Important Note:
When operating on batteries, the power saver function minimizes battery drain, although a very 
small amount of current is still required by the tester. Turn the power switch off to completely 
disconnect the batteries.
2.5 Wall Mounting
The supplied Wall-Mount Board allows the 3M
 
Shoes and Wrist Strap Tester 747 to be easily 
mounted on the wall while still being readily 
removable.
As shown in the figure below, the board is affixed 
to the wall with three screws (either M4 machine 
screws or 4.1 mm diameter wood screws). The 
Shoes and Wrist Strap Tester 747 is then attached 
to the board by align in the back-side mounting 
holes over the hooks on the board.
Important Note:
Screws are not included. Please use either M4 machine screws or wood screws with a nominal 
diameter of 4.1 mm for mounting. Either flat head or round head screws may be used.
3.0 Testing
When used as a stand-alone tester (that is, when not using the external output), 
the SIGNAL OUT test result output selector switch should be set to either 
WRIST or SHOES.
With the SIGNAL OUT switch set to either of these positions, both ESD shoes 
and wrist tests can be performed. 
To reduce the risks associated with electrostatic discharge (ESD), which, if not avoided, may result in 
property damage to electronic components or assemblies being handled.
•   Perform operational verification test to ensure proper operation of the 3M
 Shoes and Wrist Strap 
Tester 747 as required.
