Revolutionary real-time probe connection verification.

TiePie engineering is the first oscilloscope manufacturer to implement SureConnect technology. While measuring, the revolutionary SureConnect technology checks in real time whether a test probe is in physical and electrical contact with the test subject. SureConnect is the right option for every engineer for performing quick and perfect measurements. SureConnect is available on TiePie automotive USB oscilloscopes 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, oxidized or an (invisible) protective layer may be present. Also, the test subject may be hidden, making visible contact confirmation impossible. As can be seen in the following video, capacitive coupling between test probe and test subject can result in measuring a distorted version of the actual signal, wrongly suggesting a connection. SureConnect however immediately shows you whether a good connection is present.

Resistance measurement

The SureConnect option also provides the ability to perform resistance measurements. It is not just a simple multimeter to measure (contact) resistance, but it is also an advanced and unique Ohm scope:

  • Capture fast resistance changes in a graph.
  • Detect and locate carbon track defects in a variable resistor.
  • 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.

This unique Ohm scope with SureConnect is the first fast Ohm scope in its class.
