Energy Saving Mode
The ESIB offers an energy saving mode for the screen display. The screen goes blank if no entries have
been made from the front panel (key, softkey or hotkey and rollkey) for a selectable period of time.
To switch on the energy saving mode:
1. Call the SYSTEM DISPLAY - CONFIG DISPLAY submenu to configure the screen display:
½ Press the DISPLAY key
½ Press the CONFIG DISPLAY softkey
2. Activate the save mode
½ Press the SCR. SAVER ON softkey.
The softkey is highlighted, indicating that the energy saving mode is on. At the
same time the data entry for the shutdown time opens.
3. Enter the shutdown time
½ Press the SCR. SAVER TIME softkey.
½ Enter the shutdown time in minutes and confirm the entry using the ENTER key.
The screen will go blank when the shut down time elapsed.
Battery Backed-up Memory
The ESIB has a battery-powered read/write memory (CMOS-RAM) for backing up instrument settings
on power-off. After each power-on, the ESIB is reloaded with the operational parameters which were
active just prior to the last power-off (STANDBY or AC power OFF) or were set with AUTO RECALL
(see Chapter 4 "Saving and Recalling Data Sets").
A lithium battery powers the CMOS-RAM. When the battery goes flat (after approx. 5 years), any data
stored in the CMOS-RAM will be lost. If this happens, the factory setup is loaded on power up. As the
ESIB has to be opened to replace the battery, please contact the representative of our company
responsible for you for changing batteries.
Function Test
On power up, the ESIB displays the following message on the screen:

Booting
A self-test of the digital hardware is then performed. If the self-test finds no faults, Windows NT is
booted up and the instrument starts measuring.
Any errors which occur in self-test are transferred as ASCII text to the printer interface (LPT). Therefore,
an error diagnosis can be carried out, even for serious failures.
A check of the data contents of the instrument is performed in system error correction (CAL, CAL
TOTAL key) The individual results of the correction (PASSED / FAILED) can be displayed in the
calibration menu.
With the aid of the built-in self-test functions (INFO key, SELFTEST soft key), the functional integrity of
the instrument can be verified and/or defective modules can be localized.
