Operation
26. Using the CH SELECT Key, select each Active Channel in sequence, making it the Current Channel
(temperature information displayed on Digital Readout). Using the procedures described in previous
steps 9 thru 17 and step 25 as a reference, enter and store desired Tip Temperature information into
system memory. Refer to the "Tip & Temperature Selection System" booklet sent with your unit and the
Tip & Temperature Selection section of this manual for more detailed information on selection of the
proper tip, handpiece and temperature options for your particular application.
The MBT 250 systems embody a "Dynamic Offset" feature which automatically
adjusts the stored TIP OFFSET CONSTANT (stored value is for Tip Offset at 371°C
or 700°F) for any Set Tip Temperature established by the operator. This ensures
the maintenance of true, accurate Tip Temperatures. Simply stated, any operating
Tip Temperature displayed on the digital readout will be correct.
Always set the appropriate TIP OFFSET CONSTANT for the selected handpiece/
tip combination (listed in the shaded area on the Tip & Temperature Selection
System booklet charts) before entering the desired Set Tip Temperature. The Set
Tip Temperature + the Dynamically Adjusted Tip Offset value (usually different
from the entered TIP OFFSET CONSTANT) cannot exceed 489°C (912°F). If this
limit is exceeded, the system will automatically lower the maximum possible Set
(and Operating) Tip Temperature accordingly.
27. If the Key Lock option is present (from step 3), turn
the Key to the "Lock" position. Notice that no
changes in Set Tip Temperature or Tip Offset
Constants are possible with the Key Lock in this
position thereby preventing any unauthorized
alteration of settings.
