Calibration and Certification
- What is OIML?The International Organization of Legal Metrology (OIML), established in 1955, develops international standards and recommendations to ensure the accuracy, reliability and consistency of measuring instruments used in legally regulated applications.
- What is calibration?Calibration is the process of comparing a weighing scale’s readings against known reference weights to verify its accuracy. If the readings fall outside the specified tolerance limits, adjustment may be required.
- Do I need a calibration certificate?Our weighing scales are accuracy-checked before leaving the warehouse and are ready to use upon delivery without further checks. For industrial weighing scales, a free internal test report is provided with the scale and a third-party calibration certificate is available as an optional extra at an additional cost. It is not essential for normal use, but many companies require it for their internal quality records.
Maintenance
- How do I clean my scale or weight indicator?Unless the scale or indicator is rated IP67 or higher and the manufacturer’s instructions permit it, do not submerge it in water or pour or spray water directly onto it. Clean it using a damp, soft cloth or plastic scouring pad, clean water where possible and a mild, non-abrasive detergent. Do not use acetone, thinner, other volatile solvents, steel pads, wire brushes, scrapers or anything that could scratch the surface.
Operation and Connectivity
- What is baud rate?Baud rate is the speed at which data is transmitted between a weighing scale or indicator and a connected device. A higher baud rate generally allows faster communication.
- What is the “Auto-Zero” function?Often referred to as “zero tracking”, this means the scale will automatically set to zero when the scale activates, or if the weight is within a certain tolerance close to zero.
- Which weighing scales can be connected to a PC?Models equipped with an RS-232 serial interface can be connected to a PC. Weight readings can be viewed using serial-terminal software such as PuTTY, provided the correct communication settings are used. For automatic data recording, customized reports or integration with other software, please share your application and requirements so we can recommend a suitable model and solution.
Technical Specifications
- What are divisions?Divisions are the total number of increments between zero and the scale’s maximum capacity.
- What is the difference between readability and accuracy?Readability is the smallest weight increment a scale can display. Accuracy is how close the displayed result is to the true weight within the specified tolerance. A lower readability can show smaller weight changes but does not guarantee accuracy. Precision means producing consistent results; a scale can be repeatable but still inaccurate if it is not correctly calibrated.
- Which IP rating is suitable for each environment?• IP65: Suitable for dusty or wet environments exposed to splashes and low-pressure water jets. It is not suitable for immersion. • IP67: Suitable where equipment may be temporarily immersed in water. • IP68: Suitable for continuous or extended immersion under conditions specified by the manufacturer.
Product Selection
- How do I select the right weighing scale?Consider three key factors:
- Suitability: Choose a scale suitable for the material and operating environment.
- Capacity: Select a capacity higher than the heaviest item you will weigh.
- Readability: Choose the smallest weight increment required for your application.
- What are hazardous-area scales?Hazardous-area scales are specially designed for locations where flammable gases, vapours or combustible dust may create an explosive atmosphere. Gas-cylinder filling is one common application. Depending on the site and application, appropriate hazardous-area certification, such as ATEX or IECEx, may be required. We can provide certified weighing solutions for these environments.
- What are industrial scales used for?Industrial scales are used for a wide range of applications, including weighing goods and materials, counting parts, filling, mixing, recipe formulation, checkweighing and inventory control.
- Which models are suitable for heavy-duty floor weighing?For heavy-duty floor weighing, we recommend the SENS i10, Dini Argeo models and the CAS DH 5mm. These models offer strong construction, reliable accuracy and durability for demanding applications in warehouses, factories, logistics facilities and other industrial environments. The most suitable model depends on the required capacity, platform size and operating environment.
- Which weighing scale models are suitable for livestock?For livestock weighing, we recommend the SENS i10 and selected Dini Argeo models. These systems provide stable readings even when animals move and are available with heavy-duty platforms suitable for livestock applications.
