Measurement Module

H600 & SA2600 Service Manual
Each Li-Ion battery pack has an internal microprocessor that monitors its charge
level. To check the battery status, remove the battery from the analyzer. Then
press the PUSH button on the side of the battery and note the charge value on the
LED charge indicator.
Taskbar Power Status Icon. A battery icon appears in the taskbar when the
instrument operates from battery power. The icon displays the battery charge level
in 10% increments. If two batteries are installed, the icon displays the average
charge level of the two combined batteries. When the instrument operates from
AC power (from the Desktop Power Supply) a plug icon appears in the Taskbar
status area.
Battery System. The instrument uses up to two Inspired Energy type NI2020HD24
10.8 V, 7200 mAH, Li-ion batteries. You do not need special tools to replace the
batteries. (See page 4-24, Lithium-Ion Battery Maintenance.)
Battery operation characteristics include:
The battery power system operates the platform for approximately 9 hrs (12
watts load) from two Li-Ion batteries and approximately 4.5 hrs from a single
battery. Run time for the platform plus application varies depending on the
applications being run.
Only one of two batteries will be in use at any given time when two batteries
are installed.
If two batteries are installed, you can remove and replace either battery
without disrupting service.
If a second battery is installed, the platform automatically switches operation
to the second battery when the first battery reaches cut off capacity (5%
reserve) or is removed. The transition is transparent and does not interrupt
service.
Battery Power Management Utility. The Batteries tab in the Power Management
dialog box provides general information on battery status. This is the most accurate
information to determine battery charge status and probable manufacture dates.
(See page 4-26, H600 and SA2600 Instrument-Specific Battery Maintenance.)
The Measurement module contains no user-servicable parts. There are also no user
adjustments on the Measurement module. The entire instrument must be returned
for service. Service for the measurement module is not independently available.
