Current Range - East Tester ET5406A+ User Manual

ET5406A+/ET5407A+ Programmable DC Electronic Load - User Manual
Within the non--system parameter setting interface, i.e., during operation mode, users can
also swiftly switch between the high and low voltage ranges using the [V_R] button when the
channel is inactive.

2.5.4. Current Range

I rAn, there are two current ranges available. The high range, denoted as HIGH, displays
current values with two decimal places; the low range, denoted as LoW, displays current values
with three decimal places.
Within the non--system parameter setting interface, i.e., during operation mode, users can
also swiftly switch between the high and low current ranges using the [I_R] button when the
channel is inactive.
2.5.5. Voltage/Current/Power Limits
If the measured transient voltage exceeds the voltage limit for 20ms, over voltage protection
will be triggered, and the "OV" and "LOCK" icons will be displayed on the interface, indicating
an Over Voltage condition, button lockout, and forcible channel deactivation.
If the measured transient current exceeds the current limit for 20ms, over current protection
will be triggered, and the "OC" and "LOCK" icons will be displayed on the interface, indicating an
Over Current condition, button lockout, and forcible channel deactivation. Users can press the
[ENT] button to release the abnormal state.
If the measured transient power exceeds the power limit for 20ms, over power protection will
be triggered, and the "OP" and "LOCK" icons will be displayed on the interface, indicating an
Over Power condition, button lockout, and forcible channel deactivation. Users can press the
[ENT] button to release the abnormal state.
The voltage, current and power limits can be defined in the system settings, as shown in Fig.
2-5-5-1 below.
