CHAPTER 1
Introduction
The SURETEST is a laboratory grade instrument that provides
TORQUE measurements. Although designed as an independent digital
indicator, it can also be used in an integrated environment as the
principal component of a Torque Calibration System. The SURETEST
features versatile data acquisition capabilities including measurement
storage, retrieval, statistical analysis and automatic downloading to an
external printer/computer. A remote computer COM port is available for
PC interfacing.
Used with precision torque transducers, the SURETEST provides high
speed monitoring of static or dynamic torque inputs. Torque transducers,
purchased separately, are available in ranges from 15-200 in- oz, to 200-
2000 ft-lb, and provide system readings with an accuracy of ± 0.25% of
indicated value, or better. A special memory chip is built into each
torque transducer that identifies its range and maintains its calibration
between any other SURETEST with an accuracy of ± 0.5%. The
SURETEST and its transducers may be calibrated by using accessory
precision bars and certified weights.
All readout of torque in ft-lb, in-lb, in-oz, Nm, dNm, cNm, mkg as well
as calibration, statistical analysis and set-up functions are reported on a
versatile 1.5” x 5.5” graphic dot matrix Liquid Crystal Display (LCD).
Set-up and calibration programming is entered using easy-to-use front
panel membrane keys. The number of keys is kept to a minimum. In
addition, concise menus and graphic symbols are used to guide the user
through all set-ups and operations. HIGH and LOW torque limits are
adjustable to give an audible alert. The user selects TRACK mode to
display torque values as they are applied, PEAK HOLD or POWER
TOOL modes to display the highest torque value applied, or FIRST
PEAK mode which captures the torque output at the “click” of a set-able
wrench or driver. CLEAR, STORE and SEND functions can be set up
for automatic or manual operation.
The SURETEST stores and recalls up to 3000 torque readings and does
statistical analysis on them for downloading to printer or computer. The
statistical report (print out) includes a simple histogram for process
monitoring. True RS-232 serial printer and separate RS-232 computer
COM ports are at the back of the unit.
