User Maintenance
• Always use clean confining fluid. Contaminants can increase the fluid's electrical conductivity. This will
affect the readings from the in-vessel instrumentation.
• When the confining fluid needs changing, use only MTS approved oil. We recommend Multitherm ®
PG-1, a highly refined, clear, and non-toxic mineral oil.
• Always clean oil, debris, and water from the baseplate, platen, feedthroughs, cap screw holes, and
high pressure seal after each test. Debris can scratch the high pressure seal, resulting in nuisance
leaks.
• Replace the eight sealing cap screws after every 1000 pressure cycles (approximately every five years).
Use only MTS approved cap screws.
• Before each test, check the bell and platen assembly for cracks.
