2 NORMAL MODE OPERATIONS
2.1 POWER-UP MESSAGES
“ POWER RESTORED ,” indicates the 1253 unit has correctly remembered all existing
menu settings, History File and Learnt Programs, after a mains supply interruption.
“
RESET
” indicates the 1253 has returned all menu settings to the default state, but left
the History File and Learnt Programs as they were.
This happens if the 1253 unit detects a fault in its database {existing menu settings).
This may occur (for example) if the unit has been without power for more than
1000hours, but not long enough to corrupt the history file and learnt programs 1 to 9.
1000hours is the time for which the internal battery is guaranteed to maintain the
memory.
“ INITIALISED ” indicates menu settings have been returned to the default state, and
the History File and battery maintained Learnt Programs (numbers 1 to 9) have been
erased. This occurs if the 1253 unit has been switched off much longer than 1000 hours.
Refer to Chapter 4, 1253 Menu Summary, for default values and parameter lists.
“ READY ” is displayed if the 1253 is no longer reset or initialised, but still has no
measurement readings to display.
2.2 DISPLAY
In normal mode the display shows measurements as selected by the relevant menus. A
measurement can be displayed, for instance, as:
1.106kHz +4.2172E+01 @ –3.65 deg
This is the default type of display, and shows a measurement frequency of 1.106kHz, a
gain of 42.172 and a phase shift of –3.65 degrees.
To vary the content and convention of the display use the DISPLAY menu.
