3. Panel description
4. measurement procedure
1) press 'Power' to open the power
2) press 'Range' button, select the range
* If the display '----', out of range, select a similar high-range
3) zero steps
'199.9U W/cm2' Cheng She-
* The positive probe button to a table or other flat surface, bring it back up.
* Press the zero button, the display value is zero
4) the probe directly in UV light sources, UV values as shown on the LCD
5) data
* In the measurement process, press the 'Hold' key, read value will be locked, and'D.H' symbols for LCD displays
* Press the 'Hold' button again to cancel data hold function
6) data record (maximum/minimum read value)
* Read the data logging feature to show the minimum and maximum values. Click the 'Record' button, start data logging. 'REC' symbols for LCD displays
* When 'REC' symbol appears when
A) press the 'Recall' key, and maximum read value 'Max' a symbol will appear on the LCD
B), then press the 'Recall' key, 'Min' symbol and the minimum read value will be displayed on the LCD
C) press the 'Recall' key again, back to the data logging capabilities, symbol disappears
5. measurement considerations
* Structural constraints due to UV probe, probe output values after one year may be a deviation of about 1%, this is normal. Probe standard measuring cycle for one year.
* Due to the probe (filters) are very sensitive to climate change, preserve the environment is very important. Long time without this table, please make sure that the probe is stored in low humidity environments. For example, keep the probe in a dry plastic bag. Save the right way, the probe extend the life span of many
* According to the law of cosines, and 30 degrees of incident light, UV sensor input signal is well in line with the cosine law (in accordance with 95%). in the case of a 45-degree angle, and is in accordance with 90%. therefore, effective incident angle of 45 degrees, of course, it is limited to 30 degrees or less. calibration when the incidence angle is 0 degrees (vertical)
Save *UV probe
UV probe structure is extremely precise, when not in use, be sure to keep it in a dry environment. For example, the probe into a plastic bag with desiccant and seal.
Only when I have to take it out with the probe. With the above approach can prolong the life of the probe. Otherwise, the probe gain is reduced and correction cycles. In addition, regular replacement of desiccant.
6. other features
To prolong the life of the battery, this table has an automatic power off function, no operation for about 10 minutes, the unit will automatically shut down
To disable auto power off, press 'Record' in the measurement, select the memory record function
7. RS232 computer interface
RS232 ports via 3.5mm this table output connector output 16-bit data stream is available for users of special purpose
8. internal zeroing
4-3 zero zero steps is normal, however 'Zero' key adjustment range for only 20 units, if zero readings deviation exceeds 20 units, 'Zero' key no longer works, will display:
At this time we should be zero, follow these steps:
1) switch off the power supply
2) by pressing the 'Zero' button down and turn the power on until the LCD display as shown in the following figure, and then release the 'Zero' button
Top row shows: show zero readings
The following line shows: always show '0000'
3) VR9 read values back to zero
9. replacement of battery
1) when 'LBT' is displayed on the LCD, indicating battery output voltage is less than 6.5V-7.5V, batteries must be replaced, but can also be used after the low hours
2) open the battery cover, remove the old battery
3) fitted with a 9V battery (high power batteries), cover battery cover
