3.10 When warning lamp, o.r, or the Unit Indicator Flashes
112
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 V peak
• Current input waveform peak value: ±600% of the current range
When using the 20 A range, ±60 A peak

3.10.1If the PEAK OVER U or PEAK OVER I Lamp
Lights Up
Error display Status Solution
PEAK OVER U
When greater than ±1,500 V
peak
Stop measurement immediately, deactivate power to measurement
lines, and disconnect wires.
When less than ±1,500 V
peak
The internal circuit is not operating properly. Switch to a range for
which the PEAK OVER U lamp does not light up.
See: "3.2.3 Selecting the Voltage and Current Ranges" (p.43)
PEAK OVER I
When greater than ±60 A
peak
Stop measurement immediately, deactivate power to measurement
lines, and disconnect wires.
When less than ±60 A peak The internal circuit is not operating properly. Switch to a range for
which the PEAK OVER I lamp does not light up.
See: "3.2.3 Selecting the Voltage and Current Ranges" (p.43)
3.10.2 If the CURRENT ● Lamp Flashes
Status Operation Solution
Forcibly changes the range to the 200
mA range if current of greater than or
equal to ±612 mA peak is inputted con-
tinuously for 10 or more seconds when
using a range from 1 mA to 100 mA with
fixed range, and the CURRENT
● lamp
will flash.
* If the 200 mA range has been disabled
using the range select function, the
range will be switched to an enabled
range greater than the 200 mA range.
Integration will be
forcibly stopped
(causing the RUN
lamp to flash), and it
will not be possible
to resume integra-
tion operation.
Instrument protection mode can be canceled by perform-
ing any of the following actions, causing the CURRENT
●
lamp to turn off:
• Pressing one of the current range keys
• If integration has stopped, resetting integrated values
• If integration has been reset, pressing key
• Performing a system reset
• Performing zero-adjustment (Available only in the inte-
gration reset state)
• Turning the instrument off, and then on again (inte-
grated values will be reset)
