High Voltage Power Supply (HVPS)

The HVPS reading is a measure of the scaled-up HVPS programming voltage. The voltage used to set the HVPS output is generated on the Preamp board. Its value is between 0 and 1 volt, corresponding to a voltage of 0 to 1000 volts out of the HVPS. The HVPS front panel TEST measurement will be typically around 450-650 V.

DC Power Supply (DCPS)

The DCPS voltage is a composite of the 5 and ± 15 VDC voltages in the Power Supply Module. This is meant to be a quick indicator to show if the PSM is working correctly. The nominal value is 2500 mV ± 200 mV.

Reaction Cell Temperature

This is a measurement of the temperature of the reaction cell. It is controlled by the computer to 50 ± 1°C. Temperatures outside this range will cause the M100AH output to drift.

Box Temperature

This TEST function measures the temperature inside the chassis of the M100AH. The temperature sensor is located on the Status/Temp Board. Typically it runs 2 to 10°C higher than the ambient temperature. The M100AH has been engineered to operate over 5 to 40°C ambient temperature range.

PMT Temperature

The temperature of the PMT is closely controlled by a dedicated proportional temperature controller. The nominal set-point is 7 ± 1°C. Readings outside this range will cause instrument drift due to gain changes in the PMT detector.

Time

This is an output of the M100AH's internal time of day clock.
