There are three common methods for calibrating temperature sensors:
Calibrating just the electronics with a simulator
Calibrating both the electronics and the sensor in a dry-well
Calibrating both the electronics and the sensor in a dry-well with a reference thermometer
Here is a quick look at these methods and the pros and cons of each.
Calibrating just the electronics with a simulator
To calibrate the electronics of a temperature measurement/control system, a temperature simulator takes an...

One of the qualities of Fluke Calibration test and measurement equipment is excellent longevity. With regular care and maintenance, Fluke calibrators can last for many years and become staples of the calibration lab. Moreover, many of our customers pride themselves on their ability to repair older equipment, making Fluke Calibration products assets that provide a return on investment for decades.
When we say a calibrator is “end of life” or "end of service" it can be easy to assume we mean any...

MET/CONNECT Calibration Integration Software
MET/CONNECT, our new calibration management software API, allows you to use MET/CAL software without an asset management application. In other words, you no longer need MET/TEAM Test Equipment Asset Management Software to run MET/CAL if you already use a different asset manager or if an alternative solution better fits your requirements. We’re partnering with other calibration asset management software vendors so you can use MET/CAL as you want to,...

Customers and people at Fluke often ask me questions about calibration intervals:
How often should a unit be sent back for recalibration?
Are there any “rules” for this?
A few years ago, I wrote an application note on establishing calibration intervals on Fluke products, but there still seems to be some confusion on this issue.
What is a calibration interval?
A calibration interval is the period of time established for a test instrument to be returned for recalibration. We recalibrate...

Technician calibrating humidity sensors using the Fluke 5128A humidity generator / calibrator
Humidity sensors are a crucial component of quality control in a manufacturing environment. Often, they are found in “clean rooms” (not to be confused with operating rooms) where a tightly controlled environment — meaning controlled temperature, humidity, and air purity — is critical to product quality and reduction of environmental hazard risks.
Humidity sensors can pose some...

The Fluke 8588A & 8558A Benchtop Multimeters & Roger Peniche, Director of Engineering at Fluke Calibration
Engineering innovation to solve customer problems
This year on World Metrology Day, I spent time reflecting on the dedicated engineers I’ve had the pleasure to work with during my tenure at Fluke Calibration and the innovations they’ve dedicated their careers to achieving. Our engineering fleet spans the globe, several generations, and numerous calibration and engineering...

Choosing a calibration management software application requires careful investigation. Here’s a checklist of criteria to keep in mind.
Does the calibration management software automate your calibrators?
Does it automate your devices under test?
Are calibration procedures available or can you create them easily?
Does the manufacturer offer training?
Does the manufacturer offer support? What kinds of support?
Telephone
Knowledge base
User groups
Bulletin boards/user forums
Does the...

The best/proper method to clean your infrared calibrator target
The black body paint on the target of your infrared calibrator is very delicate. To remove the dust or debris from the paint, the only thing you can do is use compressed dry air. The dry air must have no oil and no water in the line or hose. Use a filter on an air hose to remove the oil and an air dryer to remove the water. Have the compressed air set to about 100 psi.
Some items like compressed air in a can will contain a...

If you are calibrating a medium to high accuracy RTD, you will probably use the characterization method of calibration. Characterization is the type of calibration in which the device under test (DUT) resistance is determined at several temperature points and the data are fitted to a mathematical expression.
To calibrate an RTD, perform these steps:
Place the reference probe and the DUTs in the temperature source. Make sure they are all placed as close together as possible, in a radial...
