Outlet Circuit Testing
Unless a wiring error exists, the ST-1THD will show "Out" in the LED dis-
play. This indicates that the unit is calibrating itself prior to testing. After
this calibration is performed, the ST-1THD automatically enters into the out-
let circuit testing programming menu. The LED display cycles between the
menu heading, and the measurement every four seconds. Press and hold
the display advance button for one second to move to the menu. To enter
the submenu, press the display advance button for three seconds. To navi-
gate from measurement to measurement within the submenu, press the dis-
play advance button. While in the submenu, pressing and holding the dis-
play advance button for three seconds brings the unit back to the menu
structure.
1. Insert the ST-1THD into the receptacle
2. The LED display shows “Out” indicating self-calibration of the unit
3. The LED display cycles between “L_”, indicating that True RMS Line
Voltage is being measured, and the Line Voltage measurement every four
seconds.
4. Press and hold the display advance button for three seconds to access
the Line Voltage submenu.
5. The LED display alternates between “Hi”, indicating that the highest line
voltage is being measured, and the measurement every four seconds
6. Press the display advance button for one second to move to the next test
within the Line Voltage submenu.
7. Press and hold the display advance button for three seconds to return to
the main menu.
