SCALE CALIBRATION SERVICES
When is the last time you’ve had maintenance and calibration performed on the scales you use for your business or laboratory? If you can’t remember, and don’t have a written record of it’s completion, it’s not being done frequently enough. Accurate Scale wants to answer your questions on why scale calibration is so important, and how often service should be done to keep them in optimal working condition.
WHY DOES A SCALE NEED TO BE CALIBRATED REGULARLY?
Scales Ensure that Inventory is Accurate
To keep inventory as accurate as possible, scales should be routinely calibrated to make certain that when orders are received or shipped out to customers the weight is correct and that employees are taking the correct amount from stock. This ensures that there is no discrepancy between what comes in and what goes out.
Scales can be Susceptible to Environmental Factors
Conditions such as humidity, temperature, vibration are environmental factors that can impact the accuracy of a scale. Humidity and temperature can react with a material being tested, or the scale. An excess of water in the air can cause corrosion inside of the scale. Temperature increases the resistance capacity of a metal, therefore, and increase in temperature will result in an increase in resistance which will show up as a higher weight.
Scales Have an Accuracy “Drift”
Even well made measuring equipment begins to degrade. The results of the scale will become less accurate the longer the intervals between calibrations. Scales that aren’t calibrated will become unreliable and give imprecise readings. You can prevent this accuracy “drift” through re-calibration of your device.
Scales will Undergo Diagnosis and Repair
A regular calibration schedule is important because this is the time when flaws in the functioning of the scale can be detected. We correct these issues and the scale can be put back in service. Our technicians are trained to make sure your readings are repeatable and at the same time, look for any physical damage that will require repairs when calibrating the device.
WHEN SHOULD A SCALE BE CALIBRATED?
At Manufacturer Recommended Intervals
The manufacturer of the scales you use will usually provide a timeline for calibration of the device. Maintenance schedules can vary because of the material from which the scale is constructed and the quality of the load cells and wiring. Many hours of testing has been done to analyze the quality of this piece of equipment. Ensure that you have the scale re-calibrated according to recommendation listed in the users manual.
After a Shock to the Scale
It’s a reality that accidents happen. If a scale is dropped, or has a chemical spilled on it this can damage the scale and cause imperfect readings from the device. It’s critical that a calibration should be done if a scale is subjected to significant jostling or a liquid spill. The scale should also be re-calibrated if it is moved to another lab. Different locations can have unique conditions and this
Before and After a Major Project
When a major project is about to begin, you want to make sure all the data you collect is reliable. Before you conduct any work and record any numbers, you need to conduct calibrations on all scales being used. During a significant project your scales have undergone heavy use, you should have a calibration done at the end of a project as well. This will ensure that they are in perfect working order for the next time they are utilized.
