Example: If the desired resistance for the antenna is 450 Ohms, then set the selector dial to read a range that includes 450 Ohms. Automotive multimeters are truly an excellent choice when it comes to measuring engine RPM, be it on your car on your motorcycle, if you know how to do it right, the results will be better than if you had seen the result on a tachometer, especially if you have had one of those tachometers that didn’t show the precise value, but had the rotating dial instead. To extend the life of a given relay, you must keep them cold for as long as necessary. Set the filters using a digital multimeter set to measure voltage in AC, put the leads on the outputs of the amp. "Properly set your gain" level 2. Clamp Multimeter has other names like current clamp, current probe, clamp-on ammeter etc as it used a pair of jaw which allow clamping around an electrical conductor to measure the current in a conductor without the need to make physical contact unlike a normal multimeter. When you have found it, you can check the wiring diagram to see which wires you should test and their characteristics. 4 - Unhook all speaker(s) from the amp, set the multimeter to AC voltage and hook up the leads to the + and - on one of the amp's channels. First of all, make sure that everything is turned off. I ran it like this a very simplified way to explain it) This is just to get you started. This only applies to the first time I tune the amp for a given antenna and band combination. This article explains how and why we fine-tune a room thermostat or wall thermostat by checking its heat anticipator using a mini ammeter. Turn the filters off (HPF down, LPF up) and play a test tone at the desired frequency that the filter will be set at. I the adjusted the bias using a piece of Popsicle stick that I had trimmed to fit the bias adjuster. About The Author. ROOT. I seriously doubt you should be worried about exact voltages unless you are worrying about overpowering some subs with far less power handling. I have the same type of settings on an old amp. We first covered how to set your gains by ear in the article titled “How to Tune and Adjust Amplifier Gains and Bass Boost”, however this is not a great method to use because all of our ears are different and we often can’t hear the most deadly distortion. 2.
