Definitions
Please read and become familiar with the definitions of each of the following terms that are used
repeatedly in the following operational procedures.
Auto-Off: Safety feature that turns power off (10-90 minutes, settable in 10 minute increments)
after the system has entered Temperature Setback.
Normal Operation: Normal operating mode of the system in which the Operating Tip
Temperature is displayed.
Set Tip Temperature: The operator selected idle tip temperature entered into the system
memory.
Set-Up Mode: Mode of operation in which the operator can quickly and easily adjust the system
parameters (e.g., temperature limits, password, setback time).
Temperature Adjust Mode: Mode of operation where the Set Tip Temperature may be
adjusted.
Temperature Display Impedance (TDI) Mode: Stabilizes the tip temperature shown on the LED
Display by ignoring minor temperature fluctuations. Displayed changes in temperature are
delayed (impeded) for two seconds when a load is applied to the tip. Two seconds after the load
is removed, the displayed temperature will begin rising to set temperature. Particularly useful in a
production environment for monitoring of set temperatures, since under most production
circumstances the temperature will not deviate.
Temperature Setback: System feature that will independently set back the Set Tip Temperature
to 177°C (350°F) after a user selected period of handpiece inactivity (10 to 90 minutes, settable in
10 minute increments). This feature is enabled (or disabled) in the Set-Up Mode.
Tip Offset Constant: Specific value for a given handpiece/tip combination upon which the
system automatically calculates the correct Tip Temperature Offset at any entered Set Tip
Temperature. This value is the temperature loss (Tip Temperature Offset) at 371°C (700°F) and
is set in the Set-Up Mode. A value of 0-115°C (0-240°F) may be entered in the Set-Up Mode.
Password: The Password feature of the ST 45 or ST 55 system will prevent unauthorized
alteration of stored system temperature parameters and feature settings (refer to Table I, “Factory
Settings”). If a Password has been installed, the LED Display will display an instruction to enter
the Password (a 5 key sequence of the keys on the system front panel) when a setting change is
attempted.
