Buying Guide for Best Automotive Oscilloscope?
Now that you have gone through the recommendation list, you must be pretty excited to get yourself one of the devices, right? Well, before you do jump into making a purchase decision, you will have to keep some crucial things in mind. They are as follows:
Before anything else, you will have to consider the display. As we have mentioned earlier, a device with a bad display would be pretty hard to operate.
Keeping that in mind, you should shoot for the ones that pack a relatively large-sized panel on the front. Those will be much easier to operate. Also, you will be able to navigate through the different functionalities pretty quickly with those.
Even though most of the devices you will stumble upon will offer you all the basic functionalities, you might require advanced features sometimes. Most of the intricate wave transmitting parts that are in the car will require some advanced features.
So if you want to stay on the safe side, you should shoot for the ones with some advanced features aside from the basic ones.
- Coding Capabilities
Some of the units that are in the market will not support ECU coding capabilities. With those, you will be limited to the programs that come built-in.
Even though you will not have to modify the codes for most of the cases, having that capability is always a plus point. That is why we suggest going for the ones that support ECU coding.
- Battery Life
The thing that is going to power these devices will be a lithium-ion cell. And you should keep the capacity of the battery if you want to carry out prolonged maintenance tasks.
It would be a bit hard for you to do all the diagnosing tasks with something that can only stay powered on for half an hour. That is why you should opt for the ones that sport large-sized batteries.
- Internal Storage
You might not need to save the waveforms all the time. In fact, some of the parts can be diagnosed right from the device itself.
However, if you do want to diagnose intricate parts, you might need to store the waves and transfer them to another device.
In those cases, having internal storage for oscilloscopes is a must. For that reason, you should factor in whether the unit has internal storage built-in or not.
- Wireless Functionalities
If you are rocking a car that is relatively modern, it is highly likely that most of the parts will have a wireless chip. Connecting to those with a wired-only device would be quite impossible. In such cases, you should only shoot for the ones with both wired ports and wireless chip in it.
How to Use an Automotive Oscilloscope?
If you are fairly new to these devices, you might not have an idea about the operating procedure of them. Well, let us give you a brief idea about the process of using them. The steps are as follows:
Step 1: Power on the Device
Before anything else, you will have to power on the oscilloscope. If you are using an Android OS-based system, you will first have to turn on the power button and turn on the device accordingly.
Step 2: Connect It with the Parts
After turning on the device, you need to connect it with the part you are trying to diagnose. If the part has wired connectivity ports, connect it with the wire that you have received with the device.
And if the part has a wireless chip on it, connect it by going into your device's wireless settings.
Step 3: Start Monitoring the Waveform
Now that you have connected the device with the part you want to diagnose, you will have to make the part operate for a while.
After operating for a couple of minutes, the device should be able to capture the waveforms. Once you have all the required data, you should compare the waveforms with the standard ones.
Step 4: Make Adjustments If Necessary
After getting the waveforms, you need to make appropriate adjustments to the parts if necessary.
Frequently Asked Questions
1. Are oscilloscopes just another scan tool?
No, these are not regular scan tools. Yes, they are capable of scanning waveforms like the other tools. But these offer you the capability of making adjustments to the connected component after scanning.
2. Is it necessary to get a oscilloscope with a display?
If you get an oscilloscope without a built-in display, you will have to connect it with other display devices to monitor the waveforms.
And that can be a bit of a hassle sometimes. That is why getting one with a display is always convenient.
3. What can a technician do with an oscilloscope?
The technicians who have an adequate amount of knowledge of oscilloscope can make OE-level diagnosis to your parts. You will not have to rely on your OEM for fixing the malfunctioning parts.
4. Why is my oscilloscope not connecting with the parts of my car in the wireless mode?
If that is happening to you, it is highly likely that the device is not compatible with your vehicle. However, you can try to connect it with wires if you are not able to connect wirelessly.
5. Are oscilloscopes worth it?
According to us, they are very much worth it because of offering you the ability to make an OE-level diagnosis. If you can master operating them, you will not have to rely on a mechanic if a part fails to operate optimally.
Hopefully, we were able to provide you an adequate amount of knowledge about oscilloscopes. To conclude, we hope that our buying guide and recommendation list was effective enough that it is now easier for you to choose the best automotive oscilloscope.
