When in Setup the editing annunciators are shown to identify the function of the front
panel keys (i.e. GRP, ITM, SEL, EDT and OK). For more information refer to Editing
Annunciators page 18.
5.2. 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.
5.3. Editing Function
Available during digital setup and calibration. This function is displayed using the editing
annunciators above each key. Refer to Editing Annunciators page 18.
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 FILTER (Reading Average) page 34 and MOTION (Motion
Detection)  page 34 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 (e.g. V4.0).
• Calibration Counter (e.g. C.00010). Refer to Calibration Counter page 25 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 37
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 36 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.
