Scaling Setting Examples
Using a Clamp-On Probe
To set automatically
To set manually (enter two-point numerical values)
The 9018-10 Clamp-On Probe provides 0.2 V output when measuring 10 A. So
Scaling should be set to display 10 A with 0.2 V input (and 0 A with 0 V input).
However, you may need to switch the vertical axis (voltage 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)
Example 1.
Measure with the 10A range of the Model 9018-10 Clamp-On Probe and
display the measured data in units of [A] (Amperes)
Select the clamp type to b
e
used.
1
Select the F1 [Clamp] button.
2
(When the range is displayed)
Select the same range as that s
et
with the clamp.
The Clamp Scaling dialog appears.
Select the [Exec] button.
Scaling is performed automatically to
suit the selected clamp.
