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.
