2.2 ENTERING THE DATA ANALYSIS MODE:
Before entering the Data Analysis mode, take a current reading, then shut down the Meter by pressing the “ON/OFF Mode”button two times rapidly.
Then, to enter Data Analysis mode, press the “ON/OFF Mode”button two times rapidly. This will turn the unit back on and put you in Data
Analysis mode where you can compare the baseline measurement to the current measurement you have just taken. By pressing the “On/Off/Mode”
button once, you can toggle through three screens described in Section 2.3.
2.3 FEATURES AND OPTIONS IN DATA ANALYSIS MODE:
The base line profile can be identified by the letter "B" in the lower left corner of the display as shown below. The total exposure time and the
maximum irradiance are displayed. They are 26 seconds and 271 mW/cm
2
respectively.
The current profile is from the most recent measurement. The current profile is identified by the letter "C" in the lower left corner of the display as
shown below. It is easy to see in this example that the maximum irradiance of the system has not changed, as the maximum irradiance values of the
base line above and current profiles are the same (271 mW/cm²).
The difference screen below shows the percentage difference in the irradiance profiles between the baseline and the current profile. The "7D" in the
lower right corner shows that there were 7 days between the time the baseline and current measurements were taken. It also shows that the middle
peak irradiance was 32% lower than the baseline.
3.0 BATTERY CHARGING
The Meter contains Nickel Metal Hydride Rechargeable Batteries and comes with a trickle charger.
Plug the charger into an AC outlet, then connect the cable to the meter. A red and green LED will light on the lower left corner of the meter to
indicate the cable is properly inserted into the meter and the meter is charging. The meter will fully charge after approximate 3 to 5 hours of
continuous charging. The red and green LED will turn only green when the meter is fully charged. The LED will not light unless the charger is
plugged into power and the meter. Henkel recommends keeping the meter and the charger plugged in and charging when not in use.
4.0 MAINTENANCE
The Meter is a very rugged instrument and should not require any maintenance other than cleaning.
Note: It is important to keep the shiny surface
clean and to avoid contaminating the input optic.
It is recommend using lens cleaner and a soft cloth to prevent scratching the housing. Over time
the band pass filters and integrating sphere in the Meter may begin to degrade due to the extreme UV exposure. This gradual degradation manifests
itself in changes in total transmission and band pass characteristics, both of which adversely affect the calibration. It is, in part, for this reason that the
Meter should be recalibrated on an annual basis. In some cases, with extreme use (irradiance, frequency, or temperature) shorter calibration cycles
are required.
5.0 RECALIBRATION:
Calibration is recommended once a year. The recalibration procedure includes evaluation of the charging system and batteries, evaluation of the
internal optics (sensor, filter and integrating sphere), and a complete optical and electrical calibration traceable to N.I.S.T. For calibration and repair
services contact Henkel Equipment Services.
