Measuring Spring Force Procedures

The video tutorial explains how to measure spring force using a digital scale. It covers the process for both coil and finger type springs, emphasizing the importance of zeroing the scale, recording readings, and recalibrating the scale for accuracy. The tutorial also provides guidance on replacing springs if pressures are too light and offers resources for further assistance.

What is the first step in measuring spring force?

• Pull all the way up to uncoil the spring

• Turn on the digital scale and zero it

• Mark the point where it is extended at least one diameter

• Place the hook with the roller bearings in the coil spring

What should you do after placing the hook with the roller bearings in the coil spring?

• Zero the scale

• Pull all the way up to uncoil the spring

• Record your readings

• Mark the point where it is extended at least one diameter

How do you determine the amount of measured spring force?

• By using a stopwatch

• By estimating visually

• By watching the large easy-to-read digital LCD display

• By using a ruler

What should you do to double-check your results?

• Repeat the process

• Ask a colleague to verify

• Use a different spring

• Use a different scale

What is the first step in measuring spring force on a finger type spring?

• Slowly return the spring to the resting position

• Pull all the way up to uncoil the spring

• Turn on the digital scale and zero it

• Use the leather strap and loop over the end of the spring finger

When should readings be recorded for a finger type spring?

• Only at the fully extended position

• From a new brush length to a fully worn brush length

• Only at the resting position

• From the start to the end of the process

What should you do if some spring pressures are too light during spot checking?

• Use a different method

• Recalibrate the scale

• Replace all springs

• Ignore the readings

How often should the Hellwig carbon scale be recalibrated?

• Never

• Only when it shows errors

• Periodically

• Every day

Where can you find the recommended spring pressures?

• In the chart provided

• On the digital scale

• On the spring itself

• In the user manual

What should you do if you need further assistance?

• Refer to the digit scale information sheet

• Search online

• Guess the solution

• Ask a colleague
