Unfortunately, several common causes can lead to calibration problems. Here is a look at the different situations you may experience, the issues, and the solutions.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>What is Calibration?<\/strong><\/p>\n<p>Instrument calibration is the primary process to maintain instrument accuracy. Calibration configures an instrument to provide a result for a sample within an acceptable range.<\/p>\n<p>The calibration involves using the instrument to test samples of one or more known values. The results are used to establish a relationship between the measurement technique used by the tool and the known values.<\/p>\n<p>The instrument will perform best when the intermediate points supplied in the manufacturer&#8217;s performance specifications are calibrated.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>What Knocks a Digital Instrument out of Calibration?<\/strong><\/p>\n<p>Three main categories will throw an instrument out of calibration.<\/p>\n<ul>\n<li><u>Component Shift<\/u>\u00a0\u2013 The significant components of test instruments can shift over time. This shifting is minor and usually harmless if you keep a calibration schedule. This shifting or drifting is what calibration can find and correct.<\/li>\n<li><u>Drops<\/u>\u00a0\u2013 Dropping an instrument can create gross calibration errors.<\/li>\n<li><u>Overloads<\/u>\u00a0\u2013 Exposing a digital multimeter to excess can throw it off. Many think this has little effect because the inputs are fused or breaker-protected. However, those protection devices may not trip on a transient. A significant voltage input can jump across the input protection device entirely.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Calibration Drift<\/strong><\/p>\n<p>Calibration drift is when a measuring instrument&#8217;s readings drift into an inaccurate territory over time. Drift can lead to measurement errors and related problems, including safety concerns.<\/p>\n<p>Avoiding calibration drift plays an essential role in maintaining measurement accuracy. No matter the equipment type, it is a problem that you need to be on the lookout for.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>What Causes Calibration Drift?<\/strong><\/p>\n<p>Calibration drift can occur naturally over time, particularly as the instrument gets regular usage in a lab. Therefore, it is difficult to prevent loss of accuracy entirely. However, there are some causes that your lab can avoid. Here are some of the most common causes of drift.<\/p>\n<ul>\n<li>Misuse, mishandling, and neglect.<\/li>\n<li>Environmental changes, such as in temperature or humidity.<\/li>\n<li>Exposure to harsh conditions, such as corrosive substances or extreme temperatures.<\/li>\n<li>Sudden mechanical or electrical shock or vibration.<\/li>\n<li>Frequent use and natural calibration degradation over time.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>SRP Has Calibration Solutions<\/strong><\/p>\n<p>Calibration problems can take the instruments out of the field and slow your operation.
