Do not insert anything into the holes of the fan to avoid damaging the instrument. Use Proper Fuse. Please use the specified fuses. Avoid Circuit or Wire Exposure. Do not touch exposed junctions and components when the unit is powered. DM3068 Performance Verification Guide... - Page 5 RIGOL Do Not Operate With Suspected Failures. If you suspect damage occurs to the instrument, have it inspected by RIGOL authorized personnel before further operations. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.
- Page 6 4) The current input into the 10A terminal cannot exceed 13.5A; otherwise, the internal fuse of the multimeter will be burned out. The current input into the LO Sense/200mA terminal cannot exceed 650mA; otherwise, the current input fuse on the rear panel may be burned out. DM3068 Performance Verification Guide...
- Page 7 DM3068 may be used to make measurements with the HI and LO inputs connected to mains in such devices (up to 300VAC), or to the branch socket. However, the HI and LO inputs of DM3068 cannot be connected to mains of permanently installed electrical devices such as a main circuit-breaker panel, sub-panel disconnected box or wired motors.

Page 18: Test Conditions
Ground the shield of the twisted pair and the shield of the coaxial cable. Unless otherwise noted, ground the LO terminal of the calibrator. As DM3068 is a high-precision measuring instrument, special attention should be paid to the additional error caused by the calibration source and calibration operations. In ideal situation, the accuracy of the verification test and calibration standard source must be at least four times higher than that of the test instrument. -
