Site Preparation
Select a suitable location for the spark tester:
The DC-B Spark Tester is designed for use in a fixed location, permanently
connected to its power source. The unit may be mounted on a table or on a
Clinton floor stand and should be placed at wire line height and within easy reach
of the operator. For detailed dimensions of the spark tester, please see the
specification sheet.
The spark tester should be adjusted so that the product runs centered in the
electrode in both the vertical and horizontal axes and parallel to the mounting
plate. Vertical and horizontal dimensions for wire centers for standard electrodes
can be found on drawings supplied with this manual. For non-standard
electrodes, or for copies of the required drawings, contact the Engineering
Department of The Clinton Instrument Company.
When the spark tester is to be placed on a primary or jacketing (sheathing)
extrusion line, it is desirable to locate the equipment as close to the extruder
cross-head as practical, this generally means locating it just after the water
cooling trough. In this case it is important to wipe the water off of the product
thoroughly before it enters the spark tester electrode containment. Failure to
adequately dry the surface of the wire or cable can cause false-counting, and can
cause premature failure of the equipment.
To mount the unit on a horizontal surface:
With a screwdriver, remove the (4) plastic feet from the tapped inserts in the
bottom of the spark tester chassis. Insert (4) M-6 screws through the mounting
surface into the (4) tapped inserts. Be sure the screws do not extend into the
chassis more than 1/2 inch (12mm).
To install the unit on a Clinton floor stand:
Assemble the floor stand as shown in the drawings at the back of this manual.
Secure the tripod base of the floor stand to the shop floor using 1/2” (12mm)
bolts and washers. Remove the (4) plastic feet from the tapped inserts on the
bottom of the spark tester chassis, as shown above. Mount the spark tester to
the stand by feeding (4) M-6 screws supplied with the floor stand through the
bottom of the floor stand plate and into the (4) tapped inserts in the bottom of
the spark tester.
