High Voltage Indicator
If connected to an energized line, the voltage on the
line can cause excess current to be forced through the
ST‑33Q� The ST‑33Q has a detection circuit that can
sense excess current and disconnect output from the
energized line� If the ST‑33Q senses excess current, a
warning message will appear on the screen, a warning
beep will sound, and the High Voltage LED will turn ON
(See Item 1, Figure 4)�

WARNING
If the High Voltage LED turns ON, turn OFF the ST‑33Q to
reset the detection current. After turning OFF the ST‑33Q,
carefully disconnect the ST‑33Q using high voltage
precautions. Do not use the transmitter to test for high
voltage. Connecting the ST‑33Q to external voltages
greater than 250 V will damage the unit.
High Temperature Warning
If the internal temperature of the ST‑33Q reaches 167°F
[67°C] or greater, a warning will appear on the screen
(See Figure 5)�
Figure 5 – High Temperature Warning
If the high temperature warning appears, the ST‑33Q will
automatically reduce power� If the internal temperature
reaches 176°F [80°C] the ST‑33Q will suspend output�
If the internal temperature reaches 176°F [80°C], turn
OFF the ST‑33Q to avoid damage and ensure a RIDGID
Independent Authorized Service Center services and
repairs the unit�
Pre‑Operation Inspection
WARNING
Before each use, inspect the ST‑33Q and correct any
problems to reduce the risk of serious injury from electrical
shock or other causes and prevent machine damage.
1� Confirm that the power is OFF, that any external
power and cords are disconnected, and that the
battery is removed� Inspect the cords, cables, and
connectors for damage or modification�
2� Clean any dirt, oil, or other contamination from the
ST‑33Q to aid in inspection and to prevent the unit
from slipping from your grip during transport or use�
3� Inspect the ST‑33Q for any broken, worn, missing,
misaligned or binding parts, or any other condition
which might prevent safe, normal operation�
