Operation
Preparation for Measurement
1.
The 475055 automatically determines Tension or Compression (pull/push) force during use.
Compression displays as a negative value and Tension displays as a positive value.
2.
Select units of measure (kilograms, pounds, or Newtons) via the units select switch.
3.
Screw in the sensor hook and loop on the load sensor and then connect the sensor to the
meter via the input jack on top of the meter.
4.
Select FAST (0.2 seconds) or SLOW (0.6 seconds) update rate.
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 1.

Correct and Incorrect Angles of Measurement
Measurement Mode
1.
Slide the POWER switch to the ON (I)position. Reverse the LCD display if desired via the
Display Reverse key.
2.
Zero the meter before each measurement.
3.
Touch the adapter to the object being measured in a straight line. Refer to Fig.1.
4.
Begin measurement by applying force (Push or Pull). Read the LCD display.
5.
After completing the measurement, the display will indicate "0.00" if the position and angle of
the Force Gauge have not changed.
Note:
Be sure to press "ZERO" before taking a new measurement.
Overrange Indication
The Model 475055 uses a strain gauge sensor to measure force. Avoid subjecting the instrument to
forces outside the specified measurement range. The sensitive strain gauge can be damaged or
otherwise compromised by misuse. When an over-range condition is sensed by the meter the LCD
displays all dashes.
Note that the dashes are shown at the top of the LCD (
--------
) for tension measurements and at the
bottom of the display (
--------
) for compression measurements.
