8.5 Converting Input Values (Scaling Function)
130
The 9018-50 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).
Selecting a Clamp Type ___________________________________________
1. Move the cursor to the [Clamp] item, and select [Select].
The cursor moves to the [Model] item.
2. Select [9000 ].
The cursor moves to the [Clamp].
3. Select [9018-50] from the clamp list with F key, and select [Confirm].
Units, scaling method, and ratio are set automatically.
4. Select the same range of the clamp when using the range selection type.
Select [10A] here.
To reset Scaling settings:
Move the cursor to the [Method], and select [Reset].
To copy the scaling setting to another channel
The Channel screen - [Scaling] sheet can be used to copy a setting.
See: "8.9 Copying settings to other channels (calculation No.) (Copy function)" (
p.139)
Using the Scaling and Variable functions ( p.134) in combination:
The full span of output from a sensor can be displayed. ( p.136)
At factory shipping, automatic correction of the variable function ( p.257) is set
to [On].
At this time, the Variable setting is altered so that it is linked to (dependent upon)
the vertical axis (voltage axis) range and scaling settings. If you want the Vari-
able function setting to take priority, use either of the following procedures:
• Set Scaling first, and then set the Variable function
• Set a Variable value before Scaling, and then set Scaling.
When automatic correction of the Variable function (Variable Auto Adjustment) is
disabled (Off), the Scaling and Variable settings are unlinked (independent of
one another).
