METTLER TOLEDO DE40/50/51 Density Meter 31

8.2 Measuring temperature

This option is used to set the measuring temperature.

Enter your measuring temperature

(from 4 °C to 70 °C, 4 °C to 90 °C

for DE40) and confirm with

<ENTER>.

Note: After changing the set temperature make sure to allow enough time for the instru-

ment to warm up.

To increase the temperature: To decrease the temperature:

8.3 Measurement stability

This option is used to set the measurement stability, which allows to shorten the measuring

time. See section 3.2 "Measurement principle" for more details.

Enter your stability (0, 1 or 2) and confirm with <ENTER>.

0: Maximum stability. The measured signal (T-value) has to be stable before the density is

accepted. Longest measuring time (Time-0).

1: High stability. The final T-value is extrapolated, and the density is calculated. Medium

measuring time. ( Time-1 is approximately 1/2 of Time-0) .

2: Low stability. The final T-value is extrapolated from less values, and the density is

calculated. Lowest measuring time. ( Time-2 is approximately

of Time-0).

Note: Stability is fixed to zero when viscosity correction is active (section 6.2).
