Two measuring methods: magnetic induction (F) and eddy current (N)
· ■ 2 measurement modes: continuous / single
· ■ 5 types of probes can be used (F400, F1, F10, N1, CN02,)；
· ■ 5 statistical ways: Mean values / Max. values / Min. values / testing numbers.(No.) / standard deviations (S.DeV)
· ■ 5 statistic values：mean value（MEAN）, max. value（MAX）, min. value（MIN）, numbers of measuring（NO．）, standard deviation（S．DEV）；
· ■ Direct testing mode and block statistics mode (APPL/BATCH)
· ■ Direct print out of statistical values
· ■ Low battery indication
· ■ 2 switch off modes: manual and auto
· ■ The instrument caters for the demands as follows:
GB/T 4956─1985 GB/T 4957─1985 JB/T 8393─1996
JJG 889─95 JJG 818─93
