Average current: (5.5+5.2+4.0) / 3 = 4.9 amps
L1 current unbalance: (5.5 - 4.9) / 4.9 = 0.1224
L2 current unbalance: (5.2 - 4.9) / 4.9 = 0.0612
L3 current unbalance: (4.0 - 4.9) / 4.9 = -0.1837
Maximum current unbalance:
Maximum (|0.1224|, |0.0612|, |-0.1837|) = 0.1837
Current unbalance converted to a percentage:
100 * (0.1837) = 18%
Altitude Correction Factors
If a Raritan differential air pressure sensor is attached to your device, the
altitude you enter for the device can serve as an altitude correction factor.
That is, the reading of the differential air pressure sensor will be
multiplied by the correction factor to get a correct reading.
This table shows the relationship between different altitudes and
correction factors.
Altitude (meters)
Altitude (feet)
Correction factor
0 0 0.95
250 820 0.98
425 1394 1.00
500 1640 1.01
740 2428 1.04
1500 4921 1.15
2250 7382 1.26
3000 9842 1.38
