Basic steps in calibrating a grinder for espresso – Quaffee

You should calibrate the grind first thing in the morning, every morning before you open. And if the weather changes during the day, or if you think that conditions have changed, you should time a few of your shots to see whether you have to adjust the grind. Calibrating Your Grinder We prefer to calibrate using a Doppio (Double Espresso).


compaction parameters in real time. Your operator can now visualize the work as it is happening and the data can be accessed in the back office for full documentation of the compaction process. CONNECT Machine to machine communication allows compactors working on the same site to share their mapped compaction data with each other.

How Often Should I Inspect My CNC Grinding Machine?

To ensure satisfactory work when using a grinding machine, it is important to not only true but also dress the grinding wheel. These two processes should be carried out every time the grinding wheel is mounted on the machine. While super-abrasive...

2. Noise sources and their measurement

To approximate the integration time of our hearing system, sound pressure meters have a standard Fast response time, which corresponds to a time constant of 0.125 s. Thus, all measurements of sound pressure levels and their variation over time should be made using the Fast response time, to provide sound pressure measurements more ...

Wafer Thickness, TTV, Bow and Warp Measurement | Non ...

Figure above shows a wafer placed between two non-contact measurement probes. By monitoring changes between the upper probe face and the upper wafer surface (A) and the bottom probe face and the bottom wafer surface (B), thickness can be calculated. First the system must be calibrated with a wafer on known thickness (Tw). The area of known ...

Recommended Calibration Interval | NIST

This time-dependent behavior can be compared to the accuracy requirements of the particular application to determine an initial recalibration interval. Subsequently, recalibration reports should include "as submitted" and "post calibration" accuracy and precision data to validate and/or refine the interval.

How Often Should I Calibrate My Equipment?

Many types of measuring equipment will come with an owner's manual giving an approximate recommendation for how often it should be calibrated. This recommendation should be treated as the baseline standard, with your own analysis determining whether something should be …

Weld Repair - American Welding Society

Hi Guys, We are involved in welding of steel structures as per D1.1 requirements and we encountered frequent repair work on production welds after detected by UT. The type of defects were slag, lack of fussion and porosities only.
