Page 16: Irradiance Measurements
Irradiance Measurements Irradiance is a measure of light intensity in units of W/m (watts per meter squared). 1. Switch the meter ON. 2. The meter powers up in the Irradiance/Temperature mode. Press the Irra- diance button to return to this mode from other modes. 3. -
Page 17: Temperature Measurements
Temperature Measurements The meter measures the solar panel’s surface temperature in degrees C or F using the embedded temperature sensor or the external temperature probe (supplied). 6.1 Embedded Temperature Sensor 1. Switch the meter ON. 2. The meter powers up in the Irradiance/Temperature mode. Press the Irra- diance/Temperature button to return to this mode from other modes. -
Page 18: External Temperature Probe
Temperature Measurements 6.2 External Temperature Probe 1. Switch the meter ON. 2. The meter powers up in the Irradiance/Temperature mode. Press the Irra- diance/Temperature button to return to this mode from other modes. 3. Connect the external probe to the meter, as shown in Fig. 6.2. 4. -
Page 19: Inclination Angle
Figure 7.1 Ensure a level surface when performing a zero degree calibration. 7.2 Inclination Angle Measurements The PV78 has an internal inclination sensor that measures the solar panel’s tilt angle in degrees. Place the meter, face up, on the surface of the panel, and secure with electri- cal tape, if necessary. -
Page 20: Compass Heading
Compass Heading 8.1 Compass Considerations The PV78 has an internal compass that senses geomagnetic north for refer- ence orientation. If the meter is placed near metallic objects, the sensor will become disoriented. Take compass readings at least 6.6 ft. (2 m) away from metal objects including solar panels, metal roofs, reinforced concrete surfa- ces, and electronic equipment. -
Page 21: Compass Calibration
Compass Heading 8.3 Compass Calibration Calibrate the meter often, especially if it has not been used recently or if it is being used in a new location. Figure 8.2 Slowly rotate the meter 360 degrees on a horizontal plane for at least one minute, with more than six rotations. -
Page 22: Data Logger
Each time the data logger is stopped and started, the saved data log file is overwritten, since the PV78 does not support pause and resume logging. The APO function is disabled while the data logger is running, and the data logger will not start if the battery power is low. -
Page 23: Sharing A Data Log File With A Mobile Device
3. Open METERLiNK on your mobile device. The app will recognize the PV78 and begin showing real-time readings. Instructions for general use are provided in the application. 4. To share a file, long press the PV78 Transmit button . The transmit icon will flash on the PV78 display. -
Page 24: Changing The Data Log Time Stamp
Data Logger 9.4 Changing the Data Log Time Stamp The default time stamp is one minute, meaning that when the data log file is viewed on the mobile device, one reading will be shown for every minute of data logging. To change the time stamp, in order to view readings over a longer time inter- val, follow the steps below. -
Page 25: Maintenance
Maintenance 10.1 Battery Replacement To replace the 9 V battery, remove the screw located on the back (centre) of the meter and remove the battery compartment cover. When inserting a battery for the first time, remove the rectangular safety strip. Remove the old battery and dispose of responsibly and in accordance with all applicable regulations. -
