RLC-5 V1.47 Known Bugs V1.47 may still have a problem with command C057 event 055, so avoid using that event trigger. Command 103 uses the third digit after the '*' for the sign digit rather than the second one; the second digit is ignored. Because of this, calibrating to anything positive and 999 or smaller works fine (example C103*100999). It is not possible to calibrate to a positive number larger than 999. It is not possible to calibrate to a negative number smaller than 1000 or larger than 1999. To reset the calibration for one of the analog lines, enter C103*L22 where L is the analog line number. This problem should be fixed in software versions 1.56 and later when they are available.
