How to use Reed Handheld Digital Multimeters (ST-118)

Non-Contact AC Voltage Measurements
Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet. If AC voltage is present, the detector light will illuminate. The conductors in electrical cord sets are often twisted. For best results, rub the probe tip along a length of the cord to assure placing the tip in close proximity to the live conductor. The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sensor. This is normal operation.

AC/DC voltage measurements
Set the function switch to the green V position. Press the MODE button to indicate “DC” or “AC” on the display. 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. Read the voltage in the display.

AC/DC current measurements
Set the function switch to the µA/mA position. For current measurements up to 2000µA DC/AC, set the function switch to the mA position. Press the MODE button to indicate “DC” / “AC” on the display. 4. 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. Read the current in the display.

Resistance measurements
Set the function switch to resistance check the position. 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 measurements
Set the function switch to the continuity check position. Press the MODE button to indicate on the display. Touch the test probe tips to the circuit or wire you wish to check. If the resistance is less than approximately 150O, the audible signal will sou
