Optionally available for the Handyscope HS5 are SureConnect connection test
and resistance measurement. SureConnect connection test tells you immediately
whether your test probe or clip actually makes electrical contact or not. No more
doubt whether your probe doesn't make contact or there really is no signal. This
is useful when surfaces are oxidized and your probe cannot get a good electrical
contact. Simply activate the SureConnect and you know whether there is con-
tact or not. Also when back probing connectors in confined places, SureConnect
immediately shows whether the probes make contact or not.
Models of the Handyscope HS5 with SureConnect come with resistance measure-
ment on all channels. Resistances up to 2 MOhm can be measured directly. Re-
sistance can be shown in meter displays and can also be plotted versus time in a
graph, creating an Ohm scope.
With the accompanying software the Handyscope HS5 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.

Sampling

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