You can have one or two problems (depending on the version numers you're using)
1) You are using not an comformance (read correct filtered) sample
2) You're comparing different Pesq algo's to each other

sorry im not cleared
when i compared with nemo outdoor 5 ..it happened again but.the value between NO5 and NH2.9 not much as comparing NO4 and NH2.9, more decrease using NO5. im using the same scenario and lock the same band and channel but i still dont get it..why the nemo handy value more unstable ?
in your opininion sir DCA which the valid one for MOS measurement NO or NH ?
thanks

Use the ITU PESQ ref samples to get the answer straight.
Later versions of Nemo are using the P-S-Y-T-E-C-H-N-I-C-S dll and it causes trouble. Earlier versions using the O-P-T-I-C-O-M dll which is more stable. But it all depends on using the correct reference sample.
Can't tell if NO or NH is better, don't use NH myself
