Appendix 1 - Unpacking and Inspection

Inspect the outside of the shipping carton for damage. If damage is detected, contact

the carrier immediately. Remove the instrument from the shipping container. Be

careful not to discard any parts or supplies. Confirm that all items on the packing

list are present. Inspect all assemblies and components for damage. Save the original

packing carton. Carriers typically require proof of damage due to mishandling.

The following components are included with the purchase of the 5200A instru-

ment:

Conductivity, DO, and pH

values are effected by temper-

ature. If conductivity, DO,

and pH values are incorrect,

verify that the temperature

probe is working correctly.

If the temperature probe is

reporting incorrect values,

conductivity, DO mg/L, and

pH values are not reliable.

sation and conductivity -
