Temperature Unit Function (
U)
This function serves to set the desired temperature unit (°C or °F) via the (+) and (-) keys.
Note
:
If the station is protected by a password, the parameters only can be
changed by entering the correct password. (see chapter 5.3.7 Password
Function)
5.3.3
Standby Function (
S
)
This function switches the soldering station to a state of readiness if it has not been used
over a preset period of time. The purpose of this function is to protect the soldering tip
and to reduce energy consumption.
In standby, the soldering tip temperature is lowered
to 200°C (390°F). The standby time is set in minute increments. The setting range is
0 – 60
min, with an input of 0 disabling the standby function.
When the station enters standby mode, the display starts to flash. When an arbitrary key
is pressed, the station returns to the normal mode. For soldering irons with SENSOTRON
-
IC, cleaning the tip on the dry sponge can also enforce the switch over to normal mode.
By wiping the soldering tip, the station recognizes an abrupt temperature reduction and
switches back to normal mode. This function works best for certain soldering tips of all
mass. Heavy mass tips will often not be sufficiently cooled during cleaning to reset the
station into normal mode.
You should switch off the standby function when working with small soldering spots.
In such cases, the heat emission at the soldering tip may be too low for soldering to be
registered. The
station would then undesirably lower the soldering temperature to the
standby temperature.
Restrictions of the standby function:
The standby function is not restricted with the
TECH TOOL
, the
X-TOOL
and the POWER
TOOL
.
On the other hand, the time characteristics of the MICRO TOOL and the CHIP TOOL
do not allow reliable recognition of an operation. For this reason, with these two tools
the soldering station always switches to standby mode after the standby time has passed.
