PARAMETER SETTING

The HAKKO 472D has the following parameters. Parameter settings can be adjusted.

1.

°

C or 

°

F temperature display selection.

2. Low temperature tolerance.
3. Display of room temperature compensation value (test mode)

Once parameter input mode has been entered, set the parameters in the order shown below. After all
the parameters have been set, normal operation will be resumed.

1.

°

C (Celsius) or

°

F (Fahrenheit)

Temperature Display

1. Turn off the power switch.
2. Insert the control card into the slot in the station.
3. Press and hold the 

 and 

 buttons simultaneously, then

turn on the power switch.

4. Continue  holding  down  the 

  and 

  buttons  until  the

display shows 

°

C (for Celsius) or 

°

F (for Fahrenheit).

5. When the display shows 

°

C or 

°

F, the station is in parameter

input mode.

6. Pressing  the 

  or 

  button  will  cause 

°

C  or 

°

F  to  be

displayed alternately.

7. Press the 

 button to select the scale. The low temperature

tolerance may now be entered.

2. Low temperature

tolerance
(Flashing of the
temperature display)

When the station enters the Low temperature tolerance setting
mode, the HUNDREDS digit will begin flashing. Enter and store
the  value  in  the  same  manner  as  described  in ‘Changing  the
temperature setting’.

Range of allowable heater error temperatures
For 

°

C: 30 – 150

°

C        For 

°

F: 60 – 300

°

F

If a temperature value outside this range is selected, the display
will again flash the HUNDREDS digit. If this happens, reenter a
correct temperature value.
After setting the low temperature tolerance value, the display will
show the room temperature compensation value (test mode).

3. Room Temperature

Compensation Value.

(Test Mode)

The display will not blink and the heater will not receive power.
The  room  temperature  compensation  value  is  the  measured
temperature of the nozzle. This function will be used later to
calibrate the nozzle temperature. (See “Recalibrate the Temper-
ature” on P.13)

No  inputs  are  made  here.  Press 

  to  complete  parameter

input. The  nozzle  temperature  setting  will  be  displayed  for  2
seconds, after which power will be supplied to the heater and
normal temperature control will begin.
