1. The section is very important for safety. Read and understand the

following instruction fully and maintain your instrument properly.

2. aTheinstrumentmustbecalibratedandinspectedatleastonce

year to maintain the safety and accuracy.

WARNING

6-1 Maintenance and inspection

1) Appearance

●Is the appearance not damaged by falling?

2) Test leads

●Is the cord of the test leads not damaged?

●Is the core wire not exposed at any place of the test leads?

Note：

If the built-in fuse is blown, only the current measurement becomes impossible.

Note：

Make sure that the test leads are not cut, referring to the section 5-1.

more information, please contact the dealers.

6-3Battery and Fuse Replacement

1. If the rear case or the battery lid is removed with input applied to

theinputterminals,youmaygetelectricalshock.Beforestartin g

the work, always make sure that no input is applied.

2. Before starting the work, be sure to turn OFF the main unit power

and release the test leads from the circuit.

3. Be sure to use a fuse of the specified rating or type. Never use a

substitute of the fuse or never make a short circuit of the fuse.
