CONTROLS AND ITEM DESCRIPTIONS

Numbers in (parenthesis) Reference Figure 1.
3.1 (1) AC Power Cord
The ST2200F-110 and ST2200C-110 units come with a 5 foot long 3 wire North
American power cord. Models ST2200F-220 and ST2200C-220 come with a 5
foot long 3 wire European power cord. Cord storage is provided on integral cord
wraps on rear of the unit.
3.2 (2) LCD Display
Easy to read .7 inch high 4-1/2 digit display. Resolution is switchable via internal
jumper. See the Maintenance Section 6.1 for details on setting resolution.
3.3 (3) FAIL MV/OHM Indicator
This indicator serves as a Pass/Fail indicator for both MV and Resistance
measurements. It is a bi-color LED which displays Green when unit under test is
acceptable or flashes Red when the unit is unacceptable. See the Specifications
section 2.0 or the Operation section 4.0 for details on the threshold limits.
3.4 (4) AC Convenience Outlet
This outlet is provided as a power source for the Unit under Test. All units come
with a North American receptacle and have power available anytime the ST2200
is plugged in. NOTE: 220 volt models supply 220vac at this connector. It is
recommended to use this outlet as power source for your unit whenever possible,
to achieve optimal results.
3.5 (5) Input Selector Switch
This switch selects between the ST2200 sensor and the Type K thermocouple
connector inputs. For soldering iron testing set Input Selector Switch to TIP TEST
position. Normal operation is the TIP TEST position. For Auxiliary type K
thermocouple probe input set Input Selector Switch to "AUX T/C - K" position.
Auxiliary probes may be used to test solder pots, wave solder baths, hot air guns or
ovens. See Accessories Section 5.0 for optional T/C probes for your specific need.
3.6 (6) Auxiliary Thermocouple Connector
This input connector is provided to interface optional Type K thermocouple probes
to the ST2200 unit. With the input selector switch set to AUX T/C-K the unit will
use the signal input to this connector as the source for measurements.
3.7 (7) ESD Protected Case
The ST2200 is designed for use in ESD protected areas. The case is grounded and
coated with chloride-free liquid anti-static protectant. The case has been tested for
triboelectric effect during normal operation. It will neither generate a charge nor
support a static electricity discharge.
