PM3255 Digital Output - External Mode

Anonymous user · ‎2016-09-08

I'm struggling to work out how to enable the External mode for the digital output for the PM3255. Is this dependent on the firmware or possibly some other setting? I've been through the configuration on the meter itself and only get 3 options for both DO1 and DO2. Any ideas out there?

Hi Paul,

You can change the DO mode to External from the meter front panel. Go to Setup->DO->Mode.

However be aware that DO can be set to external mode only if you have fw 1.0.500 and greater.

Hi Paul,

PM3255 firmware field upgrade feature will be available, only for the meters which will be manufactured from March 2017.
