9325-NU Quick Start Guide
Introduction/overview
The 9325-NU allows simple display of strain bridge-based measurements such as load cells and pressure gauges
with sensitivity up to +/-480 mV/V.
Up to six calibration ranges are available allowing for different loading modes (tension and compression) or
different sensors. Each calibration range will remember settings that contribute to the user experience such as
selected units and tare values.
TEDS devices using templates 33, 40 and 41 can be connected and will update the viewed calibration. The last
twenty TEDS devices connected will be remembered and recognized when connected again reverting to the last
user experience settings for that device. TEDS can be disabled, and the internal calibration ranges become
available again.

Select required input sensitivity (Note, this MUST be selected before the following
steps)
Return to previous menu
’UNITS’
Select required calibration units
Please note that this must be done in the correct order for the calibration to work
correctly. Changing the Sensitivity after inputting mV/V readings will cause the
calibration to be void. Always make sure you finish with Apply
