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.
#T559824; r.8007/8011; en-US 22
Final before translation
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.

6 Maintenance
6.1 Cleaning and storage
Clean the meter with a damp cloth and mild detergent; do not use abrasives or
solvents.
If the meter is not to be used for an extended period, remove the batteries and
store them separately.
6.2 Battery replacement
1. To avoid electrical shock, disconnect the meter if connected to a circuit, re-
move the probe/thermocouple leads from the terminals, and set the function
switch to the position before attempting to replace the batteries.
2. Unscrew and remove the battery compartment cover.
3. Replace the six standard AAA batteries, observing correct polarity.
4. Secure the battery compartment cover.
6.3 Fuse replacement
The fuses are accessed via the battery compartment cover.
Only use recommended fuses, see section 7 Technical specifications, page 25.
