ERROR MESSAGES
n OUT OF RANGE
If the message OUT OF RANGE is displayed when scanning a sample, the sample
may be over range or under range. If the sample is over range the sample should
be diluted and tested again (see Sample Dilution Techniques & Volumetric
Measurements, page14).
n BATTERY (optional)
If the symbol BAT appears in the upper left corner of the display when using the
battery pack, the battery needs to be charged. The SMART Spectro will turn off
if the battery power becomes too low.
n ERROR 1 TROUBLE WITH FILTER
There is a problem with filter positioning. This could be due to a dead motor,
bad connection to the motor, or a bad positioning detector. Contact LaMotte
Technical Service for help.
n ERROR 2 TROUBLE WITH SWITCH
There is a problem with the grating positioning. This could be due to a dead
stepping motor, bad connection to stepping motor, or a bad micro switch.
Contact LaMotte Technical Service for help.
n ERROR 3 TROUBLE WITH LIGHT
There is a problem locating the zero order light during wavelength calibration.
Contact LaMotte Technical Service for help.
n WARNING SIGNAL TOO WEAK
Not enough light is getting to the detector. Check light path for blockage.

n WARNING SIGNAL TOO STRONG
This can be an indication that the meter was accidently shut-off during
wavelength calibration. Shut meter off and restart.
n WARNING RAM BATTERY LOW
Clock battery needs to be replaced soon. If it fails all user tests and Datalog Data
