Is there a limit on the size of image files that can be loaded?

Illuminance Measurement

The Android version of GENNECT Cross can load image files with a resolution of up to 3,072 × 3,072 pixels.
The iOS version of the app does not have a maximum resolution, but users are recommended to limit the resolution to about the same maximum as Android (3,072 × 3,072 pixels). Although the specifics depend on the specifications of the handset in question, use of large image files may cause app operation to lag. Hioki does not recommend using image files whose resolution is higher than necessary.

As a general rule, a resolution of about 300 dpi is sufficient to ensure that printed text appears crisp and clear.
