Safety Symbols - Prokit's Industries Pro's Kit MT-1280D User Manual


For all DC measuring functions, to prevent the incorrect reading
resulting in potential electric shock, please use AC functions first to
check any presence of AC voltage, then switch to DC voltage
measuring range equivalent to or greater than the value of AC
voltage.

Before testing the resistance, diode, capacitor, or continuity function,
please make sure to cut off the power of the circuit and discharge all
the electricity.

Before measuring the current, please check the fuse first and make
sure to cut off the power of the circuit.

Before repairing the TV or measuring the power switching circuit,
please be careful of the possible impulse voltage to damage the
meter.

The meter is powered by 1 x 9V 6F22 battery that must be installed
into the battery case correctly.

When
immediately. The low level of a battery will result in incorrect reading
on the meter which leads to an unexpected incident.

According to measurement standards, the testing voltage shall not
exceed 1000V in category III and 600V voltage in category IV
respectively.

Do not use the meter if its case is not complete.
