FUNCTION DESCRIPTION
Auto/manual switch RANGE
RANGE is the Push-Type switcher, and set in auto switch at power-on. If pressed RANGE key, it switch into
manual step. 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 Push-Type switcher, use for holding the display data.
Relatively value display REL
REL Key is the Push-Type switcher. Besides Hz/Duty, other measurements have this function, it can automatic
switch into auto switch mode.
Auto power-off
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 select
Rel Hold
Range HZ/DUTY and BLCTR keys pressed and function switched , the Beeper
On about 0.5~1S. When ACV>750V, DCV>1000V, AC/DCµA >4000µA, 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 times, and before shut down, beep one time.

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. 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.
