SECTION 8 CALIBRATION

8.3.1 K FACTORS DISPLAY

The correction factors (kFactors) created during EXTERNALLY REFERENCED CALIBRATION may
be displayed or modified directly, from the kFactors display screen. Activate the CALIBRATION
Menu (fn, 4), press 3 and the kFactor display appears as shown below.
Kin A:1.0000 B:1.0000 C:1.0000
Kex A:1.0000 B:1.0000 C:1.0000
Ki
Kin - are the kFactors for internal voltage sensing of phase A, B and C.
Kex - are the kFactors for external voltage sensing of phase A, B and C.
Ki - are the kFactors for current sensing of phase A, B and C.
1P - is the kFactor for single phase current sensing.
To manually calculate and enter a particular kFactor,
1.
2.
new kFactor = old kFactor *
You can simplify this calculation by first setting the k factor to 1.000. The new kFactor is then the ratio of
the external metered value to the UPC meter display value.
A:1.0000 B:1.0000 C:1.0000 1P:1.0000
observe the UPC meter display value
use the following equation to calculate the new k factor:
