Constraints on the size of email attachments depend on email client, email server, carrier, and other variables.

Illuminance measurement files are larger than the files generated by other GENNECT Cross functions because they contain drawing images and photographs, making them more likely to run afoul of these types of restrictions.

Cloud storage can be used to share files that are too large to send by email.

Consider using GENNECT cloud, a cloud service operated by Hioki specifically for its GENNECT line of services (free and paid plans are available).
