These lamps will light up if the voltage input or current input waveform peak value exceeds the figures listed
below. At this time, the displayed data is not accurate.
• Voltage input waveform peak value: ±600% of the voltage range
When using the 300 V, 600 V, or 1,000 V range, ±1,500 Vpeak
• Current input waveform peak value: ±600% of the current range
When using the 20 A or 50 A range, ±100 Apeak
3.11 When PEAK OVER, o.r, or the Unit Indicator
Flashes
3.11.1 If the PEAK OVER U or PEAK OVER I Lamp
Lights Up
Error display Status Solution
PEAK OVER U When greater than or equal
to ±1,500 Vpeak Stop measurement immediately, deactivate power to measurement
lines, and disconnect wires.
When less than ±1,500
Vpeak The internal circuit is not operating properly. Switch to a range for
which the
PEAK OVER U lamp does not light up.
See: "3.2.4 Selecting the Voltage and Current Ranges" (p.48)
PEAK OVER I When greater than or equal
to ±100 Apeak Stop measurement immediately, deactivate power to measurement
lines, and disconnect wires.
When less than ±100 Apeak The internal circuit is not operating properly. Switch to a range for
which the
PEAK OVER I lamp does not light up.
