 ==== High Voltage Test (SB¹) ====
-The HV command invokes a test used to determine the optimum high voltage setting for the photomultiplier. Once the instrument is properly setup (see Appendix F - jumper J2 on the high voltage module must be moved from Pins 2-3 to Pins 1-2 after the Brewer power is turned off, then the power returned to perform the test.  After the test is performed the brewer power must again be turned off and the jumper J2 on the high voltage module must be returned from Pins 1-2 back to Pins 2-3, and then the power restored for normal operation).  The HV command starts an automatic high voltage test and writes the results to HVJJJYY.III.\\
