Do not operate the instrument In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided particulates. In relative humidity conditions outside the instrument's specifications.
Clean the instrument only as instructed Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives, lubricants, solvents, acids/bases, or other such chemicals. Clean the instrument only with a clean dry lint-free cloth or as instructed in this manual. Not for critical applications This instrument is not authorized for use in contact with the human body or for use as a component in a life-support device or system.
Fuse replacement must be done by qualified service-trained maintenance personnel who are aware of the instrument's fuse requirements and safe replacement procedures. Disconnect the instrument from the power line before replacing fuses. Replace fuses only with new fuses of the fuse types, voltage ratings, and current ratings specified in this manual or on the back of the instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a fire.

Divide the voltage shown on the DMM by 3 (3Ω shunt) and use the number keys to enter the result. Press the ENTER key when complete. The instrument will show “OK” after Low Point(A). 6. Press Cal. softkey to start calibration 2, and the instrument will output the ML Point current.
YES, then press ENTER to confirm. 14.1.6 External Voltage Calibration Connect a DC power supply to pin 1 and pin 14 of Digital IO. The DC power must be able to supply 10V. CAUTION: The DC source for external voltage control and the DC source for external voltage calibration should be identical. And the external voltage calibration should be completed before using external voltage control function. Press System → Next → External Calibration softkeys in Setting and Measurement screen. 3.
then press the Next point softkey to calibrate the second point. 4. Supply 0V from the external DC power supply. The AD value should be 7900±300, then press the Next point softkey to calibrate the third point. 5. Input -9Vdc from the external DC power supply. The AD value should be 1000±300, then press the Next point softkey. 1.
