OTHER PARAMETERS` DISPLAY MODE SELECTION :

 
         For selection to display the other parameters, press and hold the `UP`
and `DN`  keys  simultaneously  the  screen  will change in sequence PF, Ult 
and  AmP  release the keys when  desired  parameter  comes on screen. PF
is default  display,  any  power failure  will lead  to  display the power factor 
on priority basis. 
Voltage and Ampere are true RMS value, ct primary should be entered to
display the actual value. There is no effect of ct ratio on power factor.

CT Ratio :

  CT ratio is require to enter for accuracy of other  electrical 

parameters, there is no effect of CT ratio on power factor. 
Default factory setting is 100/5A. 

Step Delay : 

   Step delay is the time taken between two  continuous on

or off the steps. Setting Range - 1 to 20 (0.5 second to 10 seconds)
Default factory setting - 6 (2 seconds)
 

On Delay :

  On delay is the time between as H/L led becomes  green and

first step switched on. It is fold time of step delay.
                                        Setting Range - 1 to 20
                                        Default factory setting - 2
example : On delay = (step delay) x 2 = 4 seconds (factory default) 
 

Off Delay :

 off delay is the time between as H/L led becomes red

and first step switched off. It is also fold time of step delay.
                                        Setting Range - 1 to 20
                                        Default factory setting - 3
example : off delay = (step delay) x 3 = 6 seconds (factory default)
 

Sensitivity % of CT Current :

 This is the minimum set load 

in % (percentage), above this set value controller comes in normal 
working mode. (Below this lavel will display `L.ct` on screen.)
Setting Range - 1% to 20%,      default factory setting - 2%
