4.6.4. Standby Battery Voltage
Standby battery voltage parameter is intended for checking the built-in battery. The
standby lithium battery has a rated value of 3 V. If the measured battery voltage is greater
than 2.5 V, then
norm status is indicated. If the voltage is less than 2.5 V, then low status
is indicated. The battery function is a power supply to the system clock, memory (for
saving the current Analyzer settings), and NVRAM of the Data Logger for the case when
the main batteries are not available. If
low status is indicated, the IT-088 should be sent to
repair service to have its battery replaced.
4.6.5. Program Memory Check
This program checks the program memory of IT-088. If the test does not detect any
error, the norm status is displayed. If an error has been detected, an error status is
displayed, in this case the software must be reinstalled, as described in section 4.10.
4.6.6. Base Unit Check
This program checks the condition of the Base Unit components. If the test does not
detect any error, the norm status is displayed. If an error has been detected, an error
status is displayed, in this case the Analyzer should be sent to repair service to have the
defects corrected.
4.6.7. Removable Module Check
This program checks the condition of the Removable Module components. If the test
does not detect any error, the norm status is displayed. If an error has been detected, an
error status is displayed, in this case the Analyzer should be sent to repair service to have
the defects corrected.
4.6.8. Data Logger NVRAM Check
This program checks the condition of the Data Logger nonvolatile memory, NVRAM. If
the test does not detect any error, the norm status is displayed. If an error has been
detected, an error status is displayed, in this case correct this error by means of the
memory manager test, as described in 4.5 section. If a memory error occurred the
program may “freeze” or reboot during the testing process. In this case it is necessary to
erase the memory completely. If an error cannot be eliminated, the Analyzer should be
sent to repair service to have the defects corrected.
4.7. User Interface Setting
4.7.1. General Information
The operating parameters setting program is intended for modifying the general
parameters of the Analyzer operation. The icon in the main menu corresponds to the
this program. See figure 4.34:
