Operation
Operation of the Obtura III MAX has been designed to be intuitive, however, to fully realize the extent of the instrument
and its many features, please read this entire section.
There are four (4) tactile switches on the front of the Obtura III MAX and an LCD display. The functions of the
four switches are: Power On/Off , Temperature Up, Temperature Down and Temperature Memory (as shown
in the “Quick Start Guide” section). When the Obtura III MAX is activated, the 3-digit display will indicate
the current operating temperature in degrees centigrade, and any memory presets desired. Description of each
button follows:
Press the Power On/Off button to activate the Obtura III MAX. The display will show the last used set-
------
point temperature. After 5-seconds, the actual heater temperature will be displayed, heating up to the
------
set-point. Press the Power button again to toggle off.
With the unit on, press the Temperature Up (+) button to increase the set-point temperature in single degree
------
increments. Press the Temperature Down (-) button to reduce the set-point temperature, also in one degree increments.
The Temperature Memory button retrieves preset memory set-points. A quick press of this button displays the
------
letter “M” and the preset position number. The temperature associated with the memory setting is displayed on the
------
three-digit display. To set the unit to this temperature, no other action is required, and after 5 seconds, it will now
-----
be the new set-point temperature and will be indicated on the unit screen. To access another memory position,
------
again press the Temperature Memory button to display the desired memory setting, and again within 5-seconds,
------
the unit will set to the next positioned temperature.
To reset a memory location, press the Temperature Memory button until the preset position number you
------
want to modify is shown. Then, within 5 seconds, adjust the preset temperature with the Temperature -------
------
Up (+) and Temperature Down (-) buttons. The memory and the display are now set to the new temperature.
------
After 5 more seconds, with no button pressed, the Obtura III MAX display will change from the previously
------
set temperature to the new set-point temperature. Note: preset memories are saved even during power failure.
The Obtura III MAX requires approximately 120 seconds to heat from ambient room temperature of about 25°C, to
maximum operating temperature of 200°C.
