16.2 Troubleshooting

When

Symptom

Possible Causes

Countermeasures

Before
measurement

Nothing appears
in the display.

The AC adapter is
not securely connected.
The power switchboard
of the room is turned off.
The power voltage
is incorrect.

Check power supply
and connect correctly.

Vibration or wind effects

Change the installation
site. Change the stability
and response settings
or change the stability
detection band.

Attempting to measure
volatile substances

Measure with a lid on it.

The weighed item is
electrically charged.

Measure in a metal
container. Measure with
a metal object larger
than the items.

The sample temperature
and the temperature
inside the weighing
chamber differ.

Measure at the same
temperature.
Leave the item in the
chamber before
measurement.
Change to high-stability
mode.

There are air currents
entering the weighing
chamber.

Leave the glass doors
of the weighing
chamber open 1 to 2
cm wide when not in
use.

Effects of electronic noise
or strong electromagnetic
waves

Move away from the
noise source.

The display fluctuates.

The stability mark does
not readily appear.

The measured results
have poor repeatability.

The display diverges
in the same direction.

“CAL d” appears
frequently.

Internal trouble with the
balance

Contact a service
representative.

During
measurement

“oL” or “-oL” is
displayed.

The load on the pan is
too large.
The pan is detached.

Use within the weighing
capacity. Place the pan
on correctly.
