Set-Up Mode & Calibration - Metcal QX2 Manuel D'utilisation

SET-UP MODE & CALIBRATION
The Set-up mode will allow you to change some settings of the QX2 system. To enter
this mode, turn off the main power, hold down the +/- keys simultaneously and turn
the main power on.
The LCD will display a prompt to enter an Access Code. Use the +/- buttons to
change the number of your code. The default code from the factory is "000". Push the
Start/Stop Button to submit the code and enter the Set-up Mode.
A form for you to write down your code is provided with the unit. It also tells you
the universal access code number that will always work in case you forget your code.
You may wish to store it separately.
Once you are in the Set-up mode you will have the menu options listed below.
Cycles: Displays the number of Remove and Attach cycles that the system has run.
Hours: Displays the cumulative run time.
Temp Units: The default setting for this is ˚C. The set up mode offers you the option
of changing this to ˚F by pushing the + or - button.
Setpoint: The default temperature is set to 350˚C. This is the temperature of the air
exiting the heater. If you wish to adjust this set point, you can hold down the +/-
keys to set the desired temperature. The setpoint can be adjusted between 250˚C
and 450˚C. Unless you have unusual process conditions, it should not be necessary
to change the setpoint.
Display: The default setting is for the controller to display the temperature of the air
exiting the heater. By pushing the + or - button, you can change this setting to have
the controller display the temperature from the auxiliary thermocouple port.
New Code: Allows you to change the Access Code used to enter the Set-Up mode.
Use +/- to change the code.
Calibrate: Allows you to enter the calibration mode. Use + or - to change to "Y" and
then push the Start/Stop Button. The calibration procedure requires a Thermocouple
Calibrator. Please contact Metcal Customer Care for assistance.
Set Defaults: Allows you to return all settings to the factory defaults. The following
are the factory settings:
Access Code: 000
Temp Units: ˚C
Setpoint: 350˚C
Display: Internal
Calibrate: none (clears any new calibration settings)
For all the menu options, pushing the Start/Stop Button enters your changes and
cycles to the next option. To exit the Set-up mode, turn the main power off.

BOARD HOLDER
OVERVIEW
The board holder provides a self-centering mechanism for holding a PCB from
50 mm x 50 mm to 360 mm x 460 mm in size horizontally at a distance of 120 mm
from the workbench surface.
SET-UP
Place the board holder on a workbench with a level surface. The unit is now
ready for use.
OPERATION
Rotate the wheel of the board holder assembly clockwise or counterclockwise to
move the clamp rail in or out to accommodate the size of the PCB to be reworked
Position the PCB between the clamps. The clamps may be adjusted by sliding them
along the rails, to avoid interference with any components on the edge of the PCB.
They should support each corner equally if possible. Tighten the clamps gently by
rotating the wheel. Do not overtighten: the PCB may break or the clamps may be
damaged. The clamps will flex to accommodate thermal expansion of the PCB during
the rework process.
