The internal circuitry of the ST2200 is protected against static discharge that may
be applied to the sensor during test of soldering irons or when the auxiliary
thermocouple connector is used.
3.8 (8) Sensor
ST2200 Soldering Iron Testers are shipped with Model WST-02B heavy duty bead
sensor. Sensors with bonnets are designed to aid in the positioning of the iron tip.
Sensors plug in for ease of maintenance or replacement. See Accessories Section
5.0 for optional sensors.
3.9 (9) Wrist Strap Test
This area provides convenient go/no-go testing of wrist straps. It consists of a
jack for the wrist strap to plug in to, a grounded acorn nut for the operator to
touch and a bi-colored LED for test result indication.
3.10 (10) Power On-Off / Function Selector Switch
Power is provided to the unit anytime the Function Selector Switch is in any
position other than OFF. In normal operation with the Function Selector Switch
in the TEMPERATURE position, the display will indicate ambient room
temperature. With the Function Selector Switch set to either MILLIVOLT
position or RESISTANCE position the display will indicate "1---" until the
soldering iron tip is placed in contact with the sensor.
3.11 (11) Voltage Spike Indicator
This indicator serves as an indicator for the detection of voltage spikes detected
during MILLIVOLT testing. It is a bi-color LED which displays Green when no
spike is present and flashes Red when the spike is detected. See the
Specifications section 2.0 or the Operation section 4.0 for details on the spike
threshold limits.
