The 81486-20 is a digital-based panel meter, counter, and hour meter. It is generally used in industrial and commercial environments, where its multiple functions make it an essential component in the daily operations of the business. Panel meters are designed to aid in the reading and analysis of any readings taken in an electrical device. Counters are used to track and quantify the number of occurrences of any event. Hour meters are designed to measure how long a process or product has gone through a certain phase. The 81486-20 can be categorized as a Panel Meter-Counter-Hour Meter due to its ability to combine all three aforementioned pieces of equipment. It has two bicolor LED displays and two inputs for observing and adjusting voltage or current. It has a monitor output which can be used to provide a signal if desired limit values have been exceeded. As a counter, it can count both up and down, and as an hour meter it can store up to 480 hours of uninterrupted time.The 81486-20 has a variety of applications and can be used in many different industries. It\'s most commonly used in commercial and industrial settings, such as in manufacturing, automotive, aviation, and marine environments. It\'s also used in medical, food service, explosives and other hazardous material transportation, and military and defense operations.The 81486-20 includes a variety of features that can be used to ensure that readings are accurate and reliable. It has adjustable sampling rates and a low-battery indicator. It also has overload and undervoltage protection, meaning that it will shut down automatically if the inputs are at either end of the range. It is also protected against shock and vibration, making it tough and durable.When used as a panel meter, the 81486-20 is capable of measuring voltage, current, frequency, power, power factor, and resistance. As a counter, it can count up and down up to 10,000 increments, with a resolution of 1 unit. As an hour meter, it can track up to 480 hours of uninterrupted time.The working principle behind the 81486-20 is fairly simple. For measuring voltage, current, etc., the output is connected to the input of the device. On the LED display, the readings are then measured and displayed. For counting up and down, the input is connected to a trigger pulse, which is counted by the device.In conclusion, the 81486-20 is a versatile digital panel meter, counter, and hour meter. It is ideal for industrial and commercial settings, where its multiple functions and features make it an essential component of operations. With its adjustable sampling rates, overload and undervoltage protection, and shock and vibration resistance, it is reliable and accurate in its readings.
