Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and
national regulations.
Ultraviolet (UV) light exposure. Exposure to UV light can cause eye and skin damage. Do not look
directly into the measurement path when probe is in operation. Protect eyes and skin from direct
exposure to UV light. Wear all appropriate personal protective equipment.
Do the steps that follow to validate the probe calibration.
1. Go to the main menu, then select Sensor setup.
2. Select the applicable sensor, if necessary.
3. Select Maintenance.
4. Set the outputs on Hold.
5. Remove the probe from the tank or flow through unit.

(offset, factor, signal average and matrix calibration for the NT3200sc, if applicable).
• The next line (next three lines for the NT3200sc) shows the values from the factory calibration
(factor, offset or matrix calibration).
Remove the tape and make sure that the back hole of the measuring path is free.
