Irradiance Meter
Users Manual

Introduction

The Fluke IRR1-SOL Irradiance Meter (the Meter) provides digital read-outs related to photovoltaic (PV) panels. Measures and reads:
• Solar irradiation (W/m 2 ) 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 the optimum positioning of the photovoltaic (PV) panel for best performance.

Safety Information

A Warning identifies hazardous conditions and procedures that are dangerous to the user. A Caution identifies 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 user’s 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 exceed 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 qualified service personnel?

Operation

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 an accurate tilt.
For surfaces of rooftops with inclinations different than 0°, push the
ZERO buttons for 2 seconds to reset the angle and measure the true inclination of a solar panel.

The compass measurement will require a two-step process for accurate cardinal direction.
Step 1: Perform irradiance, temperature, and inclination measurements with a 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 influence of surrounding metal objects.
Step 2: Perform the compass measurement away from the PV panel by holding the meter or placing the 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 off.
2. Use a screwdriver 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 qualified technician should service the Meter. For service information, contact your nearest Fluke dealer or service center.
