5. Basic Operation and Features
5.1 Powering the Meter
1. Set the function switch to any position to switch on the meter.
2. If the battery status indicator appears low or if the meter does not power on,
replace the two (2) ‘AAA’ batteries. See Section 12.2, Battery Replacement.
5.2 Intelligent Auto Power OFF (APO)
The meter will intelligently avoid entering the APO mode under normal measurement
conditions. The APO feature turns the meter off automatically, in order to extend
battery life, after approximately 32 minutes if none of the conditions below are met:
1) Rotary switch or push button operation
2) Significant measurement value (reading above 8.5% of the range)
3) Non-OL readings for Resistance, Continuity or Diode function
4) Non-zero readings for Hz function
5) Electric field signal present for EF NCV function
To wake the meter from APO, short press the MODE button, or turn the rotary switch
OFF and then back on. Always turn the rotary switch to the OFF position when the
meter is not in use.
5.3 LCD Backlight
Long press the backlight button to toggle the LCD backlight ON and OFF. The
backlight will automatically switch OFF after 10 minutes to conserve battery energy.
5.4 Auto/Manual Range Mode
For most auto-ranging functions, short press the RANGE button to select manualranging override. The meter will remain in the range it was in and the auto range
display icon will switch off. Short press the button again to select the next range. Long
press the button to resume auto-ranging. Note: Manual-ranging is not available for
Auto-V, Capacitance & Hz functions.
5.5 True RMS Response
True RMS (Root Mean Square) allows the meter to respond accurately to the effective
RMS value, regardless of the waveform shape (square, saw-tooth, triangle, pulse,
spike, as well as distorted waveforms with the presence of harmonics).
5.6 Crest Factor
Crest Factor is the ratio of the Crest (instantaneous peak) value to the True RMS value.
A pure sine wave has a Crest Factor of 1.414. A badly distorted sinusoidal waveform
normally has a much higher Crest Factor.
5.7 Out-of-range Warning (O.L)
If the input is over/under the full-scale range in Manual range mode, or if the signal
has exceeded the maximum/minimum input in Auto range mode, ‘O.L’ is displayed.

5.8 Data Hold
In Data Hold mode, the displayed reading is held. To enter/exit Data Hold mode, short
press the button. In Hold mode, the indicator is displayed.
5.9 Relative Zero Mode
Relative Zero allows the user to offset measurements by the amount determined by a
stored reference value. Almost any displayed reading can be set as the relative
reference value including MAX/MIN/AVG readings. Long press the button to toggle
Relative Zero mode ON and OFF.
When switched ON, the meter stores the displayed reading as the offset/reference
value, the zero (0) symbol appears on the upper right, and the meter will display the
measurement value minus the stored reference.
5.10 VFD Mode (Low Pass Filter) Models DM64/DM66 only
The VFD (variable-frequency drive) utility eliminates high-frequency noise from AC
voltage measurements. This is accomplished using a low-pass filter. To activate, short
press the MODE button until the VFD symbol appears.
5.11 MAX-MIN-AVG Record Mode
Short press REC to activate the recording mode, three arrow icons ( [MAX],
[MIN], and [AVG]) will appear indicating that the meter is now recording. Short
press the REC button to step through the MAX-MIN-AVG readings. The meter beeps
when new MAX or MIN readings are detected. Long press REC to exit the recording
mode. Auto-ranging is active and Auto-Power-Off is disabled in this mode.
5.12 Test Lead Input Warning
The meter beeps (at a fast rate) as well as displays “InEr” to warn the user that an
improper connection to the A, mA, or A input jack is being made when another
function, especially a voltage function, is selected.
5.13 Auto Voltage AC/DC Detection in ‘Lo Z’ mode (DM64/DM66 only)
Auto Voltage ‘Lo Z’ mode automatically selects DCV or ACV, based on input levels
detected through the test leads. This mode uses a ‘Lo Z’ low ramp-up impedance
(approx. 2.1kΩ for low voltages) to drain ghost voltages. Refer to Section 6.2 Low
Impedance Auto-Voltage Measurements for complete details.
FLIR DM6x USER MANUAL Document Identifier: DM6x-en-US_AA

