BESANTEK 1. Safety Rules & CAUTION RISK OF ELECTRIC SHOCK This tester has been designed with your safety in mind. However, no design can completely protect against incorrect use. Electrical circuits can be dangerous and/or lethal when lack of caution or poor safety practices are used. -
Page 4: Safety Check
BESANTEK Avoid bare hand to hand contact between the tester and extended test leads. When using the tester with test leads, ensure that they are safe and properly authorized. Disconnect the tester from any external circuit when checking or changing the Fuses. - Page 5 BESANTEK When replacing the fuse use only the type specified, HBC fuse, and insert correctly into the fuse holder. Always double check the lead connections before making measurements. This instruments has 2 internal fuses. For increased safety, use fused test leads (optional).
