What if the leaf length isn't measured accurately with the CI-203?

If your CI-203 (or CI-203CA) is not measuring length accurately, you may be losing the length value for either or both of the following reasons:

a) The user may not be pulling the longest portion of the leaf exactly perpendicular to the roller.

b) The user have missed the very start of the leaf. Noting that only the longest petioles allow for complete leaf measurements.

These factors should be considered by the researcher and necessary adjustments made. The area measurement is typically more significant and more accurate than the length measurement, because it is based on two different vectors and sensing mechanisms.

Area, however, is still subject to the 2 potential sources of error listed above, though to a lesser extent. If you think your instrument is not measuring length accurately, please email support@cid-inc.com for further assistance.
