OPT101: Shall I measure 1MOhm resistance between pins 4 and 2 on bare device ?

Part Number: OPT101

Hi

Have few sensors, before soldring to the board, I guess if I'd measure the resistance between pins 4 and 2 by DVM I should see around 1MOhm of internal feedback

Am I wrong ?

I have several units at hand, one of them showing floating resistance of several hundred kOhm between pin 2 and 4, the other one shows nothing (like disconnection)

Is this normal ?

The units are bare, new, not soldered into PCB

Thanks

Alex
