. BEFORE MEASURING
3.1 Cable Connections
3.1.1 Input Cable Connections
(1) Paste a strain gauge to the location where measurement is made.
(2) Connect the strain gauge to the bridge box.
(3) Connect the bridge box or a transducer to the input connector
１
on the rear panel. For
connection information, see Cautions before Measuring on page 4-1. Since Models
5683/5684 automatically adjusts the voltage drop generated between the bridge and the
amplifiers through the cable length compensation function, high-accuracy measurement is
possible. For more information on this adjustment function, see page 3-7.
(4) If you must measure large strains or wish to reduce the voltage going entering into the
transducer, you can change the bridge voltage to 0.5 V. Set the bridge voltage to 0.5 V using
bridge voltage selection switch 3 on the rear panel.

Bridge Box
When you yank this plug out of the
connector, you must hold this part
without rotating it.

Input Connector
Use a strain gauge with short wires between the
measuring point and the bridge box in order to
reduce noise as much as possible. Do not cut or
add wire as the strain
gauge performs gauge
factor calibration with the wires connected.
