19 Signametrics
3.0 Getting Started
After unpacking the DMM, please inspect for any shipping damage that may have occurred, and report any claims
to your transportation carrier.
The DMM is shipped with the Digital Multimeter module; four floppy disks which contain the various software
panels and drivers plus the calibration data specific for the unit, and this Operator's manual.
3.1 Setting the DMM
The SM2040 series DMMs are PCI plug-and-play devices and do not require any switch settings, or any other
adjustments to the DMM prior to installation.
The SM40CAL.DAT file supplied with your DMM has a unique calibration record for that DMM (See
"Calibration" at the end of this manual.) When using multiple DMMs in the same chassis, the SM40CAL.DAT
file must have a calibration record for each DMM. Append the unique calibration records of each DMM into one
SM40CAL.DAT file using a text editor such as Notepad. The defalut location for the SM40CAL.DAT file is at
the root directory C:\.
3.2 Installing the DMM Module
Warning
To avoid shock hazard, install the DMM only into a personal computer that has its power line connector
connected to an AC receptacle with an Earth Safety ground.
After installation, check to see that no loose wires or ribbon cables infringe upon any of the internal circuits
of the DMM, as this may apply measurement voltages to your computer, causing personal injury and/or
damage to your computer!
Caution: Only install the DMM module with the power turned OFF to the PC!
Use extreme care when plugging the DMM module(s) into a PCI bus slot. If possible, choose an empty slot away
from any high-speed boards (e.g. video cards) or the power supply. Please be patient during the installation
process! The DMM comes with 4 safety-input jacks. Because of their necessary size, they are a tight fit in many
PC chassis. Insert the bracket end of the DMM into your PC first, watching for any interference between the safety
input jacks and your PC chassis. “Sliding” the bracket end of the DMM into the chassis may be helpful. Be
patient! You should only have to install it once!
3.3 Installing the Software
It is recommended that you first plug in the DMM into the PC chassis, than turn on the computer power. The first
time you power up your computer with the DMM installed, your computer will detect the new DMM and prompt
you for a driver. The driver your computer requires is located on Disk 1 (SM2040.INF).
To install the software, run the ‘SETUP’ program provided on the Diks1. This takes care of all installation and
registration requirements of the software. If you are installing the DMM on a computer that had an SM2040 series
install in it, you should first uninstall the old software. Also make sure you backup and remove the old calibration
record (SM40CAL.DAT). For a clean reintallation remove all INF files containing reference to the Signametrics
DMM. Dependig on operating system, these files will be located at Windows\inf, Windows\inf\other or
WINNT\inf. The files will be named Oemx.INF where x is 0,1,2,… and/or SIGNAMETRICSSM2040.INF. If
present, these files will prevent “Found New Hardware” wizard from detecting the new DMM.
