Handy little software for fillable PDFs
Create fillable PDFs in minutes with PDFfiller. We use a lot of paper forms and it wasn't until recently that we began transferring all our old school paper and pen documents to these nifty fillable PDFs that folks can easily and conveniently complete and submit online.
Sometimes PDFfiller lags a bit but it's not annoying enough to stop using. Overall, I'm very pleased with the product.

Billing, invoices and subscription
Kara was excellent help in clarifying payment and free trial with me. Very friendly and helped solve the issue in seconds. Conclusion, the invoice can only be downloaded after the free trial has ended and subscription actively kicks in.

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
MTBF is a basic measure of an asset's reliability. It is calculated by dividing the total operating time of the asset by the number of failures over a given period of time. Taking the example of the AHU above, the calculation to determine MTBF is: 3,600 hours divided by 12 failures. The result is 300 operating hours.
How do you calculate reliability of MTBF?
Calculating MTBF To calculate the MTBF, you divide the number of hours by the number of failures. In the case of the five light bulbs that were tested, which had a failure rate of 4 per 3,647, you determine the MTF as 3,647/4 = 909. The MTBF is therefore 909 hours.
How do you calculate failure rate from MTBF?
If the MTBF is known, one can calculate the failure rate as the inverse of the MTBF. The formula for failure rate is: failure rate= 1/MTBF = R/T where R is the number of failures and T is total time. This tells us that the probability that any one particular device will survive to its calculated MTBF is only 36.8%.

Taking the example of the AHU above, the calculation to determine MTBF is: 3,600 hours divided by 12 failures. The result is 300 operating hours.
What is MTBF in maintenance?
Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system, during normal system operation. In addition, units that are taken down for routine scheduled maintenance or inventory control are not considered within the definition of failure.
How can I improve my MTBF?
Improve preventive maintenance processes. If done well, preventive maintenance has the potential to drastically increase MTBF. Conduct a root cause analysis. Work towards condition-based maintenance. What is MTBF? What is MTT?
What are the measures of reliability?
There are two distinct criteria by which researchers evaluate their measures: reliability and validity. Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability).
How do we measure reliability?
inter-rater reliability. Test-retest reliability. Parallel forms reliability. Internal consistency reliability.
