77. A scale factor is the multiplier expressed as a power of 10 For example a multiplier of 10 is represented as a scale factor of 1 since 10 10 a multiplier of 100 is repre sented as a scale factor of 2 since 107 100 If the circuit monitor displays OFLO for any reading the scale factor may need to be changed to bring the reading back into range For example since a circuit monitor register cannot store a number as large as 138 000 a 138 kV system requires a multiplier of 10 138 000 is converted to 13 800 x 10 The circuit monitor stores this value as 13 800 with a scale factor of 1 since 10 10 The circuit monitor front panel would display the value as 138 00 with the KILO units LED lit Scale factors are arranged in scale groups The abbreviated register list in Appendix B shows the scale group associated with each metered value The command interface can be used to change scale factors on a group of metered values The procedure on the following page tells how Notes e It is strongly recommended that the default scale factors which are automati cally selected by POWERLOGIC hardware and software not be changed e When using custom software to read circuit monitor data over the communi cations link you must account for these scale factors To correctly read any metered value with a scale factor other than 0 multiply the register value read by the appropriate power of 10 e When you change a scale factor all min max v
