GUARDIAN PLUS
CM-1701 USER MANUAL
DESCRIPTION
This Guardian PLUS™- CM-1701 is a single person and workstation continuous monitor. The first channel monitors
the path of the ground to the operator wearing a single wire wrist strap. The other channel monitors the path of the
ground to the ESD work surface (Table Mat). When using the monitor, any breaking of the path to earth/electrical
ground of operator wearing a wrist strap or breaking the path to earth/electrical ground the work surface (Table Mat)
would be known at once because of the blinking RED LED and piezo buzzer. The operator or work surface (Table
Mat) is always connected to ground automatically even when the on/off switch is in the off state. The Guardian Plus
CM-1701 thus becomes a common point ground even when the CT-1701 is in the off state.
IMPORTANT
Always connect the Guardian Plus CM-1701 to earth ground.
INSTALLATION
1.
Connect this equipment to the earth/electrical (ground) of the building. This equipment comes with a grounding
wire. One end of the ground wire is connected to the back of the CM-1700. The other end is connected to the
earth/electrical ground. (FIGURE 1.). Always check that the electrical ground is correctly attached.
2.
Connect the CM-1701 to the ESD work surface (Table Mat) by using a cord with banana plug (Not provided) See
(FIGURE 1.).
3.
Connect the ESD work surface (Table Mat) to the earth/electrical ground the mat must have a conductive layer.
See (FIGURE 1.).
4.
Connect the 9VDC power adaptor to the back of the equipment. The other end is connected to AC power supply of
the building See (FIGURE 1.).
5.
The CM-1701monitor may be installed either under or on top of the table or workstation. There are two holes and
enclosed screws which can be used to attach the monitor to the workstation. Two sided pressure sensitive tape or
hook/loop Velcro may also be used.
OPERATION
Operator
When the path of the ground to the operator wearing the wrist strap is broken or the installed resistance of wrist strap
is higher or lower than the preset value (This mean the impedance of the user, wrist strap and ground is higher than
the preset value), the green LED of its testing side will change from the green LED to flashing red LED and buzzer
alarm.
