Testing The Heating Element - aoyue Int936A Instruction Manual

TROUBLESHOOTING CONNECTIONS
Follow the following direction to test for hand piece cord
faults:
Test 1: Rendering physical strain to the cord
1. Turn on the unit.
2. Set temperature to 480 °C.
3. Bend and straiten the entire length of the cord bit by bit. The
heater lamp should always be lit while doing so. If the heater lamp
becomes intermittent the cord is faulty and should be replaced.
Note: the Heater lamp will blink if the temperature of the
soldering iron tip has reached the set temperature i.e.
480°C. this is not an indication of a faulty cord.
Test 2: Resistance test
1. Follow the steps in disassembling the hand piece .
2. Test for continuity between the following pins and colored wires at
the hand piece PCB, all tests should register 0 to 2 Ω.
3. If any of the above mentioned combination does not register 0 Ω
the cord is faulty and should be replaced.
4. See our "replacing the soldering iron cord"guide.

To test if the heating element is in working condition:
Cool down assembly to room temperature before continuing the tests
below:
"disassembling the hand piece"
1. Follow
2. Do the following tests on the hand piece PCB board:
Resistance value of heating element (RED) 2.5 — 3.5 Ω
◆
(Int936/936A)
Resistance value of sensor (blue) 43 – 58 Ω (936A)
◆
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.
