1)
Number of measuring CHs
1 (When using the single SME series)
NTB enables sequential measurement in a maximum 33 CHs
*MAX. 33 CH
(SME series 1 CH + 8 units of the NTB (32 CHs)
2)
Sampling period
(When using the single SME series.
Varies with the connecting NTB.)
Approx. 0.5 sec:
0 to ± 30000 um/m
Approx. 1 sec:
± 30000 to ± 300000 um/m
Measurement with civil engineering
transducer with temperature measuring
function
3)
Measuring function
RELATIVE measurement (relative value measurement):
Each value is obtained by deducting the ZERO value.
*ZERO value is equivalent to the initial unbalance value.
Capable of obtaining the ZERO value at arbitrary timing.
