drying. To ensure against over drying of samples, and
possible denaturing, it is recommended that the “Heater”
timer and the Radiant heat be set for only a portion of the total
run time (e.g., 50%-75% of total run time).
Preset Program Settings
The table below shows the values attributed to the preset
programs parameters.
*When the temperature is set to “no”, the heat time is
defaulted to “0.00” while executing the run.
**When the Run Type is set to TIME, the Vacuum level will
display “---” is shown until a run is started.
Exporting Live Run Data
The unit is equipped with a USB port to enable
communication with an external computer. The USB port is
located on the rear panel of the unit and is connected to a
computer via a standard USB type A to B cable.
Figure 2. USB Port location
When a run is ongoing, the unit exports the following
information via the USB port every minute.
•
The live temperature applied to the samples chamber
•
The remaining heat time for the run (“CCC” indicates
continuous heating)
•
The remaining or elapsed run time, depending on the run
type (manual or automatic)
•
The vacuum pressure in the samples chamber
The data are sent at a fixed baud rate of 115200 and are
comma-separated as shown in the format:
<temperature>,
<heat time>, <run time>, <vacuum pressure>
•
The temperature is represented as a 2-digit integer in °C
•
The heat time is expressed as a 3-digit integer in minutes
(or “CCC” for continuous heating)
•
The runtime is expressed as a 3-digit integer in minutes
•
The vacuum pressure is represented as a floating-point
number in Torr (or as “HPr” to represent a high pressure).

Note:
The preset programs are for convenience
only. Prior to use, users are advised to conduct a
risk assessment to confirm that the preset
program parameters meet the user’s application
specific needs and conditions. Users accept the
risks associated with using the preset programs.
CAUTION:
USB lead length less than 3 meters
shall be used to connect to the computer.
In case of a communication failure between the
monitoring program of the computer and the
product, user can re-establish the connection by
disconnecting and reconnecting the USB cable.
