Wavelength test failed

Error ID: 7890
The automatic wavelength check after lamp ignition has failed. When the lamp is
switched on, the detector waits 1 min to warm-up the lamp. Then a check of the
deuterium emission line (656 nm) via the reference diode is performed. If the
emission line is more than 3 nm away from 656 nm, the error message is
generated.
