Using the Features (cont'd)
Disabling the Beeper:
disable the beeper feature. Turn the selector to OFF and then back on to enable the beeper.
DM-510A Only
Low Impedance AutoCheck™ Mode:
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.
Range-Lock and Function Feature: While in the AutoCheck™ mode, press the SELECT button
momentarily to lock the displayed function. Press the RANGE button momentarily to lock the dis-
played measurement range. Press either button repeatedly to step through the ranges or functions.
Energized Circuit Alert: If the resistance mode is locked in the AutoCheck™ mode and the leads
are placed across an energized circuit, the meter will emit an audible warning tone.
REC:
Press momentarily to activate the MAX/MIN recording mode. The input value is measured
every 50 ms in this mode. "MAX MIN" will appear on the display. The LCD will display the actual
input value. The meter will beep whenever the maximum or minimum is updated. Press repeatedly to
select the desired display: maximum, minimum, or actual input. Press and hold to exit this mode.
The automatic power off feature is disabled when using this function.
CREST:
Press momentarily to activate the crest recording mode. The input value is measured every
5 ms in this mode.
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.
Hold down the RANGE button while turning the meter on to temporarily
In this mode, the meter automatically selects the proper
and "MAX" will appear on the display. The LCD will display the maximum crest
