All RHs running within specifications. Passed installation acceptance testing
The attached PDFs show the resistance measurements for all RHs and the relative resistance vs time for the RHs as 1W is applied to each segment. All segments are operating within nominal parameters.
The resistances for the segments are:
| Segment | Resistance (Ohms) |
| ITMX UPPER | 44.0 |
| ITMX LOWER | 42.4 |
| ITMY UPPER | 40.7 |
| ITMY LOWER | 42.5 |
| ETMX UPPER | 41.9 |
| ETMX LOWER | 41.0 |
| ETMY UPPER | 42.2 |
| ETMY LOWER | 43.6 |

Just for reference, here is the transient thermal lens in ITMX, as measured by the HWS, from this morning's 2W RH test (~1800s of applied power).

A follow-up. The data from the RTD temperature sensors for each RH is plotted in the attaced PDF.
The ETMY and ITMX RH RTDs are non-responsive.
