Panel Description 4. Measurement procedure 1) Press "Power" button to turn on the power 2) Press the "Range" button, select the maximum range * If "----", indicating out of range, select high close range. 3) the range is set to zero step "199uW / cm2" * Flip the front of the probe to a desk or other flat surface, so that the back up. * Press the zero button, the display value is zero. 4) The UV light probe placed directly under, LCD is shown on the UV values. 5) Data Hold * During the measurement, click the "Hold" key, the reading will be locked, while the LCD display "DH" symbol * then click the "Hold" button, cancel the data hold function. 6) Data Record (Max / Min reading) * Data logging function displays the maximum / minimum readings. Click "Record" button to start recording data. LCD display "REC" symbol. * When the "REC" symbol displayed a) Press the "Recall" key, "Max" symbol and the maximum reading will be displayed on the LCD. b) then click the "Recall" key, "Min" symbol and minimum readings will be displayed on the LCD. c) then click the "Recall" key to return to the data recording function, related symbol disappears. 5. Measurement Considerations * UV probe due to structural limitations, the output value of the probe may be about 1% of the variation in the year, this is normal. That probe calibration cycle of one year. * As the probe (filter) is very sensitive to changes in humidity, so save the environment it is very important. When long time without this form, make sure the probe stored in low humidity environments. For example, the probe stored in a dry plastic bag. Preservation methods properly, the probe will extend the life of many. * Depending on the law of cosines, incident at 30 degrees, the input signal UV probe> 95%. In the case of a 45-degree angle, then> 90%. Therefore, effective angle of incidence of 45 degrees, of course, is preferably limited to less than 30 degrees. Calibration when the incidence angle should be 0 degrees (vertical). 6. Cancellation / automatic shutdown to extend battery life, the watch has an automatic shutdown, no operation for about 10 minutes, the machine will automatically shut down to disable automatic shutdown in the measurement press "Record", select the memory record. 7. Internal zero in 4-3 years of zero is zero normal step, but the adjustment range "Zero" key of only 20 digits, if the reading is zero deviation exceeds 20 internal units of words, "Zero" button on no longer work, and will show: this time will be for internal zeroing, the steps are as follows: 1) Turn off the power 2) Press the "Zero" key, turn on the power until the LCD display as shown below, then loose open "Zero" key. Uplink: Displays internal zero readings downlink show: Always show "0000" 3) adjusting the VR3, so that reading the display back to zero. 8. Replace the battery 1) When the LCD displays "LBT", the battery must be replaced, but showed low power can continue to use a few hours 2) Open the battery cover, remove the old battery. 3) mounted on a 9V battery (006P, PP3 type), battery cover.
