5-3 TEMPERATURE CALIBRATION
(Tip thermometer required)
A. RX-701AS only
1.
Set the desired temperature using the
Temperature Setting Knob.
2.
While measuring the tip temperature with a tip
thermometer, adjust the CAL (Calibration Screw)
with Flat-head screwdriver to bring the mea-
sured temperature to the desired temperature
scale. The tip temperature increases when the
CAL is turned clockwise, and it decreases when
the CAL is turned counter-clockwise.
B. RX-711AS only
1.
Switch the Temperature Display Changeover
Switch (at the left of the front panel) to SET.
2.
Set the desired temperature using the
Temperature Setting Knob.
3.
While measuring the tip temperature with a tip
thermometer, adjust the CAL (Calibration Screw)
with Flat-head screwdriver to bring the mea-
sured temperature to the desired temperature
scale. The tip temperature increases when the CAL
is turned clockwise, and it decreases when the
CAL is turned counter-clockwise.
5.
Desolder the 3 locations of pins for the
heater. Remove the heater from the
PCB.
6.
Solder the new heater to the PCB. Cut out the extra heater lead wire 3mm
or less from the PCB.
7.
Next, about the PCB slot orienta-
tion. The PCB slots are offset from
center. The longer arc should be up.
The shorter arc should be down. The
Earth Pin should be down.
8.
Reassemble, reversing these steps.
