Application examples
Figure 4.1: Observing in circuit
Note:
Pay attention that the observed circuit is completely floating in other
case the short circuit will arise through oscilloscope grounding.
Figure 4.2: Testing to supply voltage variations or supplying the equipment with other rated
AC power supply voltage
Notes:
PE shall be connected as shown if observed equipment requires TN/TT
supply voltage condition.
The PE of observed equipment might be connected to the PE of supply
system for special purpose only, e.g. as functional earth or additional
guarding to minimize EMI problems.
To prevent unintentional working conditions or even damage of the
observed equipment, set the output voltage into rated supply voltage
range of observed equipment and then connect the equipment to MA
4804 output.
