The safe continuous input voltage to the VCI is a maximum of 60V and the scale of measurement in voltage can display from 100mV (10mV/division) up to 200V (20V/div) up the screen. The time base for both channels can be set between 50 micro seconds and 1 second across the screen. There are too many options to describe them all here, but if you hover your cursor over any icon or soft key a ‘tool tip’ pops up with a description (see Fig 8).
Trigger points can be set to be sure that signal recording starts where you want it to and waveform display options can be used to get the best results. Opened from the main menu, the oscilloscope screen can be viewed alongside the ESI 2.0 program and offers many customisable settings that enable you to effectively capture and display the test results you need. This means you can see in detail what is actually happening in an electrical circuit in real time. Fig 7 shows a PD injector and crankshaft sensor signal.
The beauty of using an oscilloscope is that it opens up a whole new dimension of system diagnosis by presenting to the user an accurate graphical representation of voltage over time. Now we’ll look at our Bosch KTS 570 two channel oscilloscope functions that can be used for even greater in-depth testing of electrical systems and components. A really useful additional feature of the KTS multi-meter is the circuit break and short circuit function, which you can configure to emit an audible warning signal when you conduct a wiggle test on the suspect harness to help you find wiring faults along a loom. You can connect a Bosch amps clamp with adaptor for non-intrusive current measurements to be displayed on screen. Another great feature is that, just like the actual value time profile display in ESI 2.0, the multi-meter graph can be paused, reviewed, saved and printed (if necessary) for reference (see Fig 6), showing battery voltage and current upon starting the engine.įor voltage and current readings, we have the choice of DC, AC or EFF (root mean square) settings on both channels and resistance measuring up to 1 M Ω on channel 1. This gives the user more convenience, depending on the measurements being taken. The readings can be shown in a numerical form, with a useful bar graph, or in a graphing trace format, with up to a minute across the screen.
KTS 570 BLUETOOTH SPEAKER PC
The test results will be wirelessly displayed on your PC screen, with the measurements taken by the probes attached to the KTS VCI which is connected to the vehicle (see Fig 5). Now you can overlay the multi-meter results screen over ESI 2.0 and see the serial diagnostic data and direct measurements side by side (see Fig 4). When the multi-meter is accessed via the main menu (see Fig 3) a new window will appear on-screen with the multi-meter display and measurement selection options. We’ll first take a look at the Bosch KTS multi-meter functions that can be used alongside the ESI 2.0 vehicle diagnostic program.
KTS 570 BLUETOOTH SPEAKER SERIES
For technicians that use a separate oscilloscope – such as the Bosch FSA 500 or FSA 720/740 series – then the KTS 540 is Please remember that if you have a KTS 540, there is no scope capability built into the VCI. This will give you confidence in your results and should certainly lead to an improved first time fix rate of your customers’ vehicles.įor this article, we’ll concentrate on the multi-meter and scope functions of the KTS 570. These values can be tested using the Bosch KTS multi-meter or oscilloscope, along with ‘guided’ fault finding instructions and technical data through ESI 2.0. In Bosch ESI 2.0, there are many Service Information System (SIS) repair instructions linked to an error memory code that will suggest a direct measurement needs to be made of the voltage supply, earth path, or signal/command wire or component resistance in the system (see Fig 2). Once a DTC is read from the error memory of a control unit, a good fault finding process is required to test the suspected component and its associated electrical circuit.
KTS 570 BLUETOOTH SPEAKER CODE
The kit contains high quality colour-coded test cables and probes, which use standard 4mm ‘banana’ type connectors. As we all know, often a Diagnostic Trouble Code (DTC) will only give a guide to the general area of a system that is suspected to be faulty or out of range. The good news is that if you own a Bosch KTS 540, then it already has a single channel multi-meter included and our flagship tool – the KTS 570 – features a two channel multi-meter or oscilloscope which is all ready for you to use (see Fig 1).
Many technicians consider a graphing multi-meter or oscilloscope an extra investment, along with all of the other equipment required to effectively work on modern cars today.
