METER
The meter is the main portion of the STM system. The
front face of the meter has all the inputs and outputs. The
screen displays the data that is necessary to use the STM.
The three buttons below the display screen guide you
through the programming menus as described on pages
16 - 26 of this manual.
The actuator plugs into the upper left receptacle and the
sensor plugs into the lower left receptacle. The RS-232
port on the upper right is for a computer or printer. The
power receptacle on the lower right is for power and
recharging the battery.
To recharge the battery inside the meter, plug the
transformer into a 120 volt duplex outlet. A solid green
light indicates that the battery is charging. A flashing green
light indicates when charging is done. When the battery is
low, the display indicates “Low Battery” and allows 5 - 10
minutes of further testing.
To provide a longer life for the battery, completely discharge
the battery before recharging. This can be accomplished
in the MM TEST FUNCTION AND SERVICE section on page
21.
SENSOR
The sensor is the component that has two magnets; one
on the cable that attaches to the reciprocating machine
component (ram), and one that is attached to the bottom
of the sensor enclosure to hold it in position. The cord and
plug attach to the meter.
ACTUATOR
The actuator is a hand-held component that either
releases or actuates a button or other initiating means on
a machine. It also operates the flag which can interrupt
a presence sensing device. The cord and plug attach to
the meter.
