Model UT202A is 2000-count stable, safe and

reliable digital clamp multimeter(hereafter

referred to as "the Meter"). It is designed with

large-scale integrated circuits and A/D

converter as the core as well as the overload

protection and novel structure, which make

it a superb tool for electricians.

otherwise it will casue deviation. The Meter

can only measure one conductor at a time,

to meausre more than one condutor at a

time will cause deviation.

Note:

When current measurement has been

completed,disconnect the connection between

the conductor under test and the jaw, and

remove the conductor away from the

A. General Service

● Periodically wipe the case with a damp cloth

and mild detergent. Do not use abrasives or

solvents.

● To clean the terminals with cotton bar with

detergent, as dirt or moisture in the

terminals can affect readings.

● Turn the Meter power off when it is not in

use.

● Take out the battery when it is not using for

a long time.

● Do not use or store the Meter in a place

of humidity, high temperature, explosive,

inﬂammable and strong magnetic ﬁeld.

To measure current, do the following:

1. Set the rotary switch to 20A ,200 A or

600 A .

2. Press the trigger to open the t nsfo er jaws.ra rm

3. Center the conductor within the transformer
