A digital multimeter is a convenient measuring instrument that allows by itself the measurement of DC voltage, AC voltage, DC current, AC current and resistance (Pocket type DMM normally cannot be used for the measurement of current for safety reasons). In addition to these basic measuring functions, most models are provided with features such as a diode test function and con­tinuity buzzer. Some of recent products feature the measure­ment of frequency and capacitor capacity. Some have added functions of maximum and minimum value hold and relative val­ue measurement as well as data hold and range hold functions. The advent of DMMs (PC series) connectable to a PC makes it possible to let a PC assume the function of expensive recording meters and recorders.

Highly accurate measurement. Higher accuracy (1% or less) compared with an analog multimeter (approximately 3%).

Voltage, Resistance measurement

Choose the necessary functions, except voltage and resistance measurement, (including need for the measurement of current (400mA, 10A, 12A, 20A), ca­pacitor, frequency, temperature and measurement of 4-20mA, etc.)

Functions required differ depending on where the measurement is taken.

1) To record measured values concurrently with the process of measurement

To fix data by the data hold function. To secure the test lead in the holster.

2) To check changes in measured values

Measurement of maximum values, minimum val­ues, and relative values.

In measuring distorted sine and non-sine waves (sq­uare wave, triangular wave, pulse), significant errors occur in measurement by models making measure­ments by mean values.

AC-Coupled true RMS value: Adapted to measure­ments of distorted sine and non-sine waves of the AC AC + DC-coupled true RMS value: Adapted to meas­urements of waveform containing a DC component.

There are other types including a function to transfer data during measurement to a PC in real time and a function to record measured data in a built-in memory. To transfer data to a PC, optional connecting cables and data retrieval software (PC Link or PC Link Plus) are required in addition to a DMM of PC series.

In making measure­ments, connect your DMM in parallel with an object to be measured. Do not apply signals ex­ceeding the maxi­mum rated input vol­tage.

Current measurement

In making measure­ments, connect your DMM in series with an object to be measured. Do not apply signals exceeding the maxi­mum rated input cur­rent.

When the black test lead is connected to the cathode side of the diode and the red test lead to the anode side, the forward voltage can be measured. In contrast, if the black test lead is connected to the anode side of the diode and the red test lead to the cath­ode side, the reverse voltage can be meas­ured and "OL" display appears.
