What is a trimming potentiometer?
A trimmer potentiometer, also known as a trim pot, is a type of variable resistor or adjustable potentiometer that can adjust, tune, and calibrate circuits. These trimmer resistors are often used to initially calibrate equipment after manufacturing.
What is the symbol of a trim pot?
Trimpot Symbols
| Trimpot symbol (IEC standard) | Preset resistor symbol (IEC standard) |
|---|---|
| Potentiometer symbol (IEC standard) | Rheostat symbol (IEC standard) |
How do you install a pot trim?
Move the controller until it just turns on. Quickly push the controller in one direction and note how quickly the function’s speed rises from creep to maximum output. Adjusting the ramp trim pot will increase or decrease the time delay, or ramping of function speed from slow to fast and fast to off.
What is the difference between a trimmer and a potentiometer?
Resistors. Resistor trimmers generally come in the form of a potentiometer (pot), often called a trimpot. Potentiometers have three terminals, but can be used as a normal two-terminal resistor by joining the wiper to one of the other terminals, or just using two terminals.
How do trimmer resistors work?
What is trimmer resistor? A trimmer resistor is a variable resistor that is designed to be infrequently adjusted, usually just at the point of manufacture or when the unit is being recalibrated. They are placed along the circuit at critical points that need to be carefully tuned for optimal functionality.
How do you read a trimpot?
Usually, the value of the Pot is printed on its body. But the miniature “Trimpots” have codes to represent its value. For example, 102 (1K), 103 (10K), 104 (100K), 105 (1M) etc.
Is a trimmer resistor the same as potentiometer?
How do you read potentiometer numbers?
The first 3 digits on a pot are the manufacturer code. The last 3 or 4 digits are the date code. With 3 digits, the first digit is the last digit of the year, and the last digit is the week number. With 4 digits, the first 2 digits are the last 2 digits of the year.

WHAT DOES A or B mean on a potentiometer?
Potentiometers made in Asia and the USA are usually marked with an “A” for logarithmic taper or a “B” for linear taper; “C” for the rarely seen reverse logarithmic taper.
