OPERATION UNDER UNUSUAL CONDITIONS
EXTREME COLD.
CAUTION
This kit must be protected from temperatures below 32F (0C):
The chemicals in the kit can be rendered useless and equipment damaged if allowed freezing.
All tests must be performed with equipment and samples above 32F (0C).
EXTREME HEAT.
All tests must be performed with equipment and samples below 125F (51.70C).
DUSTY OR SANDY ENVIRONMENT.
a. Keep equipment in closed case or covered until ready to use.
b. Use covers (coat, blanket, etc.) if possible to protect test area.
c. Keep test equipment, water samples, and solutions as clean as possible during and between tests. Keep lids tightly closed
and open only when needed. Cover beakers when in use.
SALT AIR OR SEA SPRAY.
a. Salt presents a serious corrosion problem and all equipment coming in contact with salt water or salt fog should be
flushed or sponged with fresh clean water as soon as possible then dried thoroughly.
b. During tests, be careful not to contaminate samples or solutions with any salt water or spray. Perform tests as quickly as
possible and clean equipment thoroughly between steps.
UNCONTROLLED FIELD CONDITIONS.
a. When demineralized or distilled water is not available, use cleanest water available (drinking water, clear Stream, etc.) to
fill the wash bottle containing Demineralizer.
b. Use water from wash bottle whenever demineralized or distilled water is called for to clean equipment and prepare test
solutions.
c. Test wash bottle water periodically to check effectiveness of Demineralizer. Test water-using Total Dissolved Solids
meter. A reading above 750 PPM (750 mg/l) indicates that the Demineralizer is no longer effective and that the wash bottle
must be replaced.
ELECTROMAGNETIC PULSE (EMP) ENVIRONMENT.
a. Keep all electronic equipment in its proper place inside the case, keep closed and latched.
b. Remove the electronic equipment from the case only when and if it is absolutely necessary and return it as soon as
