Check the Temperature Control using the Boil Test
To check the ANKOM
2000
Fiber Analyzer temperature control, do a Boil Test once per month as specified in the
procedure below.
1. Disconnect cubitainers if connected.
2. Fill a pitcher with approximately 2L of hot water (50 ˚C or above) and set aside for later.
3. Turn on the instrument. Remove the bag suspender from the vessel.

(Should be between 5-10 VDC)
b. Pour the 2L of hot water into the digestion vessel so that the
glass level sensor tip is under water.
c. Record the voltage after pouring in the water. _______V
(Should be between 0-3 VDC)
Agitation and heat begin automatically.
8. Do not close the lid. Occasionally stir the water to ensure uniform heating.
The water should begin to boil in 5-15 minutes.
9. When a strong boil is reached, stir the water in the vessel and record:
a. The temperature on the controller. _______˚C
b. The temperature on a calibrated thermometer. _______˚C
(Place the thermometer near the probe at the bottom of the vessel.)
