Common questions
Are the apps free?
Yes. All calculators are free and work offline once installed on your phone.
Can I rely on the calculator results for design?
They are for first-pass and field use. Always confirm against your project standards and vendor data before final design or calibration.
Are the courses free?
Yes, all courses are free while they are being written. Choose "Courses: request a course / notify me" in the form to request a topic or to get an email when new chapters are published.
Should I ask here or in the Community?
Technical questions that others could learn from are best posted in the Community, where many people can answer. Use the Help Desk for private or account questions.
Can I contribute study material?
Yes, please! Choose "Study materials" and describe what you'd like to share.
