To Select a Clamp Sensor
1. Move the cursor to
[Clamp]
, and select
[Select]
.
The cursor moves to

2. Select
[9000~]
.
The cursor moves to
[Clamp].
3. Select
[9018-50]
from the clamp list with
F
key, and select
[Confirm]
.
Units, scaling method, and ratio will be set automatically.
4. Select the same range of the clamp sensor when using the range selection type. Select
[10A]
here.
However, you may need to switch the vertical axis (voltage axis) range to suit actual input values.
For example, to display 0.2 V at full scale, set the vertical display to 20 mV per division (the
instrument's 20 mV/div range)

Before Scaling After Scaling
With scaling, signals from the sensor are acquired
as current rather than voltage.
AB cursors and gauges are displayed and printed
as current (Ampere) values.
Refer to “Gauge” (p. 116) or “Cursor AB Value”
(p. 109).
When using Model 8969 or U8969 Strain Unit
Example 2
To display data measured with the strain gauge transducer with a rated capacity
of 20 G and a rated output of 1000 µV/V in terms of gees (G).
For the rated capacity and rated output, consult the inspection record of the strain gauge
transducer to be used. Set the rated capacity and rated output so that the following expression
holds:
