short circuit screw 1H turned in

Probe Test Results (Stated 90o pulse lengths are the best achieved during installation. To reduce risk of damage to the probes, facility users should use slightly lower RF nutation frequencies (i.e. longer 90o pulse lengths) where possible. Please discuss with the facility manager appropriate RF nutation frequencies for your experiments.)

Nucleus 90o Pulse (us) Power (dB) Power (W) Configuration Sample
1H 2.5 - 4 970 λ/2 Adamantane
31P 2.5 - 1.3 521 λ/2, range coil ADP
79Br 3 -0.77 460 λ/2 KBr
15N 5.5 - 3.12 792 λ/4 Glycine

Temperature test:
Probe tested at indicating temperature of 300 oC (real temperature 284 oC if calculated with a 0.025 ppm / oC slope for 79Br on KBr).
