IRR2-BT

Solar Irradiance Meter Pro

Users Manual

Introduction

The Fluke IRR2-BT Solar Irradiance Meter Pro (the Meter or

Product) provides digital measurements related to photovoltaic

(PV) panels.

The Meter 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 Meter can wirelessly transfer measurements to the

SMFT-1000 PV Analyzer (the Analyzer). This data is used for

IV curve performance analysis of the solar panel and other

measurements of the roof slope and the compass.

Note

The Meter does not connect to smart phones and other

smart devices.

When the date and time on the Meter and the Analyzer match and

the Meter is out of wireless connection range with the Analyzer,

the Meter automatically records the data to memory. This data

can be transferred later to the SMFT-1000.

Operation

Use the Analyzer to adjust the recording settings, memory, and

clock synchronization. See SMFT-1000 Users Manual for more

information.

1. Power ON/OFF

At power on, the Meter shows the available memory in hours

for 2 seconds. The total memory capacity allows continuous

recording for 17 hours. Partial memory records for less time.

The display shows the Irradiance/Temperature mode

2 seconds after power up.

2. Move the Meter within wireless range of the main Analyzer.

The range is up to 50 m (150 ft) with a clear line-of-sight view

(no sight obstruction).

shows on the display when the Meter has wireless

connection to the Analyzer.

Note

If already installed on the roof, it is not necessary to

move the Meter. Instead, move the Analyzer near the

building to establish the connection. When connection is

established, you can synchronize both units from the

ground.

3. When connected, the Analyzer sends the command to the

Meter for synchronization, shows on the display.

The Meter automatically starts recording the irradiance and

temperature data and REC shows on the display until the

memory is full.

When the Meter is not synced, blinks on the display and

REC turns off.

should not blink at any point. For more information about

wireless connection, see the SMFT-1000 Users Manual.

When the memory on the Meter is full:

REC is off

turns ON

blinks on the display to indicate that the data cannot

download to the Analyzer

Irradiance and Internal Sensor Temperature

Measurements

To measure irradiance and temperature, install the Meter and the

bracket on the solar panel.

Note

For a spot check measurement, position the Meter

directly on the PV panel. The internal, embedded

conductive sensor in the back of the Meter automatically

takes the temperature reading.

The external temperature probe also takes temperature

measurements.

External Temperature Probe Connection

Connect the temperature probe to the top of the Meter. The

screen automatically shows when connected. The icon

indicates that the temperature is now read by the external probe.

Place the Meter on or beside the PV panel and connect the

temperature probe with the suction cup to the underside of the

PV panel. Secure the temperature probe to the panel with

electrical tape.

Inclination and Cardinal Direction

Place the Meter directly onto the PV panel to get accurate tilt. For

surfaces of rooftops with inclinations different than 0°, push

for 2 seconds to reset the angle and measure the true inclination

of a solar panel. Secure a probe to the solar panel with optional

electrical or similar tape to assure reliable mounting.

The compass measurement requires a two-step process for

accurate cardinal direction.

1. Do irradiance, temperature, and inclination measurements with

Meter placed on and aligned with the PV panel. The compass

function shows --- on the LCD 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 by

surrounding metal objects.

2. Do the compass measurement away from the PV panel by

holding the meter or placing meter on a horizontal surface

(0 degrees 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 measurement is in reference to magnetic

north. The measurement is unreliable if the Meter is

placed on or near objects containing metal (such as solar

panels, metal roofs, and concrete surfaces with rebar).

Compass Calibration

The Product contains a compass. The compass is affected by

metal in the environment.

Always recalibrate the compass:

Before the first use.

Each time you change the batteries.

When you change geographical locations.

When there is a significant change in the environment, for

example, new metal fittings.

1. Do the calibration outdoors, at least 2 m (6 ft) away from any

metal objects.

2. Push and hold the Switch button as you power on the Product

to enter compass calibration mode. The Product shows CAL

and the compass icon.
