- Page 12 DC+AC True RMS DC+AC True RMS calculates both of the AC and DC components given by the expression when making measurement, and can responds accurately to the total effective RMS value regardless of the waveform. Distorted waveforms with the presence of DC components and harmonics may cause: 1) Overheated transformers, generators and motors to burn out faster than normal...
- Page 13 Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. It is excellent in detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments. Default Functions The Multimaster™ will set the function last used as the default function. For example, if dBm is last used in the VAC position, the meter will display dBm the next time that function is selected.

Page 14: Operation
Operation Measurement Considerations NOTICE: Read and understand all warning and caution statements listed in the safety section of this operation manual prior to using this meter. 1. Always move the rotary function switch to the OFF position when the meter is not in use. This meter has Auto Power OFF that automatically shuts the meter OFF if 17 minutes elapse without activity. - Page 15 2. For current measurements up to 5000µA, set the function switch to the "µA" position and insert the red test lead into the mA-µA jack. 3. For current measurements up to 500mA, set the function switch to the "A/mA" position and insert the red test lead into the mA-µA jack. 4.
- Page 16 6. For Continuity tests, if the resistance is less than the threshold (20Ω to 200Ω), an audible tone will sound.
- Page 17 Capacitance Measurements 1. Insert the black lead into the negative COM jack and the red test lead into the positive CAP jack. 2. Set the function switch to the " CAP" position. 3. Press the SELECT key momentarily to select Capacitance 4.
- Page 18 Diode Test 1. Insert the black lead into the negative COM jack and the red test lead into the positive CAP jack 2. Set the function switch to the " CAP" position. 3. Press the SELECT key momentarily to select the diode function 4.
- Page 19 Relative mode Relative Zero allows the user to offset the meter by using the displayed value as the zero reference value. Practically all of the displayed readings can be set as the relative reference value including the MAX/MIN recording feature. Press the key momentarily to activate and to exit Relative Zero mode.
- Page 20 RS-232 PC Interface This instrument is equipped with an optically isolated interface port (located on the rear of the meter). An optional Windows software and interface package is available for data acquisition applications. This optional kit is required to connect the meter to a PC. The software provides digital, analog, and graphical data displays.
