Soldering StationThis soldering iron tool is controlled automatically by the micro-processor. The digital control electronics, high-quality sensor, and heat exchange system guarantees precise temperature control at the soldering tip. The highest degree of temperature precision and optimal dynamic thermal behavior under load conditions is obtained by the quick and accurate recording of the measured values in a closed control circuit. This design works especially well with lead-free production techniques.

Operating InstructionPlace the soldering iron in the stand. Push the 5-pin plug on the end of the soldering iron cord into the 5-pin socket on the right side of the station and turn clockwise to tighten the plug nut. Connect the station, with the included AC power cord, to a 120 VAC wall socket and turn the soldering station on using the switch in the rear. A self-test is carried out in which all display elements will beswitchedonbriefly.Theelectronicsystemwillautomaticallyturnontothesettemperatureanddisplaythecurrentvalue.

Display and temperature setting1. Display for actual temperature of the soldering tip.2. Display for set temperature. Turn the “UP”- “DOWN”

knob clockwise to increase temperature and counter-clockwise to decrease temperature.

3. °C/°F display: Change the temperature display from °C to °F by pressing “UP”- “DOWN” knob, then the electronic system will display the actual temperature and setting temperature in °C or °F.

4. When the actual temperature on the soldering tip is less than the set value, “HEAT ON” will display when the tip is heating up to maintain the desired temperature.

5. When the absolute offset is more than ±10° C between the set value and the actual temperature on the soldering tip, “WAIT” will display. This means that the temperature control system detects a non-stable situation. Pause a moment until “WAIT” disappears.

6. When “ERROR” displays, there may be an issue with the temperature control system, or the soldering iron is not connected to the station correctly.

Diodes and Continuity Measurement (see figure 5) WarningTo avoid damage to the meter or to the device under test, disconnect circuit power and discharge all the high-voltage capacitors before diodes.Use the diode test to check diodes, transistors, and other semiconductor devices. The diodes test sends a current through the semiconductor junction, and then measures the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V.To test a diode out of a circuit, connect the meter as follows:1. InserttheredtestleadintotheVΩmAterminalandthe

black test lead into the COM terminal.2. Set the knob to Diodes.3. For forward voltage drop readings on any semiconductor

component, place the red test lead on the component’s anode and place the black test lead on the component’s cathode.

4. The measured value shows on the display.Note1. In a circuit, a good diode still produces a forward voltage

readingof0.5Vto0.8V;however,thereversevoltagedropreading can vary depending on the resistance of other pathways between the probe tips.

2. Connect the test leads to the proper terminals as outlined above to avoid error display.

3. The LCD will display “1” indicating open-circuit for wrong connection. The unit of diode is Volt (V), displaying the positive-connection voltage-drop value.

4. When diode testing has been completed, disconnect the connection between the testing leads and the circuit test.
