• Preforming measurement with a strain gauge requires a bridge box. Use a strain gauge and bridge box

both of which are commercially available.

• The bridge box may be susceptible to the effect of noise. For more information about how to ground the

bridge box, refer to its instruction manual or contact the manufacturer of the bridge box.

• Do not excessively bend the cable and the base between cable and connector, pull on them, nor twist

them. Doing so may cause the conversion cable to break.

Connection of Model L9769

• Pin F of the module end is connected with Pin A of the strain gauge transducer end.

• Pin G of the module end is connected with Pin C of the strain gauge transducer end.

When measuring current with a 9018-50 Clamp On Probe

You can use a voltage measurement unit such as the 8966 Analog Unit to make measurements. For more

information about how to configure the instrument for use in this type of application, see the example settings

in "7.4.1 Scaling Setting Examples" (p.150).

Applicable Modules

• Model 8971 Current Unit

Use to connect: Clamps

• Model 9272-10

Coneect Model 9318 Conversion Cable to

the module jack.

• 8971 Current Unit cannot be used with

MR8741.

• With MR8740, up to four 8971 Current

Units can be used.

Align the grooves of the unit sensor

connector and the conversion cable

plug. Insert the plug until it locks.

Align the grooves of the conversion

cable connector and the plug of the

clamp-on sensor to be used. Insert

the plug until it locks.

Connect the clamp sensor to the item

to be measured.

To disconnect the conversion cable:

Slide the plug to release the lock and

then unplug the cable.
