Clamp Multimeter METRACLIP 86
English
Note (2) - Any applied voltage greater than 1000V causes the emission of an
intermittent alarm beep to report a dangerous overload.
Note (3) - The measurement result may be perturbed by an instability linked to the
current measurement (approximately 0.1A).
Example: for a power measurement made at 10A, the instability of the
measurement will be 0.1A/10A or 1%.

Note (1) - Display of O.L
- Above 600kW in single-phase (1000V x 600A).
- Bandwidth in AC in voltage = 3 kHz, in current = 3 kHz
Notes (2) and (3) of the previous § apply.
Note (4) - Any power measured less than 5W is regarded as zero and causes the
display of dashes "----"
- If the voltage is less than 0.15V or if the current is less than 0.15A, the
power measured is regarded as zero and causes the display of dashes "----"
Note 5 - The active powers are positive for power consumed and negative for
power generated.
Note 6 - The signs of the active and reactive powers and power factor are defined
by the four-quadrant rule below:
- The diagram below sums up the signs of the power as a function of the
phase angle between U and I:
Quadrant 1 : Active power P
sign + (power consumed)
Quadrant 2 : Active power P
sign - (power generated)
Quadrant 3 : Active power P
sign - (power generated)
Quadrant 4 : Active power P
sign + (power consumed)
