Your Triad Freeze Dry System has been carefully calibrated and tested before
shipping, however under certain circumstances it may be necessary to adjust
the calibration of the vacuum display or to reset factory settings. These
adjustments may be necessary if the freeze dry system requires service.
An offset may be added to the vacuum display. Use an accurate traceable
reference to compare the readings.
Vacuum offset may be varied ±0.010 mBar in 0.001 mBar increments.
Modifying the Display
To enter an offset or to restore all factory settings, perform the following
steps:
Press the DISPLAY button until the SET UP INDICATOR is lit.
Press and hold DISPLAY button for 10 seconds.
The display will first show the screen used for setting Auto mode
parameters and then will show:
If you want to restore all factory settings hold ENTER approximately 5
seconds.
This will reset:
Vacuum units to mBar
Vacuum offset to 0 mBar
Temperature units to °C
Refrigeration service hours to 0
Vacuum total hour to 0
Vacuum service hour to 0
Refrigeration total hours to 0
RS232 transmission rate to 10 seconds
At the completion of Master Reset, the display will return to the monitor
mode.
