Count tolerance on a multimeter refers to the acceptable range of variation in the display reading, often specified as a percentage of the reading plus a fixed number of counts. For example, a multimeter might have a tolerance of ±1% + 2 counts, meaning the displayed value could be off by 1% of the reading plus or minus 2 digits. This tolerance helps users understand the precision of the measurement and the potential error in readings. It is crucial for ensuring accurate measurements in various applications.

Is 24.0 mfd a good test reading for a 24.5 mfd run capacitor with a multimeter?
That would depend on the tolerance of the capacitor. As the measured value is only about 2% below nominal and most capacitors have 10% or 20% tolerance it should be fine. However if it was a precision capacitor with for example 1% tolerance it would be bad.
Do the colour code readings tally with the resistance values obtained using the digital multimeter?
Yes, the color code readings should match the resistance values obtained using a digital multimeter, as the color bands indicate the resistor's nominal resistance. However, discrepancies can occur due to factors such as tolerance, temperature coefficient, or measurement inaccuracies. It's essential to ensure the multimeter is calibrated and set correctly for accurate readings. Always cross-check the resistor's color code and the multimeter reading for consistency.
Why is engineering tolerance important?
Because you can count on parts to not be perfect. So if you want them all to fit, the need some room for the grease.
What tool is used to check voltage?
by using a multimeter we can find line voltage.
Why does the multimeter show the RMS value of sine wave but not for the triangular wave?
Because your multimeter is not an adequate device for this kind of measurement. Use the correct multimeter to display the triangular wave value.

Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.

Count in multimeter?
The "count" of a multimeter refers to how large a number it can display before it has to change measurement ranges, and how many digits it shows total. This affects how precise a measurement the meter can display (note: this doesn't necessarily reflect absolute accuracy, just precision of the numbers it can report.) First, the total number of digits of the count matches the digit count of the display. A x00 count multimeter only displays 3 digits, while a x000 shows 4 digits. So a 200 count meter could read 19.9 volts, while a 2000 could read 19.91 for the same input. Second, the value of the first digit indicates when the meter needs to "move up" to the next range. A 2000 count multimeter would read 19.99 volts as 19.99, but at 20 would have to read 020.0, loosing a digit of precision. The same thing happens at higher and lower ranges, each time having to move when the top digit reaches 2. For comparison, a 4000 count multimeter would up-range whenever the top digit gets to 4, allowing it to read 20-39.99 volts with two decimal places where the 2000 cannot. I suspect, but cannot confirm, the count limits in digital meters are due to the A/D converter used, and the number of output bits it has. This matches up with the common count values being close to powers of two.
