Clear IDF/SDF Lines
When you press the Clear IDF/SDF Lines button on the Diagnostics screen, the IDF and SDF lines are cleared of any fluids.
Before running this diagnostic, place small waste cups at each IDF and SDF station under the nozzles and close the Front Cover
of the instrument.
Expert Mode
When Expert Mode is “ON,” all of the question screens in the IDF/SDF and TDF procedures are bypassed except for the
“Check pH manually?” and “Filter minutes OK?” screens. See the “Productivity Enhancement” section of this manual for more
information about Expert Mode.
You must be careful while in Expert Mode or you could cause problems!
The IDF/SDF and TDF analyses both start filling the SDF bag with EtOH about an
hour after the IDF procedure starts. Therefore, if you start an IDF procedure, and
wait more than an hour to properly install your SDF bags, the instrument will
deliver EtOH to the empty bottom stations, wasting EtOH, and ruining a run.
Service Mode
When you press the Service Mode button on the Diagnostics screen, the following screen will be displayed.
Service Mode – Volume Calibration
Refer to the “QC / Calibration Checks” section of this manual for details about this diagnostic.
Service Mode – Temperature Sensor Corrections
Refer to the “QC / Calibration Checks” section of this manual for details about this diagnostic.
Service Mode – Bypass Amylase Phase Initial Heat-up
For digestions to occur at the correct temperature for the correct amount of time, the instrument’s computer waits for the
heating paddles to heat up to the target temperature before starting the digestion timer. When this button displays the word
“YES,” the instrument’s computer will start the digestion timer without waiting for the heating paddles to reach the target
temperature.
Only use this option when demonstrating or troubleshooting the instrument. If the
bypass is enabled, a warning screen will be displayed at the start of a new run. At
that time you can tell the computer to disable the bypass and return to the standard
operating mode of waiting for the heating paddles to reach the target temperature
before starting the digestion timer.
