3.10 About Setting Contents

Probe attenuation can be selected when measuring using a connection cable,

differential probe or attenuating probe. (Only for voltage measurement)

By matching the input channel probe setting to the attenuation ratio of a probe

connected to an analog input module, the voltage axis range is automatically

converted for direct reading of numerical values.

Each channel should be set to match the attenuation ratio of its input probe.

When using the Model 8940 F/V Unit with the 9322 Differential Probe:

When supplying power from the Model 9687 Probe Power Unit, either of the

above settings can be selected.

The factory default and system reset default setting is 1:1.

Set to suit the sensor to be used.

3.10.15 Probe Attenuation Selection

Setting Item: [Probe]

Selections Description

1:1

Select this setting when measuring with the Model 9197, 9198 or

9217 cable connected to the input module.

10:1

Select this setting when measuring with the Model 9665 10:1 Probe

connected to the input module.

100:1

Select this setting when measuring with the Model 9666 100:1

Probe connected to the input module.

1000:1

Select this setting when using the 9322 Differential Probe.

9322+9325

Select this setting when using the Model 9325 Power Cord to con-

nect the 9322 Differential Probe.

9322+9418

Select this setting when using the Model 9418-15 AC Adapter to

connect the 9322 Differential Probe.

Some probes cannot be used with certain input modules.

3.10.16 Bridge Voltage Setting

Setting Item: [Bridge]

Selections Description

2V Sets the bridge voltage to 2 V (Bridge resistance = 120 Ω to 1 kΩ)

5V Sets the bridge voltage to 5 V (Bridge resistance = 350 Ω to 1 kΩ)

10V Sets the bridge voltage to 10 V (Bridge resistance = 350 Ω to 1 kΩ)

This setting should not exceed the allowable applied voltage for the strain gauge

type converter to be used. Otherwise, converter specifications will not be satis-

fied, and correct measurements will not be possible.
