high accuracy, high speed meter. Allows multiple calibrated
ranges. Optionally, the DSM-Plus can have two channels
to read force and strain. This is a simple, low cost
way to obtain the data for stress-strain plots.
The DSM-Plus is ideal for customers who own several
extensometers. The automatic recognition feature allows
each extensometer to be calibrated individually on
one meter. When the extensometer is plugged in, the
meter automatically recognizes it. When power is turned
on the calibration data for this extensometer is recalled
from memory. It is also possible to calibrate the
same extensometer in multiple ranges. For example,
it is frequently convenient to calibrate an extensometer
to a range of 10% of the full scale travel to allow
greater sensitivity for tests at small strains.
The dual channel version is very useful for tests
which require two strain readings, such as measurement
of Poisson's ratio or r-value tests on sheet metal
samples. It also is a low cost solution to upgrading
older test systems. One channel is used for strain
and the other for the force reading from a load cell.
The RS232 digital output or the analog outputs make
computerized data acquisition simple.
