Your rental kit includes all the instrumentation, accessories, software, and manuals to do your job, plus copies of the current calibration certificates for the instruments. When you get the rental, you'll see the checkout sheet we use to confirm everything is included before we ship. Please use the checklist to verify you're returning all the parts, and send it back with your rental. That way, you won't be charged for any missing accessories.
For reporting purposes, your kit includes a printed copy of the instrument's calibration certificate. Still, some customers have told us that making copies of calibration certs isn't possible (because they're working from the field), or they forget. So, the night your rental ships, we send you an e-mail with the digital calibration certificate (PDF) attached, so you'll have it on file to keep with your project documentation and reports.
