Maintenance
• Batte ry Replac ement
Before attempting open the battery cover of the meter, be sure that
test leads have been disconnected from measurement circuit to
avoid electric shock hazard.
Warning
- Loos en th e screw f ixi ng the ba tte ry cove r and r emove i t.
- Repl ace t he exha ust ed batt ery w ith a new o ne.
- Put th e bat te ry co ver a s its ori gin .
• Fuse Re placeme nt
- Loos en th e screw f ixi ng the ba tte ry cove r and r emove i t.
- Repl ace t he blow n fus e with ra tin gs spec ifi ed.
- Put th e bat te ry co ver a s its ori gin .
Before attempting open the battery cover of the meter, be sure
that test leads have been disconnected from measurement
circuit to avoid electric shock hazard.
For protection against fire, replace fuses only with specified
ratings: F 200mA/250V (quick acting).
Warning
• Test Le ads Repla cement
Full in compliance with safety standards can be guaranteed
only if used with test leads supplied. If necessary, they must
be replaced with the same model or same electric ratings.
Electric ratings of the test leads: 1000V 10A.
