6. Insert the free end of the cable using

a small amount of tension into the
Wire Clamp Fixture and rotate the
handle clockwise until the cable is
clamped between the two metal
surfaces.

You are now ready to begin the
pull test.

7. Continue to rotate the lever

clockwise. The pull force on the

terminal connection will continue to
increase as the lever is rotated.

DO NOT EXCEED THE
MAXIMUM CAPACITY OF THIS
UNIT (110 lbs/50 Kg/500N) OR
DAMAGE COULD RESULT.

8. Eventually, the cable will pull out

from the terminal connection. The
test is now complete. If set for Peak
Capture Mode (refer to Overview of
Operating Modes, page 6), the peak
force value will be stored in the
display memory. If set for Average
Mode, the display would have been
updated throughout the test cycle.

9. To perform another test, repeat the steps detailed above. If operating in Peak

Capture Mode, be sure to press the ZERO key to delete the previously stored
peak value.

Model WTT-110RS testers can transfer measuring data by means of an RS-232C inter-
face. A 9-pin D-Sub connector is provided for this purpose, which can be found at the
left side of the instrument. A connector cable for the serial port is included. If a custom
serial cable must be used or if the user wishes to access the analog output, the pin
designations are as follows:

11.1 RS-232C Interface

The RS-232C interface can be used for the direct communication between an
appropriate serial I/O-card of a computer and the instrument. The minimum
requirement for the data transfer up to 19200 baud is the connection of the
RXD, TXD and GND communication terminal.
