4.3.5 Sensors and Ratios
A first screen
displays the current sensor models detected by the device. It can also be used to
define the transformation ratio (sensitivity) of certain current sensors (SL261 clamp).
The probe choices are:
MN93 clamp: 200A
MN193 clamp: 100A or 5A
SR clamp: 1000A
AmpFlex
MiniFlex
MR clamp: 1000A
SL261 clamp: 100A (sensitivity 10mV/A)
SL261 clamp: 10A (sensitivity 100mV/A)
Three phase adapter: 5A
If an MN193 clamp, 5A range, or an Adapter is used, the current ratio setting is
proposed automatically. The configuration is done as follows:
•
To configure the primary circuit current (1A to 60,000A) / secondary circuit
current (1A, 2A, or 5A) transformation ratio, press
use ◄ or ►.
•
To select the values, use ▲ or ▼. Proceed in the same way for the primary and
secondary circuit currents.
•
