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

transformer jaw of the Meter.

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
