Performing a Temperature Range Adjustment
You can adjust your instrument over the whole temperature range to reach the
maximum accuracy for measurements at different temperatures than 20 °C.
During the temperature range adjustment, an air adjustment is performed at
40 °C and 60 °C, then a water adjustment at 60 °C and 40 °C.
The whole adjustment takes about 30 minutes.
The adjustment procedure can be aborted by tapping <Cancel>.
1. Tap <Menu> and select
"Checks/Adjustments > Other Adjustments >
Density Module > Temperature Range Adjustment"
.
2. Follow the instructions on the screen.
3. Check that the water is filled without air bubbles.
TIP
If the water was filled without air bubbles, you can ignore a possible error
message "Density Condition: filling warning" during the adjustment routine. The
coefficients for the FillingCheck
TM
function are also adjusted during the
adjustment procedure.
