PROBLEM:
1. When sample is placed on pan, display
reading will not stabilize, i.e. jumps one
or more divisions.
2. Display will not change after sample is
placed on platform or always shows
overweight condition.
3. No readout appears in the display win-
dow.
THINGS TO CHECK:
A. Proper warm-up time is at least 30
minutes. It is recommended that the unit
be left on continuously.
B. Large machinery may cause vibration in
the work area. The scale should be
placed on a stable surface.
C. Excessive air movement can affect
stability. Scale should be located away
from air conditioners, fans, fume hoods,
etc. A breeze shield may be required.
D. Extreme changes in room temperature
can affect the internal calibration of the
unit.
E. The sub-platform is held in place by four
screws which may vibrate loose. Re-
move the platform to check.
IMPOR-
TANT: UNPLUG THE AC ADAPTER
FROM THE AC OUTLET PRIOR TO
REMOVING THE PLATFORM. Do not
over tighten screws.
F. Do not place the scale near magnetic
materials or instruments which incorpo-
rate magnets in their design.
G. Replace AC Adapter.
IMPORTANT:
Replace only with same voltage,
current, and polarity of originally
supplied adapter.
H. The line voltage to the scale should be
reasonably constant and free from fluc-
tuations. It is advisable not to share an
outlet with fluorescent lights or other
products which draw voltage in an in-
consistent manner.
I. Calibration memory has been lost. Re-
calibrate scale.
J. A/D converter is not stable or load cell
has failed. Return scale for repair.
