7.2 Operating the Controls of the xxsealer
When the unit is switched on, it recalls the last sealing operation settings
and the displays the sealing temperature or time (depending on the
display mode), and automatically restores the heater on/off state.
Pressing the
MODE
button toggles the LED display between the plate
heater
Temperature
set-point in degrees centigrade and the seal
Timer
setting in seconds.
The sealing temperature is set by pressing the
MODE
button to illuminate
the
Temperature
LED (
) then using the
UP
and
DOWN
buttons to
set the temperature in the range 125 to 200 ºC in 1ºC steps.
Likewise, the sealing time is set by pressing the
MODE
button to illuminate
the
Timer
LED (
) then using the
UP
and
DOWN
buttons to set the
time in the range 1 to 9 seconds in 0.5 second steps.
Pressing the
HEATER
button toggles the plate heater between on and off.
When the
Heater
LED is flashing, the heater is on and the plate is warming
up, which will normally take about 10 minutes.
Once the
Heater
is on the LED display shows the current temperature or
sealing time set-point (depending on the mode).
When the heater plate is up to temperature (within 2ºC of the set-point)
the
Heater
LED will remain constantly on, and the
xxsealer
is ready to
begin sealing.
The operator may set a precise temperature and seal time for the sealing
operation. Sealing is initiated by pulling the handle down, which raises the
sample plate into contact with the heater plate. The unit detects when the
sample plate is correctly positioned and starts a countdown timer. When
the display reads zero, the operator moves the handle back to its upmost
position, which moves the sample plate away from the heater plate. The
sample plate is then manually removed for storage or further processing.
