installation. If a key has been locked, a long beep sounds when it is pressed. If
however, the key beeps normally, but does not appear to trigger the desired action,
it is waiting for the weight reading to settle before the action can proceed.
5.2.2. Editing Function
Available during digital setup and calibration. This function is displayed using the
editing annunciators above each key. Refer to Editing Annunciators page 17.
5.3. Stability Considerations
Once a <ZERO>, <TARE> or <PRINT> key is pressed the instrument waits for a
stable valid reading before performing the associated operation. If the weight
readings remain unstable or invalid due to some diagnostic error for longer than 10
seconds, the operation is cancelled and the STABLE ERROR message is
displayed.
To improve the stability of the weight reading, increase the filtering or relax the
motion detection criteria. Refer to FILTER (Reading Average) page 32 and
MOTION (Motion Detection)
page 32 for more information.
5.4. POWER Key
The <POWER> key is used to turn the instrument on and off. To initially turn
the instrument on, press and hold the <POWER> key. The display will show
the following:
•
Display segments will light and then clear.
•
Software Version (eg. V1.0).
•
Calibration Counter (eg. C.00010). Refer to Calibration Counter page 27 for
more information.
•
The current weight will then display.
To turn the instrument off, press and hold the <POWER> key for three seconds.
The instrument will display OFF followed by the three-second countdown.
When using batteries the backlight will automatically turn off to conserve power after
a short period of inactivity. A short press of the <POWER> key will turn the
backlight on again. Refer to B.LIGHT (Backlight Operation) page 36 for more
information.
Note: The <POWER> key can be locked to prevent the instrument being turned off
from the front keypad. Refer to KEY.LOC (Front Panel Key Locking) page 35 for
more information.
5.4.1. Automatic Operation
The <POWER> key on the instrument is unusual in that it has a memory function
associated with it. This means that the state of the power setting is remembered
even if external power is interrupted. It is therefore possible to turn the instrument
on in the safe knowledge that it will operate whenever external power is available
and will not need to be manually turned on again if the power is interrupted.
