You should raise it to 443 minus, (a little less than 443)as it will pull back down to 442. If you use a 440 fork then 442 will be two beats per second higher. Also if you tune when the temperature of the performace will be higher, that will also tend to lower the pitch. But it all depends on the piano and what the deviation will be. Ask the ensemble what they use as a pitch reference. If it is electronic, you can demonstrate how the tuning fork used as a pitch reference is affected by temperature. Compare your fork to their meter. Now hold the fork in you hand for 30 seconds then compare it to the meter. Probably the meter will show the fork is slightly flat. It is wise to set the pitch to the performer's pitch reference. If you ask them for this they will appreciate your efforts even more.
