9.  PRESSURE MEASUREMENT

Pressure value is determined using following equation  

Where:
I  - Current in amps.
V - Voltage in volts.
U - Pressure units conversion factor (1 for Torr, 1.33 for mBar and 133 for Pascal). 
F - Configured pump pressure factor. Typically set to 1. See “11.4 Supply Setup” on page 8.
S - Configured pump size in l/s. See “11.4 Supply Setup” on page 8.

10. FRONT PANEL

Figure 1.  MPCq Front Panel

10.1 Description

Front panel containts:
- Main power on/off rocker type switch (hard switch, when in off position main power is completely cut off from the unit)
- Main power indicator lamp (color green)
- 7” TFT WVGA (800x480) Color LCD, 16:9 aspect ratio, touchscreen capable (primary user interface)
- Two supply HV on/off indicator lamps (color red). Note, both lamps are installed even in single supply configuration.
