1. Notes:
1. The grounding column on the test plate is convenient for users
to connect with crocodile clips, and its interior is connected to
the simulated ground, please do not loosen it, so as not to have
poor grounding.
2. The temperature sensor is very thin, only ф0.2 in diameter, and
must be very careful, if too much force is used, it will cause a
break.
3. The test point of the temperature sensor is specially treated, but
frequent testing will cause it to wear, so once there is wear, it
should be replaced immediately to ensure the accuracy of the
test.
4. When there is flux at the terminal, it should be wiped clean
with an alcohol-stained cloth, and it cannot be cleaned with
paint thinners or benzene.
5. Before testing, new solder is applied to the soldering iron head,
which is necessary to ensure good contact between the
soldering iron tip, the temperature sensor and the test plate.
6. During the test, please do not touch the soldering iron tip to the
non-stiff steel platform under the test point, so as not to cause
measurement errors.
7. The overflow flag is -1 or 1, and during the test voltage and
resistance, the soldering iron tip and the test plate do not
contact, at which point a numerical value shows that this is
normal.
8. In the process of testing voltage and resistance, the AC power
source required to be used must have a ground wire.
9. When testing voltage and resistance, if the data exceeds the
specified value, check whether the tightening screw of the
soldering iron tip is loose, tighten it, and then retest.
The part name
1. With R2-R1, the resistance R=R2-R1 between the soldering
tip and ground can be obtained.
(5) Overflow display
2. The overflow code is 1, which indicates that the sensor is not
connected when measuring the temperature of the soldering
iron, and when measuring voltage and resistance, the soldering
iron tip is not in contact with the test plate or that the ground
wire inside the soldering iron is broken.
3. The overflow code is -1, possibly because the red or blue
termination of the temperature sensor is reversed or the
measured temperature is below 0ºC
Ground wire
The grounding wire is the connection between the soldering iron
grounding wire and the temperature tester, which is used to measure
the voltage and resistance of the soldering iron tip to ground.
Maintenance & Calibration
1. If there is solder at the terminals, it can be wiped off with a
soft cloth dipped in alcohol, not with diluents or benzene.
2. Repeated tests can wear out the sensor, if you need
accurate measurements, replace the sensor with a new one.
