3.10 When warning lamp, o.r, or the Unit Indicator Flashes
113
This indication is displayed when the voltage or current exceeds 152% of the range. When using the voltage
1,000 V range, it is displayed when 1,060.5 V is exceeded.
For active power, [o.r] is not displayed until the 231.04% of the power range is exceeded, even if the voltage
or current reading is shown as [o.r]. The [o.r] indication is displayed for parameters calculated using [o.r]
data.
The [o.r] indicator is displayed under the following conditions:
3.10.3 When o.r (over-range) Is Displayed
Apparent power When [o.r] is displayed for either the voltage or current
Reactive power When [o.r] is displayed for the voltage, current, or active power
Power factor
• When [o.r] is displayed for apparent power
• When the apparent power is 0
Phase angle When [o.r] is displayed for the power factor
Frequency measurement When the reading falls outside the measurement range of 0.1 Hz to 100 kHz
Voltage waveform peak value When the reading exceeds 102% of the voltage peak range
Current waveform peak value When the reading exceeds 102% of the current peak range
Voltage crest factor
• When [o.r] is displayed for the voltage waveform peak value
• When [o.r] is displayed for the voltage, or the voltage is 0
Current crest factor
• When [o.r] is displayed for the current waveform peak value
• When [o.r] is displayed for the current, or the voltage is 0
Voltage ripple rate
• When [o.r] is displayed for the voltage waveform peak value
• When [o.r] is displayed for the DC voltage, or the DC voltage is 0
Current ripple rate
• When [o.r] is displayed for the current waveform peak value
• When [o.r] is displayed for the DC current, or the DC current is 0
Maximum current ratio
• When the power factor is 0
• When [o.r] is displayed for the current crest factor
Status Solution
When [o.r] is displayed for the
voltage
Switch to a range that does not result in an over-range condition. When [o.r] has been
displayed while using the 1,000 V range, stop measurement immediately, deactivate
power to measurement lines, and disconnect wires.
See: "3.2.3 Selecting the Voltage and Current Ranges" (p.43)
When [o.r] is displayed for the
current
Switch to a range that does not result in an over-range condition. When [o.r] has been
displayed while using the 20 A range, stop measurement immediately, deactivate pow-
er to measurement lines, and disconnect wires.
