Introduction

Thank you for selecting the Extech Digital Force Gauge. This professional meter, with proper care, will provide years of safe reliable service. This device measures Tension or Compression (Push or Pull) to 5kg (475040) or 20kg (475044). The reversible display indicates readings in grams, ounces, or Newtons. This meter offers Peak Hold and a Zero function. Please visit the Extech Instruments website (www.extech.com) to check for the latest version of this User Guide.

Operation

Preparation for Measurement

1. The 475044 or 474040 automatically determine 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.

Normal Measurement Mode

1. Slide the POWER switch to the ON position.
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.
6. If the position or angle of the Force Gauge changes during a measurement, the display may show one of the following:

a) The display over-ranges because the initial force of the transducer decreases due to a change in the position or angle of the Gauge after measurement.

b) The display indicates any value such as "12", "25", etc. This occurs because the initial force of the transducer increases due to a change in the position or angle of the Gauge after measurement.

Note: Be sure to press "ZERO" before taking any new measurements.

Mounting

For best results, mount the Digital Force Gauge to a test stand. Mounting holes are provided on the rear of the meter.

Battery Replacement

The low battery indication appears as a "LO" on the display when battery voltage is less than 6.8V. To replace the battery:

1. Remove the two screws from the battery compartment cover.
2. Lift off the battery cover.
3. Replace with 6 x 1.5V AA (UM-3) batteries. Observe polarity carefully.
4. Replace compartment cover and screws.

Battery Safety Reminders

• Please dispose of batteries responsibly; always observe local, state, and federal regulations with regard to battery disposal.
  • Never dispose of batteries in a fire. Batteries may explode or leak.
• Never mix battery types. Always install new batteries of the same type.
