Injector Waveform – High Speed with Regulation Understand high speed injector waveforms with switch-mode current regulation. We analyse waveforms captured by a PicoScope showing injector current and voltage from idling diesel engines. The vehicles’ waveforms shows cycles with two pilot pulses followed by a main pulse. Pilot pulses are used to even out diesel delivery during idle, which reduces the … [CLICK TO READ MORE]

Parasitic Drain Current Testing A parasitic drain current test can take place over many hours. The battery in your current clamp might run down so using a resistor to measure current, calculated using a PicoScope maths channel is a solution. This article builds on the Pico’s Parasitic Drain Current Test. Choosing a Resistor P R Max I 5W 0.1Ω 7A … [CLICK TO READ MORE]
CAN Bus Testing with PicoScope 6 Also see the Can Bus Test on our training website. The examples in the Maths Channel Basic Tutorial might look contrived but they can be very useful. Use A * B to determine the instantaneous power in a circuit if one of the channels is a current and the other a voltage: V * … [CLICK TO READ MORE]
Harness the Power of the PicoScope Maths Channels The PicoScope Maths Channel allows you to perform calculations on the fly as your PicoScope displays a waveform. It creates one or more new waveforms which show the result of the calculations. These articles are a short course showing you how to use them. Math Channel Course Agenda Built-in formulae for simple … [CLICK TO READ MORE]
Pressure Transducer A PicoScope can be much more than an electrical diagnostic tool. Add the high speed WPS500X Pressure Transducer that measures pressures up to 34bar (500psi) and reacts in one ten-thousandth of a second. It can also be used to measure vacuum and is compatible with air, coolant, petrol, diesel and lubricant oil. With the unparalleled speed, resolution and … [CLICK TO READ MORE]
