ACTIVATION OF LOCKOUT FEATURE
1. Set the digital display to the desired tip temperature.
2. Momentarily touch the Lockout Pencil (PW50) to the ESD symbol on the front panel. The decimal point on the MSD (Most
Significant Digit) will blink if the Lockout Pencil is held against the touch panel. Remove the Lockout Pencil from the ESD
Symbol and the single decimal point in the MSD (Most Significant Digit) will be illuminated, indicating that the station has
been Locked. The lockout set temperature will be displayed for 3 seconds before switching to the actual tip tempera-
ture.
Adjusting the temperature set knob will temporarily display the Set point of the station, even though the unit will
not
change the temperature setting, when in the Lockout mode.
3. Reverse the lockout by momentarily touching the Lockout Pencil to the ESD symbol. Remove the Lockout Pencil slowly
and
the temperature set knob will function as normal. The single decimal point in the MSD (Most Significant Digit) will
now be
Off.
Note:
If the temperature set knob is adjusted during the Lockout mode, the temperature setting will display the
current Position/Setting of the temperature set pot, when the Lockout function is removed.
TIP TEMPERATURE OFFSET PROCEDURE
1. Monitor the tip temperature using the K111, Type K Thermocoupled Tip temperature test kits. (see Replacement Parts
and
Accessories Section)
2. Set the digital display to the desired tip temperature and allow the tip temperature to stabilize (as indicated by the Read
mode).
