Operation General Procedures 1. Apply power via ON/OFF switch. If the low battery symbol appears, replace the battery. 2. Set the function switch to the correct position before taking measurements. 3. Press the Display Release Button and set the display to a convenient viewing angle. AC/DC Voltage Measurements (DO NOT EXCEED MAX INPUT LIMIT OF 1000VDC) 1. Connect the black test lead to the meter's COM socket and the red lead to the meter's "VΩF" socket. 2.
Diode Measurements 1. Connect the black test lead to the COM-socket and the red lead to the VΩ socket. 2. Set the rotary switch to the "Diode" symbol position 3. Connect the test leads to the diode under test. 4. The value of the forward voltage drop (0.3 to 0.6V) or the open circuit voltage (2.6V approx.) will appear in the LCD display for a good diode. AC/DC Current Measurements (If the magnitude of current is unknown, select the highest meter range and then reduce the range as needed) 1.
Continuity Measurements (Remove power or voltage from the device under test) 1. Connect the black test lead to the COM-socket and the red lead to the VΩ socket. 2. Set the rotary switch to the "Continuity" symbol position 3. The continuity buzzer will sound if the measured resistance is < 30Ω Battery Measurements (MV-110 only) 1. Connect the black test lead to the COM-socket and the red lead to the VΩ socket. 2. Set the rotary switch to the 1.5V or 9V position 3.
Temperature Measurements (MV-120 only) 1. Insert the type K thermocouple mini-connector into the "K" socket. 2. Set the rotary switch to the ºF or ºC position. 3. The value of the measured temperature will appear in the LCD. Transistor hFe Measurements 1. Move the rotary select switch to the hFe position 2. Plug the transistor under test into the appropriate transistor input jacks on the meter front. 3. For transistor types PNP and NPN, the meter has matching input sockets.
