3.3 Maximum Voltage Input
The R&S RT-ZHD high voltage differential probe is rated for CAT III environments with
following maximum working voltages between each input lead and earth ground.:
R&S RT-ZHD07:
300 V CAT III
600 V CAT II
600 V RMS / 4500 V
PK
R&S RT-ZHD15:
1000 V CAT III
1000 V RMS / 6800 V
PK
R&S RT-ZHD16:
1000 V CAT III
1000 V RMS / 6800 V
PK
R&S RT-ZHD60:
1000 V CAT III
1750 V RMS / 6800 V
PK
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 voltage against earth ground does not
exceed the maximum working voltage.
See also: Chapter 1, "Product Description", on page 5.
The rating ensures that the probe is protected against short transient overvoltages as
long as the maximum working voltage limit is observed.
Shock hazard caused by high transient overvoltages
Never use the R&S RT-ZHD probe for measurements in a higher category or at higher
effective working voltages than specified!
Do not use the probe to measure effective working voltages higher than the specified
voltage between each input lead and earth ground even if the effective differential volt-
age is lower than the specified voltage.
The maximum working voltage is derated for higher frequencies. Refer to the R&S RT-
ZHD data sheet for the specification of voltage derating over frequency.
