Note :

This package does not include batteries.

Due to new rules of China Post Air, parcels must not include batteries,

otherwise it will not get through the custom.

> It is compact 3 1/2 digits digital multimeter for measuring DC and AC voltage,

DC and AC current, resistance, temperature, diode, transistor, continuity,


> It has polarity indication, data hold, MAX mode, overrange indication and auto

power off.

> It is easy to operate and is a ideal instrument tool.

Measuring AC/DC current >>>

Connect the negative(-) output lead of the selected clamp to the "COM " jack,

Connect the positive(+) output lead of the clamp to the "INPUT" jack.

Clamp the circuit to be measured with the clamp.

Read the reading on the display.
