VACUUM
1. Executing an AUTO “VACUUM” RUN type:
(GREEN light ON above vacuum).
a) Press “RUN TYPE” to select “VACUUM” RUN.
b) Using “SELECT” button and the up/down keys set “VACUUM”
pressure at which the run should end. (Ex. 500 Microns), would be
entered as 00.5 torr.
c) Close cover.
d) Press “AUTO RUN” button to start the run. The cover locks and the
rotor starts turning. The display will count up in 1 minute intervals
and the decimal point blinks. The heat time will count down in
1 minute intervals. The temperature rises in 1
°C increments from
35 °C to set temperature. The vacuum pressure is declining from
Hpr. (Atmospheric Pressure), after both SAV valves actuate,
allowing vacuum into the chamber.
e) Press R/C for radiant cover heat. Press at any time to turn OFF
and ON.
f) Once the unit senses the set vacuum pressure in the chamber has
been achieved (< 500 Microns) it ends the run and the display
will show “End”, the SAV valves will click, also allowing air to bleed
into the chamber.
g) After the rotor stops spinning, the cover unlocks and the display
reverts to last parameters.
h) Open the cover and remove samples.
GENERAL
: During the run, display shows actual parameters.
To check set parameters press “VIEW” button and “SELECT”.
The display will revert temporarily to set points.
