Portable Calibrating
Machine Guide
(PG-5401)
The Portable Calibrating Machine uses a high accura
-
cy load cell as the reference to measure the applied
force to the instrument under test. The reference
standard load cell is mounted to the top of the me
-
chanical jack through the standard mounting adapter.
The mounting adapter transfers force to the load cell
through the bottom shoulder of the load cell and
ensures that the standard load cell is loaded in the
same manner that it was calibrated.
Morehouse recommends that a Morehouse Ul
-
tra-Precision Shear Web load cell is used as the
reference standard in a Portable Calibrating Machine.
The standard mounting adapter is designed to mount
a Morehouse Shear Web load cell as the reference
standard into the Portable Calibrating Machine.
However, other types of cells can be installed in the
machine using a custom adapter.
To generate a quality calibration standard, the refer
-
ence standard load cell must be used in conjunction
with a high accuracy electronic indicator such as
Morehouse 4215 indicator or High Accuracy Digital
Indicator (HADI).
