Maintenance

The fastest charging method is to charge the internal batteries with the Plus Flow
Analyzer Test System turned off. With new batteries and the instrument turned off, the
charging time to go from empty to a full charge is approximately 4 hours. When connected to AC
power, the Plus Flow Analyzer will charge the internal batteries during operation;
however, the time to full charge will be extended. The batteries cannot be charged externally from
the Certifier Flow Analyzer.
The Interface Module can be powered by internal Lithium-Ion battery or an AC power adapter can be
used. If the AC adapter is delivering power to the Certifier Interface Module and the battery is installed,
a lightning bolt symbol will be displayed in the battery icon to indicate active battery charging.

The Certifier Plus Flow Analyzer comes with the battery pre-installed into the 4089 Interface Module.
The battery will function for four or more years with normal operation of the Certifier Plus test system.
To remove or install a battery, a Philips-head screwdriver is required.
To remove a battery from the Certifier Plus Flow Analyzer:
• Turn the Certifier Interface Module off and disconnect any cables
• Remove the protective cover (if attached)
• Remove the cover on the back side of the Certifier case by unscrewing the 3 screws
• Disconnect the battery pack by unplugging the pigtail connector from the Certifier Flow Analyzer
