6. SAMPLE PREPARATION, TESTING AND ANALYSIS
6.1. Balance Temperature Stability
The force balance in the MAX 5000XL is most accurate in a stable temperature environment. To maintain a constant balance temperature, whether the instrument is testing or idling, the instrument heats the balance at initial
The balance temperature stability icon is in the lower left corner of the LCD when viewing the main screen. It is a triangle with a line on top. A horizontal line 
indicates that the balance is temperature stable. A tilted line 
(as shown in the picture) indicates that the balance temperature is changing.
Upon first power up, the instrument may take 2 hours to stabilize the balance at an elevated temperature. If the instrument is toggled off and back on, the new balance warmup period may be 20 minutes to 1
hour. All Computrac Moisture Analyzers are recommended to be left turned on when not in use, so the balance warmup should not affect throughput after the initial stabilization period.
The first ashing test after a power up may increase the balance temperature slightly, and the warmup message may be displayed again for up to 1 hour after the first test. The message generally goes away while the instrument is cooling down and before it is ready for the next test.
Generally, balance calibration and low moisture/solids/ash testing (<1%) should be delayed until the balance temperature stabilization is complete, as indicated by the temperature stable icon
