WBK61 & WBK62

High-Voltage Adapters with Probes
Features• Provide up to 1000V (WBK61) or 100V(WBK62) inputs for the WaveBook andWBK10A• Ideal for 3-phase voltage ­measurements• Includes leads and probes• Accept differential inputs
The WBK61 and the WBK62 are singlechannel high-voltage adapters thatconnect to one of the WaveBook’s or
WBK10A’s BNC inputs. Each features
two safety-style banana-jack inputs for
signal “Lo” and signal “Hi” (rated at1000V, CAT II per IEC 1010-2-031).
Each adapter is resistively isolated fromground allowing safe connection of adevice under test. In the WBK61, both Lo
and Hi inputs are equipped with 10M Ohm
series resistors, which act as 200:1 attenuators and provide current limiting (100 µA,maximum current at 1000V). The WBK62
has a 1M Ohm series resister on both Lo
and Hi inputs, which acts as a 20:1 attenuator and provides current limiting (100 µA,­maximum current at 100V).

The WBK61 and the WBK62 high-voltage adapters connect to the WaveBook’s or WBK10A’s
BNC inputs
