S E C T I O N 2 GETTING STARTED 2.3 Setting Up the Osmometer While the instrument compensates for small changes that occur over time, moving the instrument to a different area or exposing it to too much air circulation will shift the osmometer’s reading and calibration points. The Temperature Drift scale allows you to determine when internal temperature has stabilized. The Temperature Drift scale appears on the screen whenever the instrument is in the “standby” mode, and it has completed two cycles. The instrument is considered stable and ready to operate unless the indicator is against the + or - marks on the scale, indicating a changing internal temperature that can affect instrument calibration. See Note below: NOTE: It is normal for the osmometer to undergo a significant temperature drift during the first few minutes of equilibration. The time required to achieve temperature stability depends on the initial instrument temperature, (typically 10 to 30 minutes) but may be longer if initial temperature varies more than 5 degrees from room temperature. NOTE: Under normal circumstances, leave power on to keep the instrument in a ready state and to maintain stability. (See Section 3.6) 21
