3.4 Mount the device
Prerequisites
Prepare the surface according to your mounting method. The mounting location is the
machine surface when using stud mount and the mounting pad when using epoxy mount.
The mounting location should be prepared according to best practices.
Procedure
1. To stud mount the device (recommended), prepare the machine surface using a
spot face tool. Then drill and tap a ¼ -28” hole 0.25” (6.35mm) deep. Alternately, a
mounting pad with ¼ -28” thread can be glued in place using epoxy.
2. With the cover still on the device, use your hand to loosely screw the device into the
threaded hole. Do not tighten.
3. Using your hand, loosely screw device into the mounting location.
4. Remove the cover and battery.
5. Set the device in the proper orientation. Insert a small screwdriver through the
guide hole in the base of the unit (shown below) and use this to hold the device in
the desired orientation.
Make sure that your planes are in the right direction. The Z plane should be vertical.
The orientation of the X and Y axis depends on how you configured your device.
To make sure that your X and Y axis stay where they are, use an allen wrench or a
small screwdriver while you torque down the device to make sure that everything
stays in the correct position. You can also hold the device while you torque it down.
6. While maintaining the device orientation, use a 3/16” ball driver to tighten the
captive screw in the center of the base (shown above) to 2-5 ft-lb.
The mounting screw must be tightened firmly but carefully to prevent stripping out
the mounting thread, typically 1/8 turn past finger tight for steel and slightly less for
aluminum or brass. For high-frequency applications above 7kHz and all PeakVue
