4.1.5 PROBES AND RATIOS

4.1.5.1 CURRENT PROBES

The screen defines the current probes and ratios.
This menu enables you to define
■ Current probes (press A)
■ Current ratios (press V or U, depending on set-up)
Press A to define the current probes and ratios. This displays the current probe models detected by the instrument. If a
probe is detected but not managed, an error message is displayed.
For a 3-wire 3-phase set-up where only two of the three current sensors required are connected, if these two sensors are
of the same type and have the same ratio, the instrument simulates the third sensor by assuming the same characteristics
as for the two others. The third sensor will be shown in the list as either being simulated, or impossible to simulate.
The current probe choices that are available are:
If an MN193 clamp (5A range) or an adapter is used, the current ratio setting is proposed automatically. If an MN193
clamp (5A range), an Adapter, an AmpFlex
or sensitivity is proposed automatically.
Use the arrow buttons to define the ratios between the primary current (1A to 60,000A) and the secondary current (1A,
2A or 5A), then confirm the selections with the
current.
