Not sure best place to post.
Can someone please help me interpret the test results.
Had watch tested at Dakota Watch in USA using SM-8810. Asked for 100m test. Not sure they did it right.
Printout shows following:
Sampling Time 60 out of 60 seconds
Test Pressure: 0.268 BAR
Initial Strain: -001.7 um
Strain Trend: +000.0% um/min
Test 1: Passed
Sampling Time: 40 out of 40 seconds
Test Pressure: 5.156 BAR
Initial Strain: -092.0 um
Strain Trend: -001.5%um/min
Test 2: Passed
1. Was the max pressure tested only 50 meter (5 ATM) and not 100 meter as I asked for? 5 BAR = 5 ATM?
2. Can you explain the "initial strain". Is this the amount of movement detected in the crystal? Would a negative number mean the crystal was pushed into or out of the case? I imagine ANY movement of the crystal pushed out of the case is BAD = air entered the watch case?
3. Should I have the watch retested for 100 meter water resistance? Watch is rated at 200 meters.
