CALT 9 Progression
The CALT 9 supersedes the CALT 8B with the introduction of a bespoke internal computer. The
CALT 8B will continue to be supported for spares, maintenance, calibration, software and hardware
upgrades.
Hardware
The CALT 9 hardware includes all the features
of the CALT 8 with following new features:
•Interface autoswitch off
•Display sleep mode
•Li-ion battery pack
•External charger socket
•Comprehensive battery management
LEDs
•Audible alarm
•A single battery to power the interface
and printer and computer
•Low EM emissions and susceptibility
•Battery meter
Software
The software is based on the CALT 8B version
2.42 software which includes:
•Easy reboot
•Safe/protected calibration
•Multi-calibration (which allows a spare
transducer to be used)
•Combined measure volume and
leakage test if required
•Last test print out from main menu
•Automatic parameter testing
If you are a CALT 8 user you will be comfortable with the CALT 9, as the testing principles and the
test procedure remain unchanged.
The CALT 9 builds on the experience of both the CALT 8 and CALT 5, incorporating features to meet
users comments and generally to improve the instrument. Particularly noteworthy is the new Li-ion
battery pack. This is robust and will take a lot of abuse with respect to overcharging, over discharging
and being left completely discharged for months. The battery compartment is accessible by removing
front panel cover.
