1.5 Safety Information
Warning! Please read through the following safety information before
using the product.
To avoid possible electric shock or personal injury, please read and follow
these guidelines carefully:

Follow the guidelines in this manual and DO NOT use the Meter if the case
is damaged. Check the Meter case and terminals, and make sure all the
devices are in the proper positions.

Do not apply excessive voltage to the Multimeter. Apply voltage within
the rated range only.

Use caution when measuring voltages above 30 V RMS, 42 V peak, or 60
V DC. These voltages pose an electric shock hazard.

When using the probes, always keep your fingers behind the finger
guards.

Always connect the common test leads (black) before connecting the live
test leads (red), and disconnect the live test leads (red) before
disconnecting the common test leads (black). This will reduce the chance
of an electric shock.
