SECTION 8 

CALIBRATION 

 

103 

8.3.1  K FACTOR 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. 

It is recommended that the kFactors are reset to 1.000 before calibration.  The new kFactor is then the ratio 
of the external metered value to the UPC meter display value.  This minimizes error and will provide the best 
results. 

 

new kFactor  = 

 ( 

test equipment value 

) 

UPC meter display value 

 

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: 

 

new kFactor  = old kFactor * 

( 

test equipment value 

) 

UPC meter display value 

 

8.3.2  RESET ALL KFACTORS

 

Reset all kFactors to the factory default value (1.000). 

Activate the CALIBRATION Menu (

fn,

 

4

), press 

1

 and the kFactor reset warning appears as shown 

below. 

 

 

 WARNING: RECALIBRATION REQUIRED 

 PRESS "EXECUTE" TO CONTINUE 

 PRESS "CLEAR" TO CANCEL 

  

 

 

NOTE:  The UPC and Power Source will continue to operate properly but accuracy will be only about 
2%.  You will have to recalibrate your power source for accurate output and metering.
