LMP91000: Sensor Test Procedure

Part Number:LMP91000

Dear Community,

I am using LMP91000 for CO detector design. My application needs sensor test procedure. According to 8.2.2.1 of datasheet, when i modify REFCN register(bias settings) , Vout signal should change respect bias. When i return the initial settings, Vout signal has returned its previous state. 

I made test procedure according to 8.2.2.1 of datasheet. But, Vout signal changes twice respect one test procedure. What might be the reason for this ? 

On the other hand, i examine LMP91002 datasheet, I saw that the test procedure changed. In LMP91000, test procedure has two pulse, in LMP91002 test procedure has one pulse.

Is there a reason for this change ?   

Do you propose LMP91002 procedure for LMP91000 ?    

Thank you.
