2.6 Activating Power to the Measurement Lines
36
Before activating power to the measurement lines
Once measurement is complete, turn the POWER switch off ( ).
Disconnect the wires.
When power is turned on again, the instrument will start up with the settings that were in effect when it was
turned off.
2.6 Activating Power to the Measurement Lines
Before activating power to the measurement lines, turn on the instrument and verify that no
errors are displayed.
If any measurement target lines are live before the instrument is turned on, the instrument
may be damaged, or an error may be displayed when it is turned on.
See: "2.4 Turning On the Instrument"(p.34), "6.2 Error Indication"(p.166)
The instrument and input terminals may become hot when a large voltage or current is input.
2.7 Turning Off the Instrument
When the instrument is turned off, do not apply voltage or current to the instrument. Doing so
may cause the instrument to become hot, resulting in burns or damage to the instrument.
• When the instrument is turned off, the input resistance of the current input terminals will be approximately
500 m.
• If leaving the connections in place after measurement is complete, be sure to conduct a pre-measurement
inspection (p.37) before making the next measurement. Such an inspection will enable you to prevent
electric shock and measurement errors caused by breaks in cables, short-circuits, instrument failures, and
other issues.
