• Low Impedance AutoCheck™ Mode: In this mode, the meter automatically selects the proper measurement based on the input.

• If there is no input, “Auto” appears on the display.

• If the voltage is above approximately 1 volt AC or DC, voltage is displayed.

• If both AC and DC voltages are present, the larger voltage is displayed.

• If no voltage is present and there is resistance less than approximately 10 MΩ, resistance is displayed. If the measured resistance is below the continuity threshold (between 10 Ω and 80 Ω), then the continuity tone will sound. This mode features low input impedance to mask stray or “ghost” voltage pickup. The input imped- ance is approximately 2.5 kΩ at low voltage, increasing to approximately 375 kΩ at 1000 V. The symbol “LoZ” indicates that the meter is in a low impedance mode. Do not use the AutoCheck™ mode on circuits that could be damaged or activated by such low input impedance. Instead use the selector to select the high impedance AC or DC volts modes to minimize loading for such circuits.

The LCD will display the maximum crest value. Press repeatedly to select the desired display: maximum or minimum crest value. Press and hold to exit this mode. Automatic ranging and automatic power off are disabled when using this function. Using the Features (cont’d)10 AC Measurement AC measurements are usually displayed as RMS (root mean square) values. The RMS value is equal to the value of a DC waveform, which would deliver the same power if it replaced the time-varying wave- form. Two AC measurement methods are average-responding RMS calibrated and true RMS-reading. The average-responding RMS calibrated method takes the average value of the input signal after full wave rectification, multiplies it by 1.11, and displays the result. This method is accurate if the input signal is a pure sine wave. The DM-200A and DM-210A are average-responding meters. The true RMS-reading method uses internal circuitry to read the true RMS value. This method is accu- rate, within the specified crest factor limitations, whether the input signal is a pure sine wave, square wave, triangle wave, half wave, or signal with harmonics. The ability to read true RMS provides much more measurement versatility. The DM-510A is a true RMS meter. The Waveforms and Crest Factors table shows some typical AC signals and their RMS values.

• The crest factor is the ratio of the peak value to the RMS value; it is represented by the Greek letter x.DM-200A • DM-210A • DM-510A
