TESTING THE HEATING ELEMENT
To test if the heating element is in working condition:
Cool down assembly to room temperature before continuing the tests
below:
1. Follow
“disassembling the hand piece”
guide.
2.
Do the following tests on the hand piece PCB board:
◆
Resistance value of heating element 18 — 23
Ω
◆
Resistance value of sensor 2.3 — 3.5
Ω
◆
After testing check results with the following:
◆
If the resistance value is not as stated above replace the heating
element.
◆
If a 0
Ω
or infinite resistances are measured check for shorts or
open circuits.
◆
Itermittent readings can also be caused by cold solder double
check solder points if the heating element has recently been
replaced.

OPERATING INSTRUCTIONS
1.
Follow procedures shown in the “Assembly Instructions”.
2.
Turn on the unit.
3.
Turning the control knob clockwise increases the desired (SET)
temperature settings, while turning the knob counter-clockwise
decreases the desired (SET) temperature settings.
4.
When the heater lamp blinks on and off then it means that the tip
temperature has reached the set temperature and is ready for use.
