The Field Analysis Vacuum Meter has four display modes: one numeric, and three graphical. The numeric display has three numeric formats: Low Resolution, High Resolution, and Scientific Notation. Display modes are selected from the settings menu “Display”, and numeric formats are selected from the Setting option “display”. The SEL button enters and traverses the Settings menu. Display Large number Numeric display with the “High Resolution” format Large number display with the “scientific” format The numeric display shows the currently configured units, in these examples the vacuum pressure units...

The battery indicator shown at full strength Vacuum Range Indicator In practice, this indicator changes based on the current level of pressure. 11.88 * i The numeric display shows when the vacuum sensor tube is disconnected, failed or when an over-range condition exists (pressure above 1000 Torr).

Display Bar Graph The bar graph visualizes the current sensor reading with a 6-stage stepped bar. Display Pump-down graph The pump-down graph plots time horizontally and logs pressure vertically. The horizontal time scale is selected using the configuration option “Pump-down time”. The vertical pressure scale is logarithmic, indicating order of magnitude from one micron to atmosphere. The top left is the current vacuum pressure display figure. In the center of the first line is the Vacuum System Analysis, “PUMP”, and to the right is one of either the pump down rate in units per minute, or the...

Display Line graph The auto-scaling (or, auto-ranging) time graph is a microscope into the pump down data. Current or most recent pressure Maximum & Minimum value in measured range In this mode, the pump down graph is shown with a linear pressure scale that is fit to the pressure range of the data set. The height of the graph display is the pressure range of the data set in a linear scale (not log). The top left figure is the maximum value in this range, and the bottom left figure is the minimum value in this range. The top right figure is the current or most recent value in the instrument. Please...

Display Pressing the SEL button from the vacuum display screen will present three submenus: Settings, Calibration and Set-points. The settings menu is a linear series of menu options that are stepped or skipped through using the SEL button. Above each button is a utility hint to indicate specific button function. The SKIP hint is above the SEL button to indicate that the SEL button is used to step or skip to the next menu screen with no configuration change. The ENTER hint above the ENT button indicates that this button is used to enter the display mode as shown in the menu screen. Using the...

High Resolution The High Resolution format has three digits of precision. For example, an internal vacuum value of 1234 microns (µm Hg) would be displayed as 1.23 torr in the High Resolution format with torr units. Additionally, this format gives the raw vacuum measurement data which may be useful for trending, but could also result in a noisier reading. Low Resolution The Low Resolution format has two digits of precision. For example, an internal vacuum value of 1234 microns (µm Hg) would be displayed as 1.2 torr in the Low Resolution numeric format with torr units. This number format also gives...

Pumpdown time The pump-down time configuration option defines the width of the Pumpdown Graph and pumpdown rate window. The pumpdown rate is the difference between the start and end of the pressure data shown in the pumpdown graph. For example using a pump down time of ten minutes, a system pump down from atmospheric pressure to one torr in ten minutes has a pump down rate of 760 torr per ten minutes or 76 torr per minute. Auto Off time Use this setting to save battery power during periods of inactivity. The figure zero will disable the auto off battery saver feature. To see the specifics of...
