Error Message Notes
thermistor Unable to read a reasonable thermistor value. Thermistor faulty or
faulty disconnected, Main board problem, or ambient temperature out of range.
safe A temperature of over 50°C detected on one or more of the 4
temperature thermistors. Temperature will be shut off and remain off until a successful
limit exceeded completion of power-up reset.
low light Not enough light detected to make an accurate measurement. If doing a
cuvette read, the cuvette door may be open.
unable to cal Too much stray light detected on power up, faulty or disconnected
dark current preamp boards.
signal level During a cuvette read, could be due to cuvette door being open.
saturation
reference level During a cuvette read, could be due to cuvette door being open.
saturation
plate air cal fail, Minimum signal/reference ratio not met during air calibration.
low light
cuv air ref fail
stray light Light leak in read chamber or cuvette door open. Could also be a faulty
pre-amp board
gain calibration Power-up calibration and check of signal path gain is out of tolerance.
failed Could be due to bad or disconnected pre-amp or excessive stray light.
reference gain Power-up check of the Reference amplifier's gain out of tolerance. Could
check fail be due to bad or disconnected pre-amp board or excessive stray light.
