4. Operational guidelines
4.1 Reading hold
During the process of measurement, gently touch the key if you want to hold readings, and
monitor's display value will be locked. Touch again the key , the readings hold will be removed.
4.2 Backlight
1）In the process of measurement, if the measurement environment is too dark, press the key
for more than 2 seconds to enable backlight function. Then about 1 minute later, the backlight
function will be automatically disabled.
2）During this process, press the key for 2 seconds to disable backlight.
4.3 Auto shutdown
1）If no operations occur within 10 minutes after the initialization, the instrument will be in the state
of dormancy. Auto shutdown at this moment can save power consumption. 2 minutes before
shutdown, the buzzer will sound at an interval of 1 minute.
2）Press any key after Auto shutdown to wake the instrument into operation.
3）The function of Auto shutdown will be disabled if SEL/NCV key is pressed while the instrument is
initialized.
4.4 AC current measurement
1）Turn the rotary switch to switch to the AC measuring range, hold the trigger, open clamp head,
put a lead wire of the line to be measured into the clamp. Then the primary display panel will display
the measured current value while the secondary display panel will show the measured frequency
value.

4.5 DC voltage measurement
Turn the selector switch to AC/DC voltage position, press SEL key to switch to DC voltage
measurement mode, and connect the pen-shaped meter to the signal to be measured. The red
meter is connected to the positive pole of the signal to be measured and the black meter to its
negative pole.
4.6 AC voltage measurement
1) Turn the selector switch to AC/DC voltage position and press SEL key to switch to AC voltage
measurement mode, connect the pen-shaped meter to the signal to be measured. Then the
primary display panel shows the measured voltage value and the secondary display panel the
measured frequency value of voltage.
