Description
The switch output load current is 80 mA
or more.
During zero clear operation, pressure
greater than ±7% F.S. (±3.5% F.S.for
compound pressure) is present. Note
that the mode is returned to
measurement mode automatically 1
second later. The zero clear range
varies by ±1% F.S. due to variation
between individual products.
Pressure exceeding the upper limit of
the set pressure range is applied.
Pressure exceeding the lower limit of
the set pressure range is applied.
Displayed if an internal data error has
occurred.

Measures
Turn the power off and remove
the cause of the over current.
Then supply the power again.
Release the applied pressure to
atmospheric pressure, and retry
the zero clear operation.
Reset applied pressure to a level
within the set pressure range.
Turn the power off and on again.
If the failure cannot be solved,
contact SMC.
