How to use True RMS Measuring Instrument R5010 (was ST-9919)

DC Voltage Measurement

Set the function switch to the green VDC position. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit and read the voltage on the display. Please note that ALWAYS turn the function switch to the OFF position when the meter is not in use.

AC Voltage (Frequency, Duty Cycle) Measurement
Set the function switch to the green VAC/Hz/% position. Insert the black test lead banana plug into the negative COM jack adn red test lead banana plug into the positive V jack. Touch the black test probe tip to the neutral side of the circuit and the red test probe tip to the “hot” side of the circuit. Read the voltage in the display. Press the MODE button to indicate “Hz” and read the frequency in the display. Press the MODE button again to indicate “%”. Read the % of duty cycle in the display.

DC Current Measurement
Insert the black test lead banana plug into the negative COM jack. For current measurements up to 4000µA DC, set the function switch to the yellow µA position and insert the red test lead banana plug into the µA/mA jack.For current measurements up to 400mA DC, set the function switch to the yellow mA position and insert the red test lead banana plug into the µA/mA jack.For current measurements up to 20A DC, set the function switch to the yellow 10A/HZ/% position and insert the red test lead banana plug into the 10A jack.Press the MODE button to indicate “DC” on the display. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit Apply power to the circuit and read the current in the display

AC Current (Frequency, Duty Cycle) Measurement
Insert the black test lead banana plug into the negative COM jack. For current measurements up to 4000µA AC, set the function switch to the yellow µA position and insert the red test lead banana plug into the µA/mA jack. For current measurements up to 400mA AC, set the function switch to the yellow mA position and insert the red test lead banana plug into the µA/mA jack. For current measurements up to 20A AC, set the function switch to the yellow 10A/HZ/% position and insert the red test lead banana plug into the 10A jack. Press the MODE button to indicate “AC” on the display. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current. Touch the black test probe tip to the neutral side of the circuit Touch the red test probe tip to the “hot” side of the circuit. Apply power to the circuit and read the current in the display
Press and hold the MODE button to indicate “Hz”. Read the frequency in the display. Momentarily press the MODE button again to indicate “%”. Read the % duty cycle in the display. Press and hold the MODE button to return to current measurement

Resistance Measurement
Set the function switch to the green O CAP position. Insert the black test lead banana plug into the negative COM jack Insert the red test lead banana plug into the positive O jack. Press the MODE button to indicate “O” on the display. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading. Read the resistance in the display.

Continuity Check
Set the function switch to the green O CAP position. Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive O jack. Press the MODE button to indicate and O on the display. Touch the test probe tips to the circuit or wire you wish to check. If the resistance is less than approximately 35O, the audible signal will sound. If the circuit is open, the display will indicate “OL”.

Diode Test
Set the function switch to the green O CAP position. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. Press the MODE button to indicate and V on the display. Touch the test probes to the diode under test. Forward voltage will typically indicate 0.400 to 0.700V. Reverse voltage will indicate “OL”. Shorted devices will indicate near 0V and an open device will indicate OL in both polarities.

Temperature Measurement
Set the function switch to the green Temp position. Insert the Temperature Probe into the input jacks, making sure to observe the correct polarity. Press the MODE button to indicate ºF or ºC. Touch the Temperature Probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes (about 30 seconds). Read the temperature in the display Note: The temperature probe is fitted with a type K mini connector. A mini connector to banana connector adaptor is supplied for connection to the input banana jacks.

Capacitance Measurement
Set the rotary function switch to the green O CAP. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive V jack. Press the MODE button to indicate F. Touch the test leads to the capacitor to be tested. Read the capacitance value in the display.

Frequency (Duty Cycle) Measurement (Electronic)
Set the rotary function switch to the green Hz/% position. Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive Hz jack. Touch the test probe tips to the circuit under test. Read the frequency on the display. Press the MODE button to indicate “%”. Read the % duty cycle in the display

% 4 – 20mA Measurement
Set up and connect as described for DC mA measurements. Set the rotary function switch to the 4-20mA% position. The meter will display loop current as a % with 0mA=-25%, 4mA=0%, 20mA=100%, and 24mA=125%.
