For continued protection , replace the line fuse(s) only with fuse(s) of the same voltage and current rating
and type. DO NOT use repaired fuses or short-circuited fuse holders.
Keep away from live circuits: Operating personnel must not remove equipment covers or shields.
Procedures involving the removal of covers or shields are for the use of service-trained personnel only.
Under certain conditions, dangerous voltage may exist even with the equipment switched off. To avoid
dangerous electrical shock, DO NOT perform procedures involving cover or shield removal unless you are
qualified to do so.

Measuring high voltage is always hazardous: ALL multimeters input terminals (both front and rear) must
be considered hazardous whenever inputs greater than 42V (dc or peak) are connected to ANY input
terminal.
Permanent wiring of hazardous voltage or sources capable of delivering greater than 150VA should be
labeled, fused, or in some other way protected against accidental bridging or equipment failure.
DO NOT leave measurement terminals energized when not in use.
