In manual states, press it up jumper one step. If jumper from highest step to lowest step, only need pressed the key for 2 second, automatic switch into auto step. Hz/Duty and CAP because of the measure mode cannot switch into manual switch mode. Display hold˖HOLD HOLD Key is the PushType switcher, use for holding the display data. Relatively value display˖REL REL Key is the PushType switcher. Besides Hz/Duty, other measure ments have this function, it can automatic switch into auto switch mode. Auto poweroff When measure operating more than 15 minutes, and didn’ t switch the measure step (that is didn’ t press the push button), it will switch into standby mode automatically. If press the select key, auto power off invalidation. Back Light Control: When pressed the BLCTR or RANGE more than 2s, B1OUT will be set to “ 1” , and if press BLCTR again, it will be cleared. Beeper When selectǃRelǃHoldǃRangeǃHZ/DUTY and BLCTR keys pressed and function switched , the Beeper On about 0.5~1S. When ACV>750V, DCV>1000V, AC/DCµ A >4000µ A, AC/DC mA, AC/DC A>10A, the beeper will hold ON to indicator the warning of the out of range. At one minute before auto power off, beeper will beep five time s, and before shut down, beep one time.

All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken:
- Persons at a work bench should be earthed via a wrist strap.
- Equipment cases should be earthed.
- All tools used during assembly, including soldering tools and solder baths, must be earthed.
- MOS devices should be packed for dispatch in antistatic/conductive containers.
