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.

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.

Remove the sensor hook/loop from the "S" load cell for a PUSH or compression measurement.

Over Range 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.

Peak Load Measurement

1. Slide the POWER switch to the PEAK position.
2. Touch the adapter to the object being measured in a straight line, refer to Fig. 1.
3. Zero the meter before each measurement.
4. Begin measurement by applying force (pull or push). The LCD will display the peak value, which is the highest reading encountered.
5. After completing the measurement, the display will hold the peak reading until a higher reading is reached or the switch is moved out of the peak hold position.

Note: Be sure to press "ZERO" before taking a new measurement.

Remove the sensor hook/loop from the "S" load cell for a PUSH or compression measurement.

Fast/Slow selection

Press the FAST/SLOW key to select the desired display update rate. The "FAST" icon will appear in the display when FAST is selected.

Display Backlight

Pressing the backlight button momentarily will turn on the backlight. After approximately 15 seconds, it will automatically shut off.
