Helpful Hints
• As a general guideline, using lower frequencies with
the least amount of current and a clear signal will
produce the best locating results. Start with a low
frequency if tracing long distances or when receiving
too much bleed-over onto other utilities.
• The ST-33Q+ will generate frequencies as low as
128 Hz in Direct Connect Mode. The ST-33Q+ will
allow custom frequencies as low as 10 Hz.
• In general, 8 kHz offers a good starting point when
using the ST-33Q+ in Direct Connect Mode. When
using Inductive Mode, 33 kHz will likely be the best
starting frequency.
• The ST-33Q+ will generate frequencies as high as
490 kHz (95 kHz in the European version). High fre-
quency signals are especially valuable when tracing
a line with interruption (such as a gasket or dam-
aged insulation). Unlike low frequency signals, high
frequency signals can "jump" some barriers and con-
tinue without appreciable dissipation.
• When using Inductive Clamp Mode, use higher fre-
quencies since the signal must overcome additional
resistance.
