and UVALED-X3, the meter enter the next setting item. If not, the meter enter the measurement
mode.
E. Standard Selection
Short press the “ ” button or “ ” button to select the standard.
LS-STD (Enterprise standard): The meter is calibrated according to Linshang standard.
JJG 879-2015 (Chinese standard): The meter is calibrated according to Chinese standard.
Short press the “ ” button to confirm the setting and the meter enters the measurement mode.
3. 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, short press the “ ” button to light the backlight; if the
backlight is already lit, short press the “ ” button to cancel the HOLD state 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.
