2. Safety
Safety Notes
•Before operating the device, you must read, understand, and follow all instructions,
dangers, warnings, cautions, and notes.
•FLIR Systems reserves the right to discontinue models, parts or accessories, and other
items, or to change specifications at any time without prior notice.
•Remove the batteries if the device is not to be used for an extended period.
Warning Statements
•Do not operate the device if you do not have the correct knowledge. Incorrect operation
of the device can cause damage, shock, injury, or death to persons.
•Do not start a measuring procedure before you have set the function switch to the
correct position. Failure to do so can cause damage to the instrument and can cause
injury to persons.
•Before each use, verify tester operation by measuring a known voltage.
•Do not change to the resistance mode when measuring voltage. This can cause damage
to the instrument and can cause injury to persons.
•Do not measure the current on a circuit when the voltage increases to more than 1000 V.
This can cause damage to the instrument and can cause injury to persons.
•Do not make 10A current measurements for longer than 10 seconds at a time; further,
allow a buffer of 15 minutes between each measurement. 10A current measurements
which exceed 10 seconds may cause damage to the meter and/or test leads.
•You must disconnect the test leads from the circuit under test before you change the
range. Failure to observe this warning can damage the instrument and cause bodily
injury.
•Do not replace the batteries before you remove the test leads. This can cause damage to
the instrument and can cause injury to persons.
•Do not use the device if the test leads and/or the device show signs of damage. Injury to
persons can occur.
•If the insulation on a probe (test lead) is damaged, replace with a new one that meets or
exceeds the IEC 61010-031 standard.
•Be careful performing measurements if the voltages are > 25 VAC rms or 35 VDC. There is
a risk of shock from these voltages. Injury to persons can occur.
•Do not do diode, resistance, or continuity tests before you have removed the power from
capacitors and other devices under test. Injury to persons can occur.
•Be careful when performing voltage checks on electrical outlets. These checks are
difficult because of the uncertainty of the connection to the recessed electrical contacts.
You must not rely solely on this device when determining if the terminals are not “live”.
There is a risk of electrical shock. Injury to person can occur.
•Do not touch expired/damaged batteries without gloves. Injury to persons can occur.
•Do not cause a short circuit of the batteries. This can cause damage to the instrument
and can cause injury to persons.

•Do not put the batteries into a fire. Injury to persons can occur.
•Use extreme caution when the laser pointer is on.
•Do not point the beam toward anyone's eye or allow the beam to strike the eye from a
reflective surface.
•Do not use the laser near explosive gases or in other potentially explosive areas.
•Refer to the safety statements below for critical safety information.
Cautions
Do not use the device in a manner not specified by the manufacturer. This can cause damage to
the protection provided.
This symbol, adjacent to another symbol or terminal, indicates that the user
must refer to the user manual for further information.
This symbol, adjacent to a terminal, indicates that, under normal use, hazardous
voltages may be present.
Double insulation.

4.2 Function Switch Positions
Detect AC voltage through the non-contact sensor at the top of the meter.
Measure voltage through the probe inputs with a low-impedance load
positioned across the inputs that stabilizes the measurement.
FLEX Direct: Auxiliary channel for use with optional Flexible Current clamp or
standard clamp adaptors when > 600A measurements are required. In this
mode, the meter will display true rms ACA measurements from the connected
device. Frequency (Hz) can be displayed by pressing the MODE button.
Meter is switched OFF and in full power-saving mode.
Measure AC or DC voltage (V) through the probe inputs. Use the MODE button
to select or AC, Frequency, or DC.
Measure low voltage (mV) through the probe inputs. Use the MODE button to
select AC or DC voltage.
Measure temperature with a thermocouple through the probe inputs using a
thermocouple adaptor (supplied).
Measure resistance, continuity, capacitance, or diode through the probe
inputs. Use the MODE button to select the desired function.
Measure
µA
current through the probe inputs. Use the MODE button to select
AC or DC.
Measure mA current through the probe inputs. Use the MODE button to select
AC or DC.

5. Meter Power
5.1 Powering the Meter
The meter is powered by the supplied TA04 rechargeable battery. Two are provided, so
you can charge one while the other is in use. The battery is inserted in the rear battery
compartment. The compartment is behind the tilt stand, secured by a rotating lock.
Use a screwdriver or a coin to lock and unlock the compartment.
Fig. 5.1 Battery Compartment Lock
Move the function switch from the OFF position to switch the meter on. If the battery
indicator shows that the battery voltage is low, if a low battery screen appears (Fig.
5.2), or if the meter does not power on, replace the TA04 battery with a fully charged
one. See Section 13.2, Battery Replacement.
Fig. 5.2 Low Battery Alert
5.2 Auto Power OFF (APO)
The DM286 has separate APO settings for the meter and worklight. The APO time for
each is selected in the Settings menu (refer to Section 7.2.3.5).
