Datasheet

TiePie engineering claims to be the first oscilloscope manufacturer to implement SureConnect technology. While measuring, the SureConnect technology checks in real time whether a test probe is in physical and electrical contact with the test subject. It is the right option for engineers performing quick and perfect measurements. The technology is available on the Automotive scope ATS5004D and as an option on the Handyscope HS5.

Assuring a good connection of a probe with a test subject may not always be easy. The subject under measurement may be dirty, oxidised or an (invisible) protective layer may be present.

Also, the test subject may be hidden, making visible contact confirmation impossible. SureConnect ensures users no longer have to question whether there really is no signal or that the probe did not make good contact.

Capacitative coupling between test probe and test subject can result in measuring a distorted version of the actual signal, wrongly suggesting a connection. SureConnect shows whether a good connection is present.

In addition to the connection test, a Handyscope HS5 with the SureConnect option offers resistance measurements on all channels. It is also an advanced and unique Ohm scope enabling the capture fast resistance changes in a graph, the ability to detect and locate carbon track defects in a variable resistor.

It allows the user to create resistance graphs of special resistors like NTCs and PTCs. Use e.g. channel 1 to measure the resistance of the PTC and channel 2 to measure the temperature. An XY plot will then show the resistance variation as a function of the temperature.

The Ohm scope uses the same inputs as the oscilloscope. Changing the measure leads is not required. The advanced protection against over voltage ensures that the Ohm scope withstands high voltages.
