Multimeter's-ல் நமக்கு தெரியாமல் இருக்கும் சில முக்கியமான options-ஐ பற்றி தெரிந்து கொள்ள வேண்டியவை ! HD

OPERATING INSTRUCTION DC CURRENT MEASUREMENT Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.Set the range switch to the desired A range.Open the circuit in which the current is to be measured, and connect the test leads in series with the circuit. Read the current value on the LCD display along with the polarity of the red test lead. DC VOLTAGE MEASUREMENT Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.Set the range switch to the desired Vrange. If the voltage is not known beforehand, set the range switch at the highest range position and then reduce it range by range until satisfactory resolution is obtained.Connect the test leads across the device or circuit to be measured. Read the voltage value on the LCD display along with the polarity of the red test lead. AC VOLTAGE MEASUREMENT Connect the red test lead to the jack and the black test lead to the "COM" jack.Set the range switch to the desired Vrange. Connect test leads across the device or circuit to be measured and read the voltage value on the LCD display. RESISTANCE MEASUREMENT Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack. Set the range switch to the desired Ω range.If the resistor to be measured is connected to a circuit, disconnect circuit power and discharge all capacitors before measuring resistance.Connect the test leads across the resistor to be measured and read the resistance value on the LCD display. TEMPERATURE MEASUREMENT Set the range switch to the "TEMP" range, and the meter will show the current room temperature without any external thermocouple connections.Connect the K type thermocouple to the and "COM" jacks. Contact the object to be measured with the thermocouple carefully.Read the temperature value on the LCD display. TRANSISTOR TEST 1. Set the range switch to the "hFE" range.Determine whether the transistor to be tested is PNP or NPN type and locate the emitter, base, collector leads.Insert the leads into the proper holes of the hFE socket on the front panel.The meter will display the approximate hFE value. DIODE & CONTINUITY MEASUREMENT Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.Set the range switch to the range. Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode of the diode.The approximate forward voltage drop of the diode will be displayed in mV. If the connection is reversed, only figure "1" will be shown on the LCD.Connect the test leads to the two terminal of the circuit to be tested. If the resistance is lower than about 50 Ω, the built-in buzzer will sound. TEST SIGNAL OUTPUT Set the range switch to or range.A test signal will appear between the and "COM" jacks. The voltage is approximate 5Vp-p. A coupling capacitor should be used when connecting the meter to a circuit. BATTERY MEASURE
