Pressure Filter
The Pressure Filter is used to adjust the degree to which the front display pressure value
is filtered. A value of four (4), is the default value. As the value increases, the filtering
level increases, however, the display update rate reduces. Typical filter values would
range between 1 to 10.
Changing the Number of Decimals
Each unit has a default number of decimal places used for pressure display. This may be
adjusted up or down by one decimal place.
1. The decimal digits are set from the Menu | Setup | User. From the Main Menu (press

Menu | Setup — Units
In addition to the standard units of measure provided by the Calibrator, four user-defined
units are available. To create a user-defined unit, the user enters a name that is one to ten
characters long and a conversion factor that is a multiple of kiloPascals (kPa).
For example, using the information from Table 2-1, the conversion factor for millitorr or
one micron of mercury at 0 ° C is calculated as follows.
