Calibration Equipment & Standards and Calibration Software
8月 08, 2019
When I show calibration professionals the capabilities of our newest long-scale digital multimeter, the thing they’re most excited about is how much it can do in one box. The new 8588A Reference Multimeter takes everything that the 8508A can do and improves upon it, while adding capabilities that were not available before.
“What’s going to most interest many people is the 8588A’s ability to digitize”

We’re proud to feature this interview with one of our team members who helps customers move forward with Fluke Calibration. Looking for a temperature calibration product? Contact Jordan Crepps at 425-446-6830.
Many professionals get their start in calibration and metrology via military service and training programs such as the Airforce's PMEL (Precision Measurement Equipment Laboratory). Fluke Calibration metrology specialist Jordan Crepps got into metrology via Microsoft.

This is a story about how a community comes together to save a lake. Lone Lake is a 90.3 acre lake on the south end of Whidbey Island, Washington. Popular with boaters, swimmers and trout fisherman and ringed by homes, in 1996-2003 it was invaded by waterweeds that reduced access and interfered with the fish. Residents and local environmental organizations tried to fix the problem by alternately applying herbicides to kill the plants and stocking grass carp to eat them.

Dry-block calibrators vs. temperature baths: (left) portable temperature bath, (middle) hand-held dry-block calibrator, (right) standard temperature bath
Temperature sensors are typically calibrated by placing them in a stable temperature source and comparing their output to the output of a calibrated reference. Two common sources are dry-block calibrators and temperature baths, but which is right for you? Let’s start our dry-block calibrator vs. temperature bath analysis by defining each....

Fluke Calibration engineering fleet spans the globe, several generations, and numerous disciplines: covering both calibration and engineering disciplines. When the 8588A 8.5-digit Reference Multimeter and the 8558A 8.5-digit Multimeter launched, one engineer on the project humbly stated those advances were “simply clever engineering.”
What is innovation if not clever engineering that is directed towards solving customer problems?
Solving tough engineering challenges is what engineers do. It’s...

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...

What knocks a digital instrument “out of calibration?”
Three common causes of calibration problems are:
Component shift. First, the major components of test instruments (for example, voltage references, input dividers, current shunts) can simply shift over time. This shifting is minor and usually harmless if you keep a good calibration schedule; this shifting is typically what calibration finds and corrects.
Drops. Suppose you drop a current clamp — hard. How do you know that clamp will...
