Hioki PW3336-01 - When PEAK OVER, O.r, or the Unit Indicator Flashes; 1 If the PEAK over U or PEAK over I Lamp Lights up

3.11 When PEAK OVER, o.r, or the Unit Indicator Flashes
114
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

Flashes
3.11.1If 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.
