requires The same cauYilins as thTMOVATS 70'OTSYSTEM.
The 2100 SYSTEM does not require a scope zeroing process but may require a load span adjustment. On the MOVATS penthouse, set the load cell button in or out depending on which load cell is used (50k or 200k).
The MOVATS 2150 SYSTEM has the same basic control switches'and requires the same cautions as the MOVATS 2000 and 2100 SYSTEMS.
The MOVATS 2150 SYSTEM has the capability to interchange TMDs with another 2150 SYSTEM.
The Load cell (50k or 20 k) may be interchanged between the 2000 SYSTEM, 2100 SYSTEM , and 2150 SYSTEM; however, mating a load cell with one system will reduce the amount of-load cell span adj us tments .
The MOVATS 2150 SYSTEM has an additional piece of equipment ,
Torque Switch Transducer, for measuring s7 ring pack displacement.
This Torque Switch Transducer is only'to'ae used with the MOVATS
( 2150 SYSTEM.
