WARNING

7HVW/HDGVDQG/HDGFDEOHV

• Use the products provided by YOKOGAWA for this device.

• Do not use degraded or damaged test leads or lead cables.

Check the continuity of the test leads and lead cables.

• When you attach or remove the test leads or lead cables or remove the case

(for example to change the batteries), be sure to remove the lead cables

from the circuit under measurement.

• When you remove the case (for example to change the batteries),

be sure to remove the test leads and lead cables from the instrument.

• There are caps at the ends of the test leads.

To ensure safety (safety standard EN 61010-031), be sure to put the caps on

the leads when you use them.

'DPDJHG6LJQDO&DEOH

If the signal cable (test leads and lead cables) is torn and the inner metal is

exposed or if a color different from the outer sheath appears, stop using

the cable immediately.
