Narrative:
I was the PF, we were doing the panoche 2 arrival into oak. I flew the descent to arrive at the runway in a 3:1 glide. I started down at the oak 97 DME, from FL310. We were given pilot's discretion to FL240, then FL200. The next controller gave us discretion to 16000 ft. About FL190 and 30 DME northwest of pxn, we were told to cross bored at 10000 ft. Bored is 48 northwest of pxn. It looked like we would not be able to make the restr, but I started a high rate of descent with spoilers to try and make it. My concern with making the crossing restr distraction me from calling for the 'in range' checklist. As a result, our altimeters stayed set to 29.92 inches. We told center that we would not be able to make bored at 10000 ft. He had us level at 14000 ft and do a 180 degree turn. During this turn we set the altimeters to the local pressure 30.17. We had been off altitude by 250 ft.

Title: LGT CARGO FLC FORGETS TO RESET ALTIMETER DURING DSCNT DUE TO FAILURE TO COMPLETE IN-RANGE CHKLIST.
Narrative: I WAS THE PF, WE WERE DOING THE PANOCHE 2 ARR INTO OAK. I FLEW THE DSCNT TO ARRIVE AT THE RWY IN A 3:1 GLIDE. I STARTED DOWN AT THE OAK 97 DME, FROM FL310. WE WERE GIVEN PLT'S DISCRETION TO FL240, THEN FL200. THE NEXT CTLR GAVE US DISCRETION TO 16000 FT. ABOUT FL190 AND 30 DME NW OF PXN, WE WERE TOLD TO CROSS BORED AT 10000 FT. BORED IS 48 NW OF PXN. IT LOOKED LIKE WE WOULD NOT BE ABLE TO MAKE THE RESTR, BUT I STARTED A HIGH RATE OF DSCNT WITH SPOILERS TO TRY AND MAKE IT. MY CONCERN WITH MAKING THE XING RESTR DISTR ME FROM CALLING FOR THE 'IN RANGE' CHKLIST. AS A RESULT, OUR ALTIMETERS STAYED SET TO 29.92 INCHES. WE TOLD CTR THAT WE WOULD NOT BE ABLE TO MAKE BORED AT 10000 FT. HE HAD US LEVEL AT 14000 FT AND DO A 180 DEG TURN. DURING THIS TURN WE SET THE ALTIMETERS TO THE LCL PRESSURE 30.17. WE HAD BEEN OFF ALT BY 250 FT.
