2 Safety information
WARNING
Do not measure the current on a circuit when the voltage increases to more
than 600 V. This can cause damage to the instrument and can cause injury to
persons.
WARNING
You must disconnect the test leads from the circuit that you did a test on be-
fore you change the range. If you do not do this, damage to the instrument
and injury to persons can occur.
WARNING
Do not replace the batteries or the fuses before you remove the test leads.
This can cause damage to the instrument and can cause injury to persons.
WARNING
Do not use the device if the test leads and/or the device show signs of dam-
age. Injury to persons can occur.
WARNING
Be careful when you do the measurements if the voltages are more than 25
VAC rms or 35 VDC. There is a risk of shock from these voltages. Injury to per-
sons can occur.
WARNING
Do not do diode, resistance or continuity tests before you have removed the
power from the capacitors and from a device during a test. Injury to persons
can occur.

5.14 Streaming measurement data using Bluetooth
5.14.1 General
Some IR cameras from Flir Systems support Bluetooth communication, and to
those cameras you can stream measurement data from the meter. The data is
then merged into the result table in the IR image.

![](/img.php?id=2083251&img=bg1d.png)
5 Operation
Streaming measurement data is a convenient way to add important information
to an IR image. For example, when identifying an overheated cable connection,
you may want to know the current in that cable.
5.14.2 Procedure
1. Pair the IR camera with the instrument. Refer to the camera manual for infor-
mation on how to pair Bluetooth devices.
2. Turn on the camera.
3. Turn on the meter.
4. Press the on the meter to enable Bluetooth.
5. Choose the variable that you want to use (voltage, current, resistance, etc.).
Results from the meter will now automatically be displayed in the result table
in the top left corner of the IR camera screen.
