Results
The following modules can be used with the relevant settings for class B or A:
–
0.015% LT/m (0.05% LT/m) module – with a sensitivity of min. 0.12% LT/m (0.4% LT/m)
– 0.1% LT/m (0.25% LT/m) module – with a sensitivity of min. 0.2% LT/m (0.5% LT/m)
– 0.5% LT/m (0.8% LT/m) module – with setting 0.5% LT/m (0.8% LT/m)
