16 User Manual - LCR Elite2 - ver 1.3
Protected by Aegis Technology
The Aegis Technology is our patent pending solution that automatically protect the meter from being damaged
by energized components.
The traditional LCR meters have a common vulnerability to high voltage and current from the component they
are measuring. In many cases, the component under testing can have stored energy, for example a charged
capacitor or a powered on board. The energy in the component is a common problem that causes damage to
LCR meters, thus requiring expensive and time-consuming repairs.
The Aegis Technology solves this problem. It provides over voltage protection up to +/-48Vdc (or +/-34Vac). In
normal operation, it is transparent and doesn't affect the measurement results thanks to the low parasitic
design. When an abnormal voltage is applied on the device's test tips, no matter positive or negative, the Aegis
Technology detects it right away and automatically disconnects it from the meter.
When the meter is in over voltage protection mode, the "OVER VOLT" message is displayed as Figure 3-7 shows.
To return to normal operation mode, please remove the meter from the component and press the navigation
button. No components are damaged and no fuse replacement is required.
