WP 34S and 31S bugs and fixes

[Paul Dale]

Try two things:

• New batteries
• Set SLOW mode (from the MODE catalogue)
  

The symptoms you mention are likely related to low batteries. Ignore the reading from the BATT command, it is an instantaneous reading generally after a low power mode sleep. A continuing/long computation needs more power and lowers the available voltage. Also, purchase quality brand name batteries, rather than eBay cheapies.

For confirmation, try some of the inverse statistical distribution functions (i.e. the quantile functions). They are probably the most power intensive operations on the device. Inverse Gamma is a better on this front than these. The F distribution is probably the worst -- it should work fine with decent fresh batteries.
