3. Change the source fluid’s temperature to 50 °C ± 2 °C. Take
extra care while working with
hot fluids.

5. Allow at least 20 seconds for the power-on self-test to
complete and the temperature display to ready a stable temperature. Confirm all LEDS are illuminated
green.
6. Release the clamp, and establish a fluid flow of 100 ± 20 mL/min.
7. With the thermometer, confirm the temperature of the fluid at both the input and output end
of cartridge.
8. The Over-Temperature alarm sounds within approximately 20 seconds or less of the output
fluid temperature reaching that of the input fluid level.
