Precautions • 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.
• When executing shunt calibration, be sure to calculate the shunt resistance in advance, and
execute it in a range so that the measured values do not exceed the range even when the
shunt resistance is ON.
• 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. Perform sensing as close to the bridge
head as possible. (There is no conversion cable for sensing on D-Sub connector types.)
• The connector shell is connected to the case potential.
• When a bridge head (701957 or 701958) is used, the connector shell, cable shield, and the
bridge head case are all connected to the case potential of the DL350.
• When a bridge head (701957 or 701958) is used, the connector shell, cable shield, and the
bridge head case are all connected to the case potential of the instrument.
• Be sure to execute balancing again when you change the range or the bridge voltage.
