“Insufficient power to write data” reported.

• Recharge the Ni-Cd battery pack, or replace it with a freshly charged Ni-Cd pack

or two AA Alkaline cells.

When transferring files to a PC, data is transferred, but there are repeated checksum or

device IO errors.

• Reboot your PC and start again. See the advice on RS232 communications in the

SunScan Tutorial (p28).

SunScan or BFS give inconsistent light readings.

• Make sure the diffusers are clean and that the desiccant condition indicators are

blue. See the advice on PAR calibration in Measurement Options (p49).
