6.5 Current Measurement
Set the measuring mode to “Current Measurement” referring to 5.2.2 “Setting measuring
mode” when measuring a current.
(1) Connection
When the measuring power source of the meter is used, connect measuring
object such as a part and circuit between the “OUTPUT” terminal and “INPUT”
terminal on the panel of the meter as in measurement of insulation resistance.
The polarities of the “OUTPUT” terminal and “INPUT” terminal are “+” and “-”
(See 6.1.1 Functions of and Connecting Measuring Terminals) respectively.
Connect the terminals matching the polarities of the work. Be sue to use a
shielded-conductor cable as the measuring lead connected to the “INPUT”
terminal to prevent induced troubles such as noise and connect the shielded
conductor to the “GUARD” terminal.
Connect the “+” side of the work to the “INPUT” terminal and “-” side to the
“GUARD” terminal when connecting to a work that generates a current.
In this case also, be sure to use a shielded-conductor cable as the measuring
lead connected to the “INPUT” terminal and connect the shielded conductor to
the “INPUT” terminal.
