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]

Display Road Speed from ABS using a Maths Channel on PicoScope Use an ABS Sensor to calculate Road Speed from ABS using Maths Channel. You can create a speed waveform in km or miles per hour. Most ABS Sensors use a toothed wheel to detect wheel rotation, every time a tooth passes the sensor a pulse is generated. In this … [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 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 * I = P. You can even choose Watts as a … [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]
Vehicle Battery, Starter Motor, Alternator and Regulator Test Garage Lube imports and distributes PicoScope Automotive Diagnostic Equipment. One of the many tests that PicoScope can do, just by starting the vehicle, is a comprehensive Vehicle Battery, Starter and Alternator analysis. Two inexpensive kits, the 2-Channel and 4-Channel Diagnostic Kits which include an oscilloscope, test leads, probes and a 2000A current … [CLICK TO READ MORE]
Key Specifications – Which Oscilloscope is Best? Update: Added comparison to a professional OBD tool scope facility – Scope C An oscilloscope is an essential workshop tool. There are many scopes on the market, so how do you choose the best for your application? The answer is found in the scope’s specifications – that boring list of figures lurking at … [CLICK TO READ MORE]
