DIGITAL CALIBRATION
I.UtilizingtheDesolderingGunDigitalTemperatureCalibration
1. TurnontheDesolderinggunfunctionswitch.
2. Set to appropriate temperatureyou wantto calibrate. Place the
tipofthedesolderinggunonanexternaltemperaturemeter.
3. Thereadingsontheexternaltemperaturesensorshouldbemore
orlessequaltothedisplayedtemperature.
4. Iftherearelargediscrepancyinthetemperaturereadingwecan
recalibrate  the temperature setting. First write down the set
temperature of the soldering iron and the actual temperature
readingfromtheexternaltemperaturemeter.
Forexample:
Settemperature=300
externaltemperature=350
5. TurnofftheSolderingIronFunctionswitch(“14”fromthecontrol
panel).EnsurethattheDesolderingGunFunctionswitchisinthe
offposition(“12”fromthecontrolpanel).
6. PressandholdtheUP buttonoftheSolderingIronTemperature
Adjustmentbutton(“4”fromthecontrolpanel).
7. TheDesolderingGunTemperatureDisplay (“14”fromthecontrol
panel).Willswitchtofourzeros“000”indicatingitisnowinthe
desoldering gun temperature calibration mode. Release the UP
buttonoftheSolderingIronTemperatureAdjustmentbutton(“4”
fromthecontrolpanel).
8. Use the Desoldering Gun Temperature Adjustment buttons (“5”
from the control panel)  to increase or decrease the calibration
values.Inourexamplethesettemperatureis300buttheactual
temperature is 350, There is a difference of 50 degrees. Press
theupbuttonuntilwereach“050”.
9. Confirmthe changebypressingandholdingthe“UP” buttonof

OPERATING GUIDELINES
4. Adjust the air flow level using the AIR PRESSURE ADJUSTMENT
BUTTONS(“3”fromthecontrolpanel).
5. Adjust the hot air gun air temperature using the HOT AIR GUN
TEMPERATURE ADJUSTMENT BUTTONS (“2” from the control
panel). The prefix of the display for Hot Air Gun Temperature will
change from “C” to “c” indicating that air temperature is being
adjusted. It will return to “C” indicating actual temperature is
displayed.
6. Reworking task can be started 1 minute after the desired hot air
temperature and airflow level are reached, as also indicated from
displaypanel“18”.
7. When reworking is complete, return the Hot Air Gun to its holder
butDONOTimmediatelyturnoffthemainpowerswitch.
8. DeactivatetheHotAirGunActivationbuttonfirstinordertoactivate
theautocoolingprocess.Thesystemwillstarttoblowair(atroom
temperature)atafastratetoreduceheatfromthehotairgunand
bring down the temperature to a reasonable safe level of 90°C.
Duringthistime,theairflowdisplaywillalsochange“cool”while
temperatureisgraduallydecreasing.Oncethetemperaturedropsto
approximately 90°C thesystemwillhaltanddisplay“OFF”onthe
panel.Itisnowsafetoswitchoffthemainpowerswitch.
9. TurnOFFthemainpowerswitch.
10. Unplugthedevicefromthemainpowersource.
IMPORTANT:Whenadjustingtheairtempe rature,itisstrongly
advisedtoinitiallyincrease theairflowlevelinorderto manage
the system temperature. This is to protect the heating element
insidethehandlefromexcessiveheatandavoidthepossibilityof
subjectingadjacentcomponentstothermalshock.
