7.4 Converting Input Values (Scaling Function)
148
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 flashing cursor to the [Clamp] item, and select [Select] .
The flashing cursor moves to the [Model] item.
2. Select [9000 ] .
The flashing cursor moves to the [Clamp] .
3. Select [9018-50] from the clamp list 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 flashing cursor to the [Setting] , and select [Reset] .
To copy the scaling setting to another channel
The Channel screen - [Scaling] sheet can be used to copy a setting.
See: "7.8 Copying settings to other channels (calculation No.) (Copy function)" (p.158)
Using the Scaling and Variable functions (p.153) in combination:
The full span of output from a sensor can be displayed. (p.155)
At factory shipping, automatic correction of the variable function (p.307) 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).
