Connect only voltages that are within these limits.
DMM Isolation Voltages
Hazardous Voltage This icon denotes a warning advising you to take precautions to avoid electrical shock.
Channel-to-earth ground
Continuous...............................................................300 V, Measurement Category II
Withstand.................................................................3,000 V
Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level
electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.
Caution Do not connect the VirtualBench to signals or use for measurements within Measurement Categories III or IV.
DC Power Supply Isolation Voltages
+25 V and -25 V-to-earth ground continuous ........................60 VDC, Measurement Category I
Note Measurement Categories CAT I and CAT O (Other) are equivalent. The input circuits are not intended for direct connection to the MAINs
building installations of Categories CAT II, CAT III, or CAT IV.
