Craftsman Professional 82324 Datalogging Meter Info and Software Page
time to put on your hard hat and venture into the mine yet again for
some retro technology archaeology. (Wow, try saying that a few times
Sad as it will be when it happens,
Sears(-Roebuck*) seems likely to be history before too long. I'm
bringing you this page because the Craftsman 82324 multimeter is
already history as far as Sears is concerned. They no longer provide
any support whatsoever for this meter and as I've got a bit of a thing
about companies abandoning whatever support materials they had for a
product, I tossed up this web page with some useful tidbits. One has to
do what they can to keep something from disappearing into the dustbin
If you've got a Craftsman 82324 meter
and need some information about it, or the data logging software, you
are in the right place.
I'm not sure when the 82324 meter was
first marketed or for how long. Sears gives their address on the manual
as being in Hoffman Estates, so it was clearly made and sold after
they'd left the Sears (Willis) Tower.
A (pretty badly, and ridiculously huge) scanned manual is here. (Warning: five megabytes!) At least it's readable. I'll scan my own sometime.
Speaking of software, despite the big
deal that's made on the meter's packaging about being "designed for
Windows 95", the software itself is a 16-bit Visual Basic 3.0 program.
It'll run perfectly well on Windows 3.1x, Windows 9x, and even in the
Win16 on Win32 (WoW) subsystem that exists in all 32-bit versions of
Windows NT, 2000, XP, Vista, 7, 8/8.1 and 10. 64-bit versions of
Windows never had the WoW subsystem (or its NTVDM underpinnings) and
therefore cannot run 16-bit Windows programs such as this one.
The claim is made that a 386 or better processor is required, but I'd
not be surprised to find that it ran just fine on a 286 system (if you
had one and wanted to use it with this software). I could, and might,
put this to a test sometime!
The software was originally distributed on a single high density floppy diskette, available for download here as a disk image. If you don't have a floppy drive (and a depressingly large number of people don't, or only think they have one in the form of a USB attached model), a ZIP archive of the diskette's contents are also available for download, right here.
Setup refused to run on one of my laptops (with, to be completely fair, an extremely elderly installation of Windows 98). If this happens to you, here's a ZIP archive
of the program fully expanded and ready to use. The installer doesn't
do much of anything special, although it might squirt out a
vbrun300.dll (and maybe threed.vbx) into your Windows directory.
Likewise, you can always just expand the files yourself, with
Microsoft's command line expand.exe utility.
This meter was manufactured for Sears by Metex and as a result, uses their common 600 baud, 14-byte ASCII signaling protocol.
The software indicates having been developed by
AGA Associates in 1998 (!) and supports only the 82324 multimeter. It
supports both color and monochrome (!) screens. Whoever AGA Associates
is (or was), it's not clear if they are around any longer. Metex
manufactured many meters with different brand names on them. It's very
likely that the Sigrok
software has support for this meter, although I've yet to personally
test it since I'm quite happy with the Sears-supplied software. The
Sears software probably works equally well with any of the identical
meters made by Metex.
The software features data logging,
"scope" like functionality, the ability to review captured data and
despite its aged design, seems to work extremely well. Decent help
screens are available, and with the software having been produced
domestically, they are written in proper, understandable English.
Communications are unidirectional. It is not possible to control the meter from the data logging software.
This appears to be nothing more than
an (almost) "straight through" DB-9 serial cable with a male connector
at the meter end and a female connector at the PC/serial port end. A
serial extension or switchbox cable ought to work perfectly well if you
don't have the original.

There is proper isolation hardware
between the meter's logic and the serial port. I have no idea if the
meter will work through a USB to serial adapter, although it probably will so long as said adapter is set up to have the I/O address of a traditional serial port (COM1-COM4).
The Craftsman 82324 meter, outside of
its data logging capability, is a pretty conventional digital
multimeter with autoranging. No manual range selection capability is
provided. You can make relative measurements and hold the current meter
reading. Test ranges include Volts AC (750V maximum), Volts DC (1000V
maximum), ohms up to 40MΩ, audible continuity (tone sounds with 50Ω or
lower resistance), diode test (1.5mA at 1kΩ), DC amps and AC amps.
Current test ranges are 4mA, 400mA and a rather surprising 20A. All
current test ranges are fuse protected. Since the fuses are rated for
250 volts only, I would not recommend measuring any current flow on
circuits having higher voltages. An explosion or other serious failure
and injury may be the result!
Although there's some suggestion that a true RMS version of this meter was made, the 82324 I have is not a true RMS meter! It will therefore give incorrect results on AC signals that are not pure sinewaves.
Sears provides the typical figure of
10MΩ input impedance. A low battery indication exists within the
display. There is no backlight. (I can tell you that battery life is
very good. Even after many days of data logging, my meter is still
running on the battery I installed in 2015.) There is no auto power off
Replacement Parts (but good luck actually getting any of these today!)
No, I don't have any of these for sale or otherwise. You can call Sears and try your luck.

A NIST certification was available
under Sears item number 83740. (Yeah, I was pretty surprised as well.)
This involved taking the meter to its place of purchase (or presumably
any Sears store), where it would then be forwarded to a calibration
laboratory. My guess is that this couldn't have been cheap. I also have
to wonder if anyone actually did so!
That's about all I've got. Hopefully
you found it useful. Soon as you've dusted your clothing off, you can
send any questions or commentary to me!

I once read somewhere, probably on Wikipedia, that Alvah Roebuck made
much of his outliving the much more well known Richard Sears, who fell
into ill health not long after founding the company that everyone
simply calls "Sears" today. Last updated 06/22/2018.
