 The extent of the trim range can be determined by probing the location shown in <imgref trimpots2> with a voltmeter referenced to case ground (the outer shell of the SMA connector is a good reference point). Probing this location gives the wiper voltage of the trimpot which corresponds to temperature as shown in the table below. This 10-turn trim pot sets temperature from 15°C (fully CCW) to 75°C (10 turns CW).  The 5-turn point is approximately 42°C. The following table gives approximate temperature settings for the three available alkali options: The extent of the trim range can be determined by probing the location shown in <imgref trimpots2> with a voltmeter referenced to case ground (the outer shell of the SMA connector is a good reference point).
