Analyzer setup - Section 5

5.3 Temperature calibration

You must have a temperature calibration kit to perform this procedure. If the Moisture Analyzer has been re-
cently used, allow at least 30 minutes before performing calibration.

Press the

Setup

button. Using the arrow buttons, scroll to TEMP CAL.

Press the

Enter

button. You are now prompted to remove the pan

handler and pan support. Replace the pan handler and place a tem-
perature calibration unit on the pan handler.

Note

: The unit

will not calibrate

with the pan support in place.

TEMP CAL

Press the

Enter

button to initiate the temperature calibration process.

Follow the screen prompts throughout the process.

TEMP CAL 100C

The dryer unit is heated to a temperature of 100°C. You can observe the
progress on the display as the dryer temperature and count down period
are displayed. After 15 minutes, read the thermometer through the
inspection window on the cover and enter this temperature. Using the
up/down arrow buttons, adjust the display reading to agree with the
thermometer. Use the left/right arrow buttons to highlight ACCEPT NEW
CAL, then press the

Enter

button. You have 10 minutes to make this

adjustment, otherwise the calibration is terminated.

TEMP CAL 160C

This is a two point adjustment (100°C and 160°C). The dryer unit now
heats to the second temperature (160°C). Adjustment of the temperature
is defined by two points. Proceed exactly as you did for the first tempera-
ture. After you have set the display to agree with the thermometer,
highlight ACCEPT NEW CAL, then press the

Enter

button. The display

returns to ANALYZER SETUP.

WARNING

: Be careful when removing the temperature calibration unit

from the dryer unit as it can be very hot. Allow it to cool down by open-
ing the cover before removing.

Remove the calibration unit. Replace the pan support and the pan
handler in their proper positions.
