Warranty and after-sales service
7.1 Warranty
The warranty lasts one year from the date of delivery. If
an equipment failure which is considered to be clearly at
the fault of
Watanabe
occurs during this period, we will
repair the equipment at no charge.
7.2 After-sales service
This product was manufactured, tested, and inspected according
to rigorous quality control procedures before it was shipped from
the factory. If an equipment failure should occur, please contact
your dealer or Watanabe(send the product to us). (Along with the
failed product, please include a description with as much
information as possible.)

Error in the internal memory of
the relay
Turn the power of the relay OFF and turn it ON
again. If the relay still does not recover, contact
our dealer or office.
Condition data error
Reset the condition data.
* Change at least one of the data in a parameter
and cycle through all of the other parameters.
Comparator data error
Reset the comparator data.
* Change at least one of the data in a parameter
and cycle through all of the other parameters.
Scaling data error
Reset the scaling data.
* Change at least one of the data in a parameter
and cycle through all of the other parameters.
Linearize data error
Reset the linearize data.
* Change at least one of the data in a parameter
and cycle through all of the other parameters.
Shift data error
Reset the shift data.
Digital zero value backup data
error
Perform a writing operation for the digital zero
value.
When an input or displayed
value is out of the measured
value range
Use the relay so that input and displayed values
are in the measured value range.
When the micro-computer is
waiting for data input
Make sure that the averaging frequency is not set
too high.
