HV burnin

Step 1: Set Voltage to 50 volts on all channels. Probe HVB to be sure that all sense, field, and guard wires have a voltage. (You should set current threshold to 10 microAmps on the HV supply)

Step 2: While monitoring the current, ramp the HV at a speed of 5 V/s to the following

G:F:S= 525,-700,700

Step 3: Begin to take data recording the time and sense wire current as you ramp up the sense wire HV to 1400 volts while restricting the current draw to less than 10 micraAmps. Measure the voltage and current if either changes by more than 10%.
