"Power": press this key to power on, lift this key to power off

"Hold": Press this key to hold the data. Lift this key to the data sampling state. This key should be raised when measuring.

"UV365": Press this button when using the UV365 probe (the "UV420" button must be raised at this time)

"UV420": Press this button when using the UV420 probe (in this case the "UV365" button must be raised)

application

Industry is mainly used to monitor the blue-violet radiation, solar radiation monitoring, UV sterilization, graphic arts, UVEPROM erase, lithography exposure

The laboratory is mainly used for weathering research, UV disinfection, virology, microbial genetics, DNA research, and general laboratory applications

operating:

When performing UV irradiance measurement, first press the "Power" key, and then press the "UV365" (or "UV420") key and the selected range key according to the measurement needs to zero the data unit. After zeroing, insert the plug of the corresponding probe UV365 (or UV420) into the socket of the reading unit and place the photo-sensitive surface of the probe in the position to be measured. The product of the number and the range factor displayed on the display window is the irradiance value (unit: microwatt/cm 2 ) (Note: the “UV365” and “UV420” keys must not be pressed at the same time). If you want to keep the measurement data, press the "Hold" key (Note: You cannot press the "Hold" key before pressing the range key). After the reading is completed, the "HOLD" button should be lifted to restore the sampling state. After the measurement is completed, lift the power button (off).

note:

1. If only "1" is displayed at the left end of the display window, indicating that the irradiance is overloaded, the key should be measured by pressing a larger range factor; or

The "hold" button was incorrectly pressed before the range key was pressed, so it should be operated correctly.

2. "Power" "Hold" "UV365" "UV420" Four ranges are self-locking keys, and four range keys are interlocking keys.

3. When "LOBAT" or "←" appears at the upper left of the LCD panel, the internal battery should be replaced

Measurement considerations

If the measured value is less than 2000μW/c, please use "Lo" for higher accuracy

·The UV probe structure is precise. When not in use, please keep it in a dry environment. For example, put the whole probe in a plastic bag with desiccant and seal the bag mouth. This will prolong the probe life, otherwise it will reduce the probe acceptance sensitivity.
