Do not exceed the maximum permitted input values. Do not touch any circuits or
parts of circuits if there could be voltages higher than 50 V ACrms or 75 V DC present
within them. Danger to life!
Before measuring, check the connected measuring accessories for damage such as,
for example, cuts, cracks or squeezing. Never use defective measuring equipment!
