The ring heater was turned on today to check whether running the ring heater had an effect on the vacuum pressure.   15W of power was put through each segment of the ring heater at 19:07:30 UTC until 19:37:08 UTC (by adding an offset of 25,000 counts to H2TCSETMY _EMTY_RING_HTR_SEG1_DC_I_SET and H2TCSETMY_ETMY_RING_HTR_SEG2_DC_I_SET), which is close to the maximum ouput of the ring heater.  The vacuum in BSC6 was not affected by running the ring heater, which is good.

I added in gains to the ring heater input and readout channels so that the we can input the current in amps and readout the voltage and ring current on volts and amps instead of counts (reffering to D1002529 for  the required conversion factors).

• To channels H2TCSETMY _EMTY_RING_HTR_SEG1_DC_I_SET and H2TCSETMY _EMTY_RING_HTR_SEG2_DC_I_SET I added a gain of 3.9961e4 amps/count so that you can input the curent in amps and the output of the channel is in counts (using conversion factors 0.082A/V and 20^16/20 count/V)
• To channels H2TCSETMY _EMTY_RING_HTR_SEG1_I_MON and H2TCSETMY _EMTY_RING_HTR_SEG2_I_MON I added a gain of 4.982e-5 counts/amp so that the output of the channel is in amps (conversion factors are 40/2^16 V/count and 1/12.25 A/V)
• To channels H2TCSETMY _EMTY_RING_HTR_SEG1_V_MON, H2TCSETMY _EMTY_RING_HTR_SEG1_LV_MON, H2TCSETMY _EMTY_RING_HTR_SEG2_V_MON, H2TCSETMY _EMTY_RING_HTR_SEG2_LV_MON I added a gain of 0.0024 counts/volt so that the output is in volts (conversion factors are 40/2^16 V/count, 1/0.25 V/V).
