Battery Saver Mode
This allows the user to limit the power output of the ST-510
line transmitter to approximately 1 watt in order to prolong
the life of the batteries. In many cases 1 watt of power is
all that is needed. Using the unit with up to 10 watts allows
for more power to be used, but consumes the batteries
much faster. Battery Saver is off by default.
Figure 27 – Battery Saver and Auto-Off Options
Auto Shut Off Adjustment
Check this box to have an automatic shut OFF of the
transmitter. When checked, using the select key, the ST-
510 will automatically shutdown to help conserve batter-
ies. Shutdown time using this feature varies with current
draw. The approximate values are:
8 hrs 25mA output or less
4 hrs 50-100mA
2 hrs 200-400mA
1hr >400mA
This feature prevents the batteries from running down if
the unit is inadvertently left on. Auto Shutoff is on by de-
fault. (See Figure 27).
Figure 22 – Current Selected
When a current level is chosen, the transmitter will adjust
the voltage to try and produce the selected current and
lock it in. If the transmitter cannot produce the current se-
lected, it will adjust down to the next level.
The transmitter’s maximum current output depends on
the amount of resistance in the circuit. When the trans-
mitter is putting out the maximum current possible for in-
ternal and external conditions, MAX will be displayed in
place of the current strength number.
Figure 23 – MAX Current
MAX will also appear if the power output of the trans-
mitter is at its allowable limit.
When the current drops below 5 mA, “LO” will appear in-
stead of a number.
Figure 24 – LO Current
If the desired current output cannot be produced, the volt-
age and ohms (resistance) readings can give useful in-
formation. For example, if the transmitter is putting out a
high voltage, the resistance of the circuit is probably
too high. If the voltage is lower (30V max) and the ohms
(resistance) reading is also low, the line transmitter may
be constrained by power restrictions. (See FCC limits in-
formation on page 4.)
If the transmitter is showing low or no
current, the signal may be too low to be detected by
the receiver locator and inadequate for tracing.
