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]
Analysing a Starter Motor A starter motor can be tested by measuring the voltage drop across the battery or by measuring the current being consumed by the motor. Much more information is available: Power; Impedance; Speed; and Torque, and only two channels are necessary for all of the tests. All you need is your PicoScope, a premium test lead with … [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]
Using an Automotive Oscilloscope for Industrial Applications An Automotive Oscilloscope for Industrial Applications? Dedicated controllers, computers, PLCs, VSDs have all helped increase the complexity of industrial systems. Generally, they are located in harsh environments. Automotive systems are also becoming increasingly complex and their environment is certainly harsh. Pico Technology have developed a range of automotive oscilloscopes that are rugged and … [CLICK TO READ MORE]
Introduction to Prop-shaft Balancing Please Note: The actual force exerted increases as the distance from the centre of the shaft to the centre of the mass (radius) increases. The actual force is measured in the PicoDiagnostic software as mass times by radius. As the radius, when balancing a drive shaft, is constant, we have ignored the radius and just used … [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]
