Humboldt HM-1327 Humboldt Marshall/TSR Loader - Manual (Page 9)

If you are using third-party cables for load cells/transducers connections,
make sure they are wired to be compatible with the HM-1327. Consult
Figure #1 for a compatible reference wiring diagram. Plugs to connect
third-party instrumentation to the Humboldt HM-1327 are available, order
part HM-000474.
Mounting Load Cells and Transducers
If you purchased your HM-1327 with instrumentation, one of the load cell/
transducer setups should already be mounted. If you are using the machine
for multiple tests or want to use instrumentation not included, including
third-party instrumentation, the following photos can be used as a guide for
load cells/transducers setup.
