Maximum Voltage Input
The R&S
RT-ZD01 high voltage differential probe is rated for CAT III environ-
ments with a maximum working voltage of 1000
V
(RMS) between each input
lead and earth ground. Thus, it can be used to measure electrical devices or
installations of categories 0 (I), II, or III if the effective value of the measured volt-
age against earth ground does not exceed 1000
V
(RMS).

chapter 1.2, "Measurement Categories"
The rating ensures that the probe is protected against short transient overvol-
tages as long as the maximum working voltage limit is observed.
Shock hazard caused by high transient overvoltages
Never use the R&S
RT-ZD01 probe for measurements in a higher category
or at higher effective working voltages!
Do not use the probe to measure effective working voltages higher than
1000
V
(RMS) between each input lead and earth ground even if the effec-
tive differential voltage is lower than 1000
V
(RMS).
The maximum working voltage is derated for higher frequencies. Refer to
the R&S RT-Zxx data sheet for the specification of voltage derating over
frequency.
