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 Handyprobe HP3 before connecting any wiring
•The Handyprobe HP3 is designed for CAT II measurement category: Maxi-
mum working voltage 600 VRMS or 800 VDC. Do not exceed the rated voltage.
•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.

Environmental considerations
This section provides information about the environmental impact of the Handy-
probe HP3.
Handyprobe HP3 end-of-life handling
Production of the Handyprobe HP3 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 Handyprobe HP3’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 Handyprobe HP3 in an appropriate sys-
tem that will ensure that most of the materials are reused or recycled appropri-
ately.
The symbol shown below indicates that the Handyprobe HP3 complies with the
European Union’s requirements according to Directive 2002/96/EC on waste elec-
trical and electronic equipment (WEEE).
Restriction of Hazardous Substances
The Handyprobe HP3 has been classified as Monitoring and Control equipment,
and is outside the scope of the 2002/95/EC RoHS Directive.

Introduction 3
Before using the Handyprobe HP3 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 Handyprobe HP3 is a single channel, 10 bits measuring instrument with dif-
ferential input with high input range. The Handyprobe HP3 is available in sev-
eral models with different maximum sampling frequencies and different maximum
streaming rates.
HP3-100 HP3-20 HP3-5
Maximum sampling rate 100 MS/s 20 MS/s 5 MS/s
Maximum streaming rate 10 MS/s 2 MS/s 500 kS/s
Table 3.1: Maximum sampling frequencies
The Handyprobe HP3 is available with two memory configurations, these are:
Memory HP3-100 HP3-20 HP3-5
Standard model 16 kS 16 kS 16 kS
Option XM 1 MS 1 MS 1 MS
Table 3.2: Maximum record lengths per channel
With the accompanying software the Handyprobe HP3 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 Differential input
Most oscilloscopes are equipped with standard, single ended inputs, which are
referenced to ground. This means that one side of the input is always connected
to ground and the other side to the point of interest in the circuit under test.
Introduction 5
Figure 3.1: Single ended input
Therefore the voltage that is measured with an oscilloscope with standard, single
ended inputs is always measured between that specific point and ground.
When the voltage is not referenced to ground, connecting a standard single ended
oscilloscope input to the two points would create a short circuit between one of
the points and ground, possibly damaging the circuit and the oscilloscope.
A safe way would be to measure the voltage at one of the two points, in reference
to ground and at the other point, in reference to ground and then calculate the
voltage difference between the two points. On most oscilloscopes this can be
done by connecting one of the channels to one point and another channel to
the other point and then use the math function CH1 - CH2 in the oscilloscope to
display the actual voltage difference.
There are some disadvantages to this method:
•a short circuit to ground can be created when an input is wrongly connected
•to measure one signal, two channels are occupied
•by using two channels, the measurement error is increased, the errors made
on each channel will be combined, resulting in a larger total measurement
error
•The Common Mode Rejection Ratio (CMRR) of this method is relatively low. If
both points have a relative high voltage, but the voltage difference between
the two points is small, the voltage difference can only be measured in a
high input range, resulting in a low resolution
A much better way is to use an oscilloscope with a differential input.
