Installation
Otherwise the device may be damaged.
The two channels of the EL3692 are not electrically isolated. Measurements on live objects
should therefore be carried out in single-channel mode.
Attention
The following figure shows three potential applications; only the first two cases are possible. In the last case
either no measurement takes place since the terminal detects overvoltages at its inputs, or the measurement
is erroneous if the voltage at the DuT is still within the measurement limits of the terminal.
