MEASUREMENT PROCEDURE 

15

Note:

 The “ATC” tag blinks and automatic temperature 

compensation is disabled if the temperature exceeds the 

10‑40 °C / 50‑104 °F range.

Note:

 Temperature is not displayed in Baumé mode.

4. Remove sample from the sample well by absorbing on a soft

tissue.

5. Using a plastic pipette, rinse prism and sample well with

distilled or deionized water. Wipe dry. The instrument is ready 

for the next sample.
