The disturbance test of all the models meet the limit values of A in the standard of EN 61326: 1997+A1+A2+A3, but can’t meet the limit values of B.
WARNING
IEC Measurement Category II. The HI and LO input terminals may be connected to mains in IEC Category II installations for line voltages up to 300 VAC. To avoid the danger of electric shock, do not connect the inputs to mains for line voltages above 300 VAC.
Protection Limits: To avoid instrument damage and the risk of electric shock, do not exceed any of the Protection Limits defined in the following section.
IEC Measurement Category II Overvoltage Protection
To protect against the danger of electric shock, the RIGOL DM3000 series Digital Multimeter provides overvoltage protection for line-voltage mains connections meeting both of the following conditions: The HI and LO input terminals are connected to the mains under Measurement Category II conditions, defined below, and The mains are limited to a maximum line voltage of 300 VAC. IEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit.
Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The DM3000 series Digital Multimeter may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the DM3000 series Digital Multimeter may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltage that may exceed the protection limits of the DM3000 series Digital Multimeter.
Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltage are also present on circuits that are isolated from mains. The DM3000 series Digital Multimeter is designed to safely withstand occasional transient overvoltage up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltage could exceed this level.
