This is a HTC Instrument DM-81 Digital Multimeter Capacitance Diode Transistor and Live Tester. This brand new and Latest Digital Multimeter Small Yellow Color LCD AC DC Measuring Voltage Current is a Small Multimeter for your day to day needs. If you have basic knowledge about Multimeters you can try this small Multimeter for basic continuity checks, Voltage Measurements and many more. A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common than analogueue ones, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly-varying. When testing the magnifying ratio of the transistor, turn the switch to the hFE position and connect the transistor to the eight-hole jack available in blue colour. For the Square wave output, the frequency is 50Hz, the voltage is approximately 3Vp-p. The output jack is “VΩmA” and “COM”.
