How to Measure Temperature Temperature Measurement: Connect the k-type thermoelectric couple to V mA Jack and COM jacks.How to use Multimeter to check voltage, Ohms, battery, continuity etc is more or less the same.
The only difference is that a digital Multimeter has a digital display of all the readings. An analog Multimeter has a needle-type pointer that moves to a reading while testing any device or electronic component. Most Multimeters, often spelt as Multi Meter, will have following: Function and Range Switch: This switch is used to select the function and desired range as well as to turn the instrument. In order to extend the life of the battery of the Multimeter, this switch must be kept in the OFF position when the instrument is not in use. Common Jack: Plug in connector for black (negative) test lead or probe. V mA Jack: Plug in connector for red (positive) test lead or probe for all voltage, resistance and current (except 10A) measurements. A Jack: Plug in connector for red (positive) test lead or probe for 10A measurement. Packing List or Items that come with a New Multimeter: Multimeter. Set or red and black test leads or probes. Battery. Thermoelectric couple. If the voltage to be measured is not known then set the Switch to the highest range and reduce it until satisfactory reading is obtained. Turn ON Power of the device, instrument or component being measured. Voltage will appear on the Digital Display of a Digital Multimeter along with voltage polarity. Connect Test Leads to device, electronic component or circuit being measured. Voltage value will appear on the Digital or Analog Display the Multimeter. How to Measure DC (Alternating Current) Current Using a Multimeter DC Current Measurement: Connect the red probe to V mA Jack and the black probe to COM jack. To measure DC current between 200mA and 10A, connect the Red probe to 10A jack with fully depressed. Use An Analog Multimeter Series With TheOpen the circuit to be measured and connect probes in series with the load in which current is to be measured. If the resistor to be measured is connected to a circuit then TURN OFF POWER and discharge all capacitors before measurement. Connect Red Test Leads to Anode of the Diode and Black Test Lead to Cathode. The forward voltage drop in mV will be displayed in the screen or display. ![]() The Multimeter will display the approximate hFE value at the condition of base current 10 A and VCD 2.8V. How to Measure Continuity Audible Buzzer Continuity measurement: Connect the red Test Lead to V mA Jack and the black lead to COM jack. If the resistance is lower than 100 Ohm then there will be buzzer sound which means that continuity is OK.
