Scope and Multimeter Operations
Getting Started
NOTE:
i
200V to 400V scales are not to be used to measure signals greater than 50VAC (rms) or 75VDC.
IMPORTANT:
Do not use the Low Amp Probe to measure current on conductors at a potential greater than
46VAC peak or 70VDC.
8.3.2 Leads, Probes and Adapters
The Scope Module uses standard safety banana plugs that are compatible with many
accessories. The various leads, probes, clips, and adapters that are supplied with, or available as
optional equipment, are explained in this section.
IMPORTANT:
When removing leads from their sockets, do not pull on the wire because it can damage the leads.
Pull on the plug.
