Select the standard (LS-STD, JJG 879-2015)

• Short press the “ ” or “ ” button to select the standard.
• LS-STD: Calibration in accordance with enterprise standards.
• JJG 879-2015: Calibration in accordance with China national standard.
• Short press the “ ” button to enter the measurement mode.

Measurement mode

• In the measurement mode. The system displays the real-time value, maximum value, minimum value, average value, measurement duration, energy value (Energy display =Yes)

• In the measurement mode, if the backlight is off, press the “ ” button to light the backlight; if the backlight is already lit, short press the “ ” button, and the “HOLD” icon will be displayed in the lower left corner of the interface. All data will be kept on the LCD, and the current data will be saved to the history record.
• In the “HOLD” state, if the backlight is off, press the “ ” button to light the backlight; if the backlight is already lit, short press the “ ” button to cancel the HOLD function and start a new measurement.
• In the measurement mode, if the backlight is off, short press the “ ” button to light the backlight; if the backlight is already lit, press the “ ” button to clear up the current data and start a new measurement.
• In the measurement mode, short press “ ” or “ ” to enter the record data query mode.

Record data query mode

• No.1 is the latest record data (up to 9 records are stored in the instrument, and the oldest record will be deleted automatically when exceed 9 records).
• Short press “ ” or “ ” to scroll up or down a record.
• Long press the “ ” button 3 second to clear all records.
• Short press the “ ” button to enter the measurement mode.

Precautions

1. When not in use, please long press the “ ” button to power off the instrument.
2. Avoid contacting with corrosive materials and keep away from high humidity.
3. After shutdown, store it in a special packing box and keep it in a safe place. Protect the photosensitive part of the probe from polluting.
4. The recommended period of calibration is one year.
5. Because the UV probe is sensitive to humidity, the environment in which it is stored is important. When not in use for a long time, be sure to store the instrument in a low humidity environment.
6. When the instrument displays low battery, replace the battery.
