Specifications
• Highly sensitive measurements are made in the µV level in strain measurements.
Therefore, take measures against noise at the strain sensor perimeter, bridge head, and
cable wiring.
• Depending on the noise environment, an error may result in the balance. Check the
influence before making measurements.
• The bridge head specified by YOKOGAWA has high noise resistance.
• Some of the strain gauge sensors and bridge heads made by other manufacturers
do not have sensing wires connected. (No such problems with bridge heads made by
YOKOGAWA.) If such products are used, an error may result in the bridge voltage leading
to measurement errors, because sensing does not work effectively. If possible, it is
desirable that sensing be done very close to the bridge. However, if this is not possible, use
the NDIS conversion cable (DV450-001) that is sold separately by YOKOGAWA.

• The connector shell is connected to the case potential.
• When a bridge head (701955 or 701956) is used, the connector shell, cable shield, and the
bridge head case are all connected to the case potential of the DL850E/DL850EV.
• When a bridge head (701955 or 701956) is used, the floating GND is connected to the
bridge head case inside the bridge head.
• Be sure to execute balancing again when you change the range or the bridge voltage.
