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 A:1.0000 B:1.0000 C:1.0000
1P:1.0000
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.
observe the UPC meter display value
2.
use the following equation to calculate the new k factor:
test equipment value
new kFactor =old kFactor *
(
UPC meter display value
)
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.
