Operation
Preparation for Measurement
1. The 475044 or 474040 automatically determines TENSION or COMPRESSION
(Push or Pull) force during use. Compression displays as a negative value and
Tension displays as a positive value.
2. Select units of measure (grams/kilograms, ounces/pounds, or newtons) via the
units select button.
3. Attach the desired adapter (tension – hook; compression.- flat, cone or chisel head)
to the Universal Sensing Head.
4. Select FAST or SLOW response. The FAST setting permits the capture of fast
measurement changes and the SLOW setting provides an averaged reading
display.
5. Zero the display before each measurement via the Zero button.
Note: The sensing head with adapter must be in line with the object being measured.
Avoid rotating the sensing head. Refer to the figure below.
