VII Notes
1. Do not touch the metal parts of the test line during measurement process to avoid electrical
injury.
2. Measurement wiring must operate in strict accordance with the instructions to ensure personal
safety.
3. Better use of power outlet with ground.
4. Do not work in the case of excess voltage and current limits.
5. Each clamp must be accordance with the corresponding socket on the panel, otherwise it will
affect the test results.
6. You must follow the principles of accessing the instrument before the device under test when
connecting to the instrument, and the principles of removing the device under test before the
instrument when splitting the instrument for voltage line and clamp.
7. Pay attention that you must turn off the power supply switch whenever testing is finished,
because sometimes the LCD backlight automatically goes into power-saving mode, but the LCD
screen does not display while the instrument is still working as normal. That’s why you must turn
off the power switch.
8. When monitoring during a long time, be sure to connect to the power wire, otherwise the
internal power supply will be so exhausted that it’ll be unable to complete the monitoring.
