Troubleshooting Your Digital Weight Scale

A digital weight scale is more accurate than the old fashioned needle scales. It is also more sensitive to changes and movement. You have to stand correctly on the scale to get an accurate reading, but just as with any type of calculating machinery, the scale sometimes needs to be calibrated. If your weight is off and you're confident you haven't gained or lost, you need to check out the calibration of the scale and several other options that can be causing the problems. In this article we are going to give you a few of those options.

Setting the Scale

On the scale, there should be an adjustment device of some sort, a knob or slide, usually under the front part where you can see the weight as you adjust. You need that to zero the scale. Turn the scale on and see what it reads. If it is over or under zero, reset it accordingly. This should alleviate problems.

Using a Known Weight

To test the scale further, weigh some object of a known weight. Something such as a one-pound free weight will work. Set it on the scale and see if it is over or under. Try weighing a few more objects of known weight to give a more exact an idea of this scale’s accuracy.

Leveling the Scale

If the scale is off balance, it will cause an incorrect weight. Test the location of your scale to be sure that it is sitting on a level surface, and check that the scale’s little feet are all on and even. Also turn the scale over from time to time and clean the bottom since too much debris might interfere with the way the scale sits.

Make sure the shipping plate has been taken off the bottom if your scale is relatively new. Some models have one when shipping to avoid damage.

Checking for Electronic Trouble

If your scale is electric, make sure the plug is in correctly, and if there is a cable connecting from the body to the reader, make sure it is connected correctly as well.

Anything electric runs the potential to blow a fuse. If there is no display on the scale, this could be your problem.

If your scale is battery-powered make sure you have a fresh battery to install and check it again. A low battery can sometimes give an off reading, and of course, a dead battery will give no reading. If the battery itself wasn’t the problem, you might check the terminals next. Battery terminals can sometimes end up bent so they don’t make sufficient contact with the batteries. Check them to make sure you are getting a proper connection.

If you are showing a partial LCD reading, the connector may be loose. Pushing on the LCD may have the desired effect; if not, open the back and make sure it is connected. Don't drop or bang the scale around, as this can cause damage to the equipment inside and cause inaccurate readings.
