1.0 About your Tester
1.1 Description - What it can do
Your LARSON Hand Tester is a manually operated Force / Length Tester: it is designed to be portable and easy to use
for In-Process Control measurements right on the factory floor. The LARSON Hand Tester is light weight (about 22 lb)
and battery powered (optional on some models); hence, mobile for use wherever needed. The LARSON Hand Tester uses
LCD readouts for easy viewing of highly accurate length and force measurements. The length measurement units can be
selected to read in inches or millimeters while force measurement is selectable to read in pounds, kilograms, or Newtons.
The LARSON Hand Tester measures flexible items in either compression or tension. Although low in cost, the LARSON
Hand Tester features a high degree of built-in precision and accuracy to assure excellent repeatability and reproducibility.
All of the LARSON Hand Testers have DEFLECTION COMPENSATION for load cell and frame deflection. Because the
testers have compensation with Integrated force and length measurements, the length reads accurately at any force. This
eliminates the need to use look up tables to correct for the displayed length error. LARSON Hand Tester's length reading
is accurate as displayed.
The Testers are made with rugged cast aluminum and steel frames and instrumented with Larson's precision load cell for
force, glass scale for length and Larson's proprietary Precision Electronics for analysis and display of exact measurements.
RS 232 output (optional on some models) can be sent to computer, datalogger or printer for accurate transmission of data
for further analysis.
