3.11 When PEAK OVER, o.r, or the Unit Indicator Flashes
115
This indication is displayed when the voltage or current exceeds 140% 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 196% 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:
3.11.2 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 either the voltage or current
• 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 220 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
Efficiency
• When [
o.r
] is displayed for the active power value used as the numerator or denom-
inator in the calculation
• When the active power value used as the denominator in the calculation is 0
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 voltage, or the voltage is 0
Current ripple rate
• When [
o.r
] is displayed for the current waveform peak value
• When [
o.r
] is displayed for the current, or the current is 0
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:
"3.2.4 Selecting the Voltage and Current Ranges" (p.48)
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 50 A range, stop measurement immediately, deactivate pow-
er to measurement lines, and disconnect wires.
