PID CONTROLLED SOLDERING STATION
RX-931AS
ST-77 Soldering Iron
Stand Included
Variable Temperature Setting and
Accurate Temperature Control
Temperature range from room temperature to
500°C. Digital display shows any difference
between tip and set temperature at a glance.
PID control provides precise and stable temperature
management. The temperature can
also be controlled using only P control when
required.
Tip Sensor to measure actual tip temperature
Accurate measurement and control of the tip
temperature using the tip sensor.
Keypad Lock Function
With security code from 001 to 999 there is no need
for tools or cards.
Alarm Function
A warning alarm and lamp inform you if the
set temperature goes outside the range.
The lamp can also be used as a safety
light to show when you are within the set
temperature range. There is also an alarm signal output terminal.
(Modification required)
Sleep Function (Patent Pending)
ACCURATE TEMPERATURE
CONTROL USING PID
The RX-931AS is a temperature controlled soldering station
with many features including PID temperature control, Keypad
Lock for safe temperature management and SLEEP MODE to
save energy and prevent static electricity.
Automatically reduces the tip temperature to the set temperature
when inactive for a set period.
MODE: Sleep Function ON-OFF Select
CT : Sleep start time setting (min.)
SST : Sleep temperature setting
DIF : Sleep start temperature range (˚C)
Setting of each parameter is possible.
ANTI
STATIC
Auto Tuning
Auto tuning determines the optimum PID value for the set temperature
when changing set temperature or replacing the heater or tip.
Calibration Function (Patent Pending)
Differences between tip thermometer and displayed temperature
are easily corrected by inputting the offset value.
Establishing Traceability
If you require calibration and issuance of the relevant certificates,
please contact your local distributor.
