2. With a high-speed sampling speed of 2048 times per second, accurately calculate the UV energy

value.

3. Have statistical function, directly display real-time value, maximum value, minimum value, average

value and measurement duration.

4. Suitable for measuring the intensity and energy of UV LED light source for UV curing machine..

V. Operations

1. Power on/off

 Power on: Press “ ” to power on the instrument. After powering on, the instrument displays the

calibration coefficient, calibration date, production date, version number, serial number and other

information. Then enters the measurement mode.

 Power off: Long press the “ ” button to power off; or the instrument will automatically power off in

10mins after no operation when Auto Off set ON.

In the setting mode, “ ” and “ ” are Select buttons, and “ ” is the Confirm button.

A. Select whether to automatically power off (Auto Off: ON/OFF)

Short press the “ ” or “ ” button to select ON/OFF

Selecting ON indicates that the instrument automatically powers off in 10mins after no operation.

Selecting OFF indicates that the user has to manually turn the instrument off, and the instrument will

not automatically power off.

Short press “ ” button to complete the setting and enter the next Set option.

B. Whether to display the energy value (Energy display: ON/OFF)

Short press the “ ” or “ ” button to select ON/OFF

Short press “ ” button to complete the setting and enter the next Set option.

C. Smooth (OFF/50HZ/60HZ)

If UV light source powered by AC power supply, the AC frequency affects the power measurement,

so that the smoothing process becomes necessary for those probes with high sampling speed (2048

times/second), enter the smooth setting mode, short press the “ ” or “ ” button to select.

OFF: Select this option, if UV light is DC powered and does not need smoothing

50HZ: Select this option for 50HZ AC

60HZ: Select this option for 60HZ AC

Short press “ ” button to complete the setting and enter the next Set option.
