For example:
SCREEN #5: “Hold To Reset”.After the baseline is reset
by holding down the “MODE” key for more than 3 seconds,
the screen will display “done”.
When the screen changes to “done", indicating that the baseline was reset
SCREEN #2 (percentage) will show 100 (%) and SCREEN #4 (days) will show
0 (days).
Tapping the “MODE” key once more will advance the unit to SCREEN #6.
SCREEN #6 will scroll either “beeper enabled” or “beeper disabled” depending on
the last saved state of the alarm buzzer. To change between states, hold down
the “MODE” button while in this screen for more than 3 seconds.
Screen 6
“Beeper enabled”:
When the beeper is enabled the radiometer will beep when the “MODE” key is
pressed and also when the measured lamp percentage is lower than YYY%,
where “YYY%” equals a factory programmed threshold.
“Beeper disabled”:
When the beeper is disabled the unit will not beep during alarms, but will continue
to beep on key presses.
For example:
The state of the beeper (enabled/disabled) is saved in non-volatile memory and
will not be affected by a loss of power.
SCREEN #6: “beeper enabled” or “beeper disabled”

The following scrolling screens will indicate abnormal operations of the radiometer.
The radiometer will revert to normal operation once the problem is corrected:
1- “Connect Sensor” – a proper sensor is not attached to the radiometer.
To correct this error check that the sensor is properly plugged into the unit.
2- “Sensor Saturated” – the sensor detects UV intensity greater than 21,300

µW/cm . To correct this error move the sensor to a more suitable distance from
the UV source being measured.
Error Screens
Factory Programmable Thresholds
Thresholds are expressed by measured lamp percentage.
aa%: Green LED threshold
bb%: Yellow LED threshold
cc%: Blinking RED LED threshold
YYY%: Buzzer threshold
LED color indication:
Green: > aa% of the UV irradiance
Yellow: aa - 1% to bb% of the UV irradiance
Red: < bb% of the UV irradiance
Blinking RED : < cc%
Defaul thresholds:
LED color indication:
Green: 75% - 100% UV Intensity
Yellow: 60% - 74% UV Intensity
Red: 40% - 59% UV Intensity
Alarm: 0% - 39% UV Intensity
