ability to connect to your computer for data logging, processing and analysis. It has all of the basic functions that you expect from a good digital multimeter including continuity check (with buzzer), diode test and data hold. Data logging and analysis software is included on a mini-CD and you can also download it below.
Note: The included CD contains all versions of the software. The version that has been tested to work with this unit is version 3.0. You can also just use the download link in the Documents Tab.
Note: This meter does have a USB interface, but it's not clearly RS232. The meter needs the proprietary software to function and you cannot simply read the data directly without a driver and the software.
The included CD has the software to use with this multimeter. The install should also have the drivers. When connected via USB the device should enumerate as "Silicon Labs CP210x USB to UART bridge (COM##)".
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

After 30 years in my career as an Electronics CET, I have twisted many Knobs, POT's and function switches sometimes ending up in the wrong range, wrong measurement function, flopping my DMM on it's side or collapsing it. The push button and auto range is a welcome relief. The RS232 commo is outstanding for logging data and also setting up a trouble shooting routine for equipment that is serviced continuously. This routine may be used by laymen in order to relieve the work load of the Supervising Technician. You can find great innovations, education and great products at Sparkfun! Thanks Guys

This appears to actually be a Victor 70C multimeter, potentially with customized firmware. The included RS232 interface software is windows only but neither it nor open-source alternatives like sigrok-cli actually worked for me (Win7/64bit), though the DMM did register as a serial port.
For someone digging further into this, the the protocol is potentially documented at https://sigrok.org/wiki/Victor_protocol
Not much else to say here except that this device is very excellent. It lives up to the expectation of a medium cost hobby meter and the autoranging feature is very stable. Definitely a tool to recommend.
This meter was affordable and digital. I looked at the yellow ones but could not justify the expense for a hobby. This has beeper for continuity checks and digital for other measurements. Works well for me.
Looks like they took the Victor86C USB protocol and changed 1 or 2 things.
0 - jodenxunickxia is still the magic value for subtracting bytes 1 - I think the 'scrambler' step may have been reversed or else I'm reading the disassembly wrong. 2 - the bytes in the 14-byte packet are now bit-reversed.
