WARNING
Handling samples with temperatures of more than 70 °C bears the
danger of heavy burns.
• Make sure you wear protective clothes or ensure alternative protection
from burns when handling high temperature samples.
WARNING
SG-Ultra Max
is not insulated against high voltages. Measuring samples
under high voltage (e.g. in energized battery banks) bears the risk of an
electric shock.
• Define appropriate testing procedures and safety measures to protect
yourself from any electric shock.
NOTICE
Before performing a measurement, make sure that the wetted parts are
resistant to the sample (see appendix A.3).
NOTICE
Samples containing dissolved CO
2
create bubbles in the measuring cell
rendering the measurement results invalid. Degas the sample properly
before measurement by:
- boiling it for several minutes,
- stirring it vigorously for 5 to 15 minutes until bubbling ceases or
- putting it for approximately 5 to 10 minutes into an ultrasonic bath
until bubbling ceases.
