Page 3: Introduction
Morehouse offers two sets of standard adapters that can be ordered to assist with calibration of a variety of force- measuring instruments: 1. -
Page 4: Construction
(PM-5401) Construction The Morehouse Portable Calibrating Machine is manufactured from high-quality material and to high-quality standards to provide users with a reliable and accurate force calibration system. The calibration force is generated using a mechanical screw jack which applies force in compression and tension modes. The jack is operated by turning the handwheel on the front side of the machine, and based on the direction of turning the handwheel, compression or tension calibration force is applied. -
Page 5: Dimensions And Weight
(PM-5401) Dimensions and Weight The Morehouse Portable Calibrating Machine weighs 40 lbs. The overall weight may vary depending on the load cell standard, accessories, and cases used with the machine. Morehouse supplies the standard Portable Calibrating Machine model in a protective case with wheels, which provides portability and contains the machine, load cell system component, and some adapters. -

To set up the Portable Calibration Machine for a compression-only calibration: 1. -
Page 8: Tension Setup
Before setting up a tension calibration, ensure you have the adapters needed to mount the unit under test and that they are rated for the forces that will be applied. Morehouse manufactures several adapter kits designed for tension calibration in Portable Calibrating Machines. To set up a tension calibration: 1. -
Page 9: Calibration
However, the user can continuously adjust the position of the mechanical jack to keep the force near the target force. Morehouse offers various types of load cell indicators that can be used to monitor the reference load cell output in ratiometric mV/V or direct force values in engineering units based on the user’s preferences. -
