Introduction
The Fluke IRR1-SOL Irradiance Meter (the Meter) provides digital read-outs
related to photovoltaic (PV) panels. Measures and reads:
• Solar irradiation (W/m2) on the surface of a photovoltaic (PV) panel
• Temperature (°F or °C) on the surface of a photovoltaic (PV) panel
• Inclination (degrees) of a photovoltaic (PV) panel
• Cardinal degrees with the compass function
The read-outs provided by the Meter help determine optimum positioning of the
photovoltaic (PV) panel for best performance.
Kit Components
The product contains the following items:
1 FLK-IRR1-SOL/001 Solar Irradiance Meter
1 FLK-80PR-IRR External Temperature Probe with Suction Cup
1 C250 Carrying Case with Shoulder Strap
4 AA Alkaline Batteries

Safety Information
A Warning identies hazardous conditions and procedures that are
dangerous to the user. A Caution identies conditions and procedures that
can cause damage to the Product or the equipment under test.
Warning
To prevent personal injury and damage to the Product:
• Read the entire users manual before using the Meter.
• Use the Meter only as described in the Users Manual otherwise
the protection provided by the equipment may be impaired.
• Inspect the Meter before use. Do not use it if it appears damaged.
• Do not use the Meter around explosive gas, vapor, and/or in damp
or wet environments that exceeds IP40.
• The Meter contains no user-serviceable parts. Do not open
the instrument.
• Use only AA batteries, properly installed in the Meter case, to
power the Meter (see Battery Replacement).
• To avoid false readings, replace the batteries as soon as the low
battery indicator appears.
• Remove the batteries if the Meter is not used for an extended
period of time, or if stored in temperatures above 140 °F (60 °C).
If the batteries are not removed, battery leakage can damage the
Meter.
• Have the Meter serviced only by qualied service personnel.

Measuring Temperature and Irradiance
Irradiance and Internal Sensor Temperature Measurements
The Meter can measure irradiance and temperature by simply placing the
meter directly onto the PV panel. The internal, embedded conductive sensor
in the back of the Meter will automatically take the temperature reading.

Temperature can also be taken through the external temperature probe.
Connecting the External Temperature Probe
Attach the temperature probe to the top of the Meter. The screen automatically
shows the icon once connected. The icon indicates that the temperature
is now being read by the external probe. Place the Meter on or beside the PV
panel and connect the suction cup to the underside of the PV panel.

Measuring Inclination and Cardinal Direction
Place the Meter directly onto the PV panel to get accurate tilt.
For surfaces of rooftops with inclinations di󰀨erent than 0°, push the
ZERO button for 2 seconds to reset the angle and measure the true
inclination of a solar panel.
≤90°
N
The compass measurement will require a two-step process for accurate
cardinal direction.
Step 1: Perform irradiance, temperature and inclination measurements with
meter placed on and aligned with the PV panel. The compass function will
show “---” when the tilt angle is above 20 degrees. At a tilt angle of <20
degrees any compass reading shown will be inaccurate due to the inuence
by surrounding metal objects.
Step 2: Perform the compass measurement away from the PV panel by
holding the meter or placing meter on a horizontal surface (0 to 20 degrees
tilt) pointing the tip of the meter in the direction that the PV panel faces. Keep
away from any metal objects.
Note
The compass will reference magnetic north. The compass reading will
be unreliable if the meter is placed on or near objects containing metal
(including solar panels, metal roofs, concrete surfaces with rebar, etc).

Maintenance
Battery Replacement
The battery compartment on the back of the Meter makes it easy to change
the batteries. Use four (4) AA 1.5 V alkaline batteries.
Note: Batteries are not pre-installed in the meter.
1. Make sure that the meter is turned o󰀨.
2. Use a screw driver to unscrew the captive screw.
3. Remove the battery cover.
4. Install batteries.
5. Replace the battery cover and secure it with the provided screw.

Cleaning
Periodically wipe the case with a damp cloth and mild detergent.
Caution
To prevent damage to the Meter:
• The Meter contains no user-serviceable parts. To avoid injury, or
damage to the Meter, do not open the case.
• To avoid damaging the Meter, do not use abrasives or solvents to
clean the Meter case.
Storage
During longer periods of non-use (>60 days), remove and store the
battery separately.
Service and Parts
Only a qualied technician should service the Meter. For service information,
contact your nearest Fluke dealer or service center.
