Calibration - Pace ST 65 Operation & Maintenance Manual

Calibration

The ST 65 system is tested for temperature accuracy at the factory and can be
checked for calibration according to PACE requirements. Also, a temperature setting
normally used by the operator can be adjusted to the precise temperature indicated
on the Dial/Display. No internal adjustments can be made to the power supply. To
verify calibration of the power supply, perform the following procedure.
1. Install a tip with an attached thermocouple
wire into the handpiece connected to the
system. Tips with K type thermocouples
are available from PACE; use part number
7021-0004-P1 when ordering.
2. Connect the thermocouple assembly to a PACE Process Monitor (part
number 8001-0077 or 8001-0078) or appropriate temperature meter.
3. When set fully counterclockwise,the pointer of the Variable Temperature
Control knob will align to the Calibration Mark as shown. With the
system turned on, adjust the Variable Temperature Control to obtain a
stable tip temperature of 300°C (for PACE factory specifications) or the
temperature setting normally used by the operator.
If the temperature displayed on the Process Monitor (or temperature meter) is
within ±15°C (27°F), perform steps 4 thru 6 to obtain a precise reading. If the
temperature is off by more than ±15°C, the handpiece may require
maintenance. Recheck the temperature using a second handpiece.
4. Carefully lock the Variable Temperature Control in position by tightening
the inner set screw (closest to front panel).
5. Loosen the outer set screw on the Variable
Temperature Control knob (furtherest from
front panel) using the Temp. Locking Key (hex
key) supplied with the system. Position the
knob with the pointer aligned to match the
temperature indicated on the Process Monitor
(or temperature meter). Secure the knob in
position by tightening the outer set screw.
6. Loosen the inner set screw to unlock the
Variable Temperature control if adjustment of
operating tip temperature is desired.
