1.0 Introduction
Congratulations! You have purchased a Personal Computer (PC) USB with analog and systems performance that
rivals the best Digital Multimeters on the market. These all-in-one Digital Multimeters (DMM’s) are easy to setup
and use, have sophisticated analog and digital circuitry to provide very repeatable and super accurate measurements,
and are protected to handle any unexpected situations your measurement environment may encounter. To get years
of reliable service from these DMM’s, please take a few moments and review this manual before installing and
using this precision instrument.
This manual describes the SMU2060 and SMU2064 DMMs.
1.1 Safety Considerations
Safety Considerations
The SMU2060 series of USB Digital Multimeters (DMMs) are capable of measuring up to 330 VDC or
330 VAC across the Volt HI and LO terminals, and can also measure common mode signals that "float"
the DMM above EARTH ground by up to 330 VDC or 250 VAC. When making common mode
measurements, the majority of the circuits inside the DMM are at the common mode voltage.
These
voltages can be lethal.
The DMM enclosure must not be tempered or disassembled for any reason. Doing so will result in
performance degradation and will present a safety risk.
Improper handeling of these products can
result in lethal voltages that may effect the computer this product is connected to.
Warning
No probes or any other wiring should be connected to the DMMs during installation or removal of
the USB to the DMM or to the Computer. Not doing so may apply lethal measurement voltages to
your computer and USB cable, causing electrocution and/or damage to your computer and/or your
DMM.
To avoid shock hazard, connect the USB cable only to a computer that has its power connector
connected to a power receptacle with an earth safety ground.
When making any measurements above 50 VDC or 40 VAC, only use Safety Test Leads.
Examples
of these are the Signametrics Basic Test Leads and Deluxe Test Leads, offered as an accessory with the
Signametrics DMM’s.
1.2 Minimum Requirements
These USB DMMs are precision plug-in modules that are compatible with personal computers (PCs). It requires as
a minimum a Pentiums computer. A mouse or a compatible pointing device must be installed when controlling the
DMM from the Windows Control Panel provided with this product. These DMMs comes with a Windows' DLL,
for operation with Windows' Version 95/98/Me/2000/XP and Milenium.
1.3 Feature Set

The base unit, the SMU2060, has traditional 7-1/2 digit features and it can be used as a general purpose DMM,
where accuracy and speed are important. The High Workload Multi Function SMU2064 adds timing, capacitance,
inductance, sourcing , leakage and more speed. With its specialized measurements, it can replace several costly
instruments, shrinking the size and cost of a test system. It is possible to deploy several SMU2060s, SMU2064s and
