Portable Calibrating
Machine Guide
(PG-5401)
The Morehouse Portable Calibrating Machine (PCM) was designed and manufactured to address issues associ
-
ated with calibrating small force measurement instruments. The machine is highly versatile in accommodating
a large variety of configurations to which force measurement instruments are made at lower capacities (under
2,000 lbf).
Using proper adapters, several types of force instruments such as shear-web load cells, S-type load cells, beam
load cells, button load cells, ring force gauges, hand held force gauges, and small dynamometers can be cali

brated in a Portable Calibrating Machine. Features of the versatile calibration system are:
•
Capable of force calibration in both compression and tension
•
Portable design; machine weighs 32 lbs and is placed in a case with accessories
•
Calibrates force instruments up to 2,000 lbf
•
Exceptional force control capability to reach and maintain target test forces (e.g. 0.01 lbf using a 1,000 lbf
Morehouse Ultra-Precision Shear Web load cell)
•
Safe and confident calibration procedure for small instruments, which lowers risk of overloading the instru

ments
•
Built-in swiveling coupling nut to accommodate a variety of adapters and instruments
•
Compression bearing pad and ball seat adapter are included for calibrating compression-only instruments
When small force instruments are calibrated in large calibrating machines with high capacities, there is a high
risk of overloading the unit under test. The Portable Calibrating Machine lowers this risk by providing the user
high controllability over the applied force.
This guide describes different Portable Calibrating Machine models as well as the accessories and adapters
available for the machine to calibrate various types of instruments. For detailed information on the machine
operation and maintenance, refer to the Operation and Instruction Manual for the Portable Calibrating Ma