6. Measurements
Caution: Before and after hazardous voltage measurements, test the voltage function on a known
source such as line voltage to determine proper meter functioning.
Caution: Before operating the device, you must read, understand, and follow all instructions,
dangers, warnings, cautions, and notes.
Caution: When the meter is not in use, the function switch should be set to the OFF position.
Caution: When connecting the probe leads to the device under test, connect the COM (negative)
lead before connecting the positive lead. When removing the probe leads, remove the positive
lead before removing the COM (negative) lead.
6.1 AC/DC Voltage Measurements (VFD and Frequency on DM64/DM66)
Move the rotary switch to the position and short press the MODE button to step
through the following modes: DCV, ACV, and ACV with VFD*. The last selection will be
saved as the power-up default. For AC, short press the Hz button to view the frequency*
and press again to return to the voltage measurement (refer to Section 6-3 for more on
Frequency measurement features). Refer to Fig. 6-1 for function switch position, test
lead connection, push-button operation, and display example.
*VFD and Frequency available on models DM64/DM66 only
Figure 6-1 – ACV, DCV, and VFD application diagram
Notes: VFD-ACV and the associated Hz measurement are equipped with a digital low-
pass filter, and are capable of handling VFD (Variable Frequency Drives) signals for
fundamental V & Hz readings. It also improves ACV and Hz reading stability when being
used in noisy electrical environments.
FLIR DM6x USER MANUAL Document Identifier: DM6x-en-US_AA
14
6.2 Low Impedance (Lo Z) Auto-Voltage Measurements (DM64/66 only)
Auto Voltage Lo Z mode automatically selects DCV or ACV, based on input levels
detected through the test leads. This mode uses a ‘Lo Z’ low ramp-up impedance
(approx. 2.1kΩ for low voltages) to drain ghost voltages*. Refer to Fig. 6-2 for function
switch position, test lead connection, and display example.
Figure 6-2 – LoZ application diagram
With no input, the meter displays “- - - -” when it is ready for testing.
When a signal above the voltage threshold of 8.0V DC or 5.5V AC (up to the rated
600V) is present, the meter displays the voltage value in DC or AC, whichever is larger
in peak magnitude. Attempting to measure ‘Lo Z’ voltages below these limits will
result in the same readings as for the normal voltage measurement mode.
Notes:
*Ghost-voltages are unwanted stray signals, coupled from adjacent live signals, which can confuse
common Multimeter voltage measurements. This feature is helpful when distinguishing between
hot and open wires (to ground) in electrical installations, for example. Only HOLD, EF (NCV) &
Backlight push-button features are available in Auto Voltage mode.
WARNING:
Lo Z Auto Voltage mode input impedance increases abruptly from the initial 2.1kΩ to a few
hundred kΩ’s on high voltage hard signals. “Lo Z” appears on the LCD as a reminder. Peak initial
load current, while probing 1000VAC for example, can be as high as 673mA (1000V x 1.414 /
2.1kΩ), decreasing abruptly to approx. 2.4mA (1000V x 1.414 / 580kΩ) within a fraction of a
second. Do not use this feature on circuits that could be damaged by such low input impedance.
Instead, use the high input impedance voltage modes to minimize loading on such circuits (rotary
switch set to the position).
FLIR DM6x USER MANUAL Document Identifier: DM6x-en-US_AA

6.3 Line Frequency Measurements (DM64/DM66 only)
Short press the Hz button to toggle the frequency function ON and OFF. Refer to Fig. 6-3
for function switch position, test lead connection, push-button operation, and display
example. A voltage application is shown in Fig. 6-3, but line frequency can also be viewed
in AC Current applications; however, the input sensitivity adjustment, as detailed below,
applies to AC Voltage applications only.
Figure 6-3 – Line Frequency Measurements (Hz) for ACV/VFD
Note on Input Sensitivity for voltage applications:
Input sensitivity varies automatically with the range selected. The 6V range has the highest
sensitivity and the 1000V range has the lowest. In the DCV, ACV or VFD-ACV voltage functions, the
trigger voltage will be displayed immediately before starting the Hz measurement. While displayed,
short press the RANGE button to manually select another trigger voltage range (voltage modes
only). First measure the signal voltage (or current) level and then activate the Hz function in that
range to find the optimum trigger level. If the Hz reading becomes unstable, select a lower
sensitivity to avoid electrical noise. If the reading shows zero, select a higher sensitivity.

6.4 Resistance and Continuity Measurements
Warning: Do not perform resistance or continuity tests before removing power from
capacitors and other devices under test during a measurement. Injury to persons can
occur.
Short press the MODE button to toggle Resistance and Continuity functions. The last
selection will be saved as the power-up default. Refer to the Fig. 6-4 for function switch
position, test lead connection, push-button operation, and display examples.
Figure 6-4 – Resistance and Continuity Measurements
For convenience, the Continuity function offers a continuous beep tone together
with a flashing LCD backlight indicating a complete wire. This audio-visual indication is
especially handy in noisy work environments. If the resistance is < 30Ω the meter beeps.
If the resistance is > 480Ω the meter will not beep. If the resistance is > 30Ω but < 480Ω
the beeping will stop at an unspecified point.
CAUTION
Be sure to remove power from any circuit or device before measuring resistance and
continuity. Measuring resistance and continuity on a live circuit will produce false results
and may damage the instrument.

In the Diode mode, the normal forward voltage drop (forward biased) for a good silicon
diode is between 0.400V to 0.900V (Fig 6-6, left). A reading higher than that indicates a
leaky diode (defective). A zero reading indicates a shorted diode (defective). An OL
display indicates an open diode (defective). Reverse the test lead connection (reverse
biased) across the diode (Fig 6-6, right). The digital display shows OL if the diode is good.
Any other readings indicate that the diode is resistive or shorted (defective).
