Introduction

Before using the Handyscope HS4 DIFF first read chapter
about safety.
Many technicians investigate electrical signals. Though the mea-
surement may not be electrical, the physical variable is often con-
verted to an electrical signal, with a special transducer. Common
transducers are accelerometers, pressure probes, current clamps
and temperature probes. The advantages of converting the physical
parameters to electrical signals are large, since many instruments
for examining electrical signals are available.
The Handyscope HS4 DIFF is a portable four channel measuring
instrument with differential inputs. The Handyscope HS4 DIFF
is available in several models with different maximum sampling
frequencies: 5 MS/s, 10 MS/s, 25 MS/s or 50 MS/s. The native
resolution is 12 bits, but user selectable resolutions of 14 and 16
bits are available too, with adjusted maximum sampling frequency:
With the accompanying software the Handyscope HS4 DIFF can be
used as an oscilloscope, a spectrum analyzer, a true RMS voltmeter
or a transient recorder. All instruments measure by sampling the
input signals, digitizing the values, process them, save them and
display them.

which are referenced to ground. This means that one side of the
