Has a key been locked?
A single press of each key triggers the weighing operation printed on it. The instrument allows
individual keys to be disabled in the setup. All keys are enabled at the factory, but some keys
may have been intentionally disabled (locked) during 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.

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.
5.4.
Stability
– What is a “Stable Error”?
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
page 31 and
page 31 for more information.
5.5.
POWER Key
The
<POWER>
key is used to turn the instrument on and off. If the PWR.FN
feature is set to UNITS, then a short press of the <POWER> key will switch
units. 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
24 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 3s countdown.
Battery Operation:
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 33 for more information.
Unit Switching:
The <POWER> key will function as a unit switching button
with a short press by configuring PWR.FN to UNITS.
Locking:
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 33 for more information.
Automatic
Operation
The
<POWER>
key has a memory function associated with it. This means that
the state of the auto out 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.
