83 series digital multimeter is a convenient operation. readings accurate. functional. Compact. portability. running on battery power, handheld portable large screen liquid crystal display digital multimeter, for engineering design. laboratory. trial production. workshops. field operations and industrial maintenance applications.
The multimeter has the following main features:

CMOS integrated circuits. principle of dual-slope integration a/d conversion, auto zeroing, automatic polarity selection, overrange indicator.

Lines through a short beeping sound when the test Dyke shows

     EXCEL's new DT830 digital multimeter, the appearance of new, more in line with international safety standards. Increases the hold function, automatic shutdown function, buzzing noise, and configure the test probes conforming to international standards.

This meter has the following characteristics:
• CMOS integrated circuits, principle of dual-slope integration a/d conversion, auto zeroing, automatic polarity selection, overrange indicator.
• LCD screen with high contrast large-screen 70x40 mm, up to 25 mm. Based on location, the display screen can be about 70 ° angle of vision in order to obtain the best result.
• Automatic power off function, about 25 minutes after the power will automatically cut off the power supply in case the instrument after use on forgot to turn off the power supply. Repeat power switch operation, you can continue to boot.
  ¡Ø new optimal design of highly reliableprocess/function rotary switches the structure. Based on 32-bit and more effectively to avoid misuse. Pay attention to maintenance

The digital multimeter is a precision electronic instrument, do not arbitrarily changed the internal circuit to avoid damage.
1, do not get higher than the voltage more than 1000V DC or 750V AC valid values.
2, not mistaken circuit outside the range so as not to damage.
3, the instrument do not use when the back cover is not good.
4, replace batteries and fuse shall be appropriated to and after power is turned off. Rotate the rear cover screws, gently lift the rear door and look both forward and back cover so that hooks on the rear cover from the instrument surface shell that is remove the back cover. According to the back cover notes specifications, replace the battery and the fuse.
