SECTION 1 – INTRODUCTION & INSTALLATION
INTRODUCTION
The Measurement Systems International MSI-9300 Series Porta-Weigh Plus Crane Scales are designed to
provide a rugged weight indicator and data system for any type and size of crane used in industry. Two basic
styles are available: MSI-9300 and MSI-9300HT. This guide is used for both versions as they have identical
electronics.
The standard MSI-9300 is supplied with rotating hooks or shackle interfaces. The MSI-9300HT Hi-Torque
version features a fixed load train that does not rotate and a new load cell design that withstands the induced
torque associated with power assisted rotating loads. With options available for both top and bottom inter-
faces, the MSI-9300HT easily integrates with existing powered rotators to provide safe material handling and
increased operational efficiency. The MSI-9300 Series combines CellScale technology with MSI’s advanced
Crane Scale architecture providing both a local and remote display capability. Combined with CellScale acces-
sory components, they become advanced data gathering networks suitable for process control, safety monitor-
ing, and weight related data collection.

The circuitry is fully shock-mounted and water proof making a robust
overhead weighing system for use indoors and out. The large 1.2” (30mm)

ness can be set to automatically adjust to ambient lighting conditions for
optimum viewing and battery conservation.
The MSI-9300 Series crane scales can communicate with CellScale family
indicators and modems at distances up to 1000’ (300m) outdoors (even
further with gain antennas). Both fixed and handheld indicators are avail-
able, as well as Modems for direct connection to computers. A remote
4-20mA interface is available for direct connection to PLCs and other
process control equipment. CellScale Virtual Monitor (CVM) software is
available to enable your PC to act as a full-featured digital scale indicator
with data logging capabilities.
INSTALLATION
The MSI-9300 installs easily by hanging it on the crane, using properly
sized shackles. Follow proper loading procedures to ensure that side load-
ing is eliminated. Please refer to MSI’s brochure, “Crane Safety” when
installing model MSI-9300.
