the device passed the insulation tests; 5 sec at 2210 V RMS and impulse 4000 V. The
maximum operating input voltage is 1000 V DC. This device is to be used to measure
CAT II circuitry up to 600 V.
Measurement inputs of this instrument should not be used to measure high-energy signals
of measurement categories CAT II, CAT III or CAT IV (IEC 61010-2-030:2017) (e.g. mains
measurements) , unless speciîž’cally stated for the speciîž’c input.
2.4.2 Basic insulation versus reinforced
For reference, the basic insulation and supplementary insulation and the reinforced
insulation test values for CAT II can be found below.

Tab. 2.2 Test voltages for the testing electric strength of solid insulation in measuring
circuits in measurement category II (IEC 61010-2-030:2010)
Several means of protection can be used to protect a user from hazardous voltages.
As can be seen below, basic insulation and supplementary insulation is one mean of
protection, but reinforced insulation is also a means of protection.
The test voltages are different for each mean of protection, as can be found in the table
above.
