I'm using the Agilent E4980a LCR meter to measure the impedance of a system with the 4-terminal configuration. However, I need to introduce some changes in the system, so that it will be possible (not probable, but still possible) that, in case of an error, a 5 V DC voltage will be applied to the test terminals. Would that damage the LCR meter?

I searched in the manual and datasheet but couldn't find the answer. I only found the test signal voltage range (0 - 2 Vrms), but that's the normal measurement range. The question is: what is the maximum non-damaging test signal voltage?

Thanks in advance for your answers.
