ATTENTION!

Measuring directly on the line voltage can be very dangerous.

The outside of the BNC connectors at the Handyscope HS4 are connected

with the ground of the computer. Use a good isolation transformer or a dif-

ferential probe when measuring at the line voltage or at grounded power

supplies! A short-circuit current will ﬂow if the ground of the Handyscope HS4

is connected to a positive voltage. This short-circuit current can damage both

the Handyscope HS4 and the computer.

Revision 2.27, February 2020

Despite the care taken for the compilation of this user man-

ual, TiePie engineering can not be held responsible for any

damage resulting from errors that may appear in this man-

ual.

Safety 1

When working with electricity, no instrument can guarantee complete safety.

It is the responsibility of the person who works with the instrument to op-

erate it in a safe way. Maximum security is achieved by selecting the proper

instruments and following safe working procedures. Safe working tips are

given below:

•Always work according (local) regulations.

•Work on installations with voltages higher than 25 VAC or 60 VDC should only

be performed by qualiﬁed personnel.

•Avoid working alone.

•Observe all indications on the Handyscope HS4 before connecting any wiring

•Check the probes/test leads for damages. Do not use them if they are dam-

aged

•Take care when measuring at voltages higher than 25 VAC or 60 VDC.

•Do not operate the equipment in an explosive atmosphere or in the pres-

ence of ﬂammable gases or fumes.

•Do not use the equipment if it does not operate properly. Have the equip-

ment inspected by qualiﬁed service personal. If necessary, return the equip-

ment to TiePie engineering for service and repair to ensure that safety fea-

tures are maintained.

•Measuring directly on the line voltage can be very dangerous. The out-

side of the BNC connectors at the Handyscope HS4 are connected with

the ground of the computer. Use a good isolation transformer or a diﬀer-

ential probe when measuring at the line voltage or at grounded power

supplies! A short-circuit current will ﬂow if the ground of the Handyscope

HS4 is connected to a positive voltage. This short-circuit current can damage

both the Handyscope HS4 and the computer.

Environmental considerations

This section provides information about the environmental impact of the Handy-

scope HS4.

End-of-life handling

Production of the Handyscope HS4 required the extraction and use of

natural resources. The equipment may contain substances that could

be harmful to the environment or human health if improperly handled

at the Handyscope HS4’s end of life.

In order to avoid release of such substances into the environment and to reduce

the use of natural resources, recycle the Handyscope HS4 in an appropriate sys-

tem that will ensure that most of the materials are reused or recycled appropri-

ately.

The shown symbol indicates that the Handyscope HS4 complies with the European

Union’s requirements according to Directive 2002/96/EC on waste electrical and

electronic equipment (WEEE).

Introduction 3

Before using the Handyscope HS4 ﬁrst read chapter 1about safety.

Many technicians investigate electrical signals. Though the measurement may not

be electrical, the physical variable is often converted to an electrical signal, with

a special transducer. Common transducers are accelerometers, pressure probes,

current clamps and temperature probes. The advantages of converting the phys-

ical parameters to electrical signals are large, since many instruments for examin-

ing electrical signals are available.

The Handyscope HS4 is a portable four channel measuring instrument. The Handy-

scope HS4 is available in several models with diﬀerent maximum sampling rates.

The native resolution is 12 bits, but user selectable resolutions of 14 and 16 bits

are available too, with reduced maximum sampling rate:

resolution Model 50 Model 25 Model 10 Model 5

12 bit 50 MSa/s 25 MSa/s 10 MSa/s 5 MSa/s

14 bit 3.125 MSa/s 3.125 MSa/s 3.125 MSa/s 3.125 MSa/s

16 bit 195 kSa/s 195 kSa/s 195 kSa/s 195 kSa/s

Table 3.1: Maximum sampling rates

The Handyscope HS4 supports high speed continuous streaming measurements.

The maximum streaming rates are:

resolution Model 50 Model 25 Model 10 Model 5

12 bit 500 kSa/s 250 kSa/s 100 kSa/s 50 kSa/s

14 bit 480 kSa/s 250 kSa/s 99 kSa/s 50 kSa/s

16 bit 195 kSa/s 195 kSa/s 97 kSa/s 48 kSa/s

Table 3.2: Maximum streaming rates

With the accompanying software the Handyscope HS4 can be used as an oscil-

loscope, 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.

3.1 Sampling

When sampling the input signal, samples are taken at ﬁxed intervals. At these in-

tervals, the size of the input signal is converted to a number. The accuracy of this

number depends on the resolution of the instrument. The higher the resolution,

Introduction 5

the smaller the voltage steps in which the input range of the instrument is divided.

The acquired numbers can be used for various purposes, e.g. to create a graph.

Figure 3.1: Sampling

The sine wave in ﬁgure 3.1 is sampled at the dot positions. By connecting the

adjacent samples, the original signal can be reconstructed from the samples. You

can see the result in ﬁgure 3.2.

Figure 3.2: ”connecting” the samples

3.2 Sampling rate

The rate at which the samples are taken is called the sampling rate, the number

of samples per second. A higher sampling rate corresponds to a shorter interval

between the samples. As is visible in ﬁgure 3.3, with a higher sampling rate, the

original signal can be reconstructed much better from the measured samples.
