CUSTOM Digital Multimeter CDM-7300

A multi-function type that can be used in a variety of situations. It has a bar graph display so you can check the changes in values  just like an analog meter.

• Voltage (DC, AC), current (DC, AC), resistance, frequency, capacitance, temperature, continuity check function, diode check function.
• The true RMS method allows the display of RMS values  for waveforms other than sine waves.
• Other features include duty check function, data hold function, relative comparison function, and MAX/MIN function.
• By using a conversion socket, K-type thermocouples with miniature connectors can be used, and the amplification factor (hFE) of transistors can also be measured.
• It has a backlight, making it easy to check the values  even when working in a dark place.
• It is equipped with an auto power off function to prevent battery drain.
• The 61-segment bar graph display allows you to see changes in values  just like an analog meter.
• The body is surrounded by rubber to absorb shock.

61-segment bar graph display

You can see the changes in the numbers just like an analog meter.

Alligator clip included

When attached to the tip of a test lead, the metal part of the clip is exposed.

The included conversion socket allows measurement of K thermocouples/transistor gain.

Connect to the input terminal on the main unit.
