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 PREVIOUS until the Main Menu appears), Menu [F6 ⎢Setup [F2] ⎢User [F2].

2.Turn the rotary knob until the label “Display digits” is highlighted.

3.Turn the rotary knob further until the desired number of digits from the default resolution is highlighted (-1, 0, +1), and then press the ENTER key to select.

Key Click

The Calibrator can be configured to emit a “clicking” sound each time a key is pressed.

1.The key “click” is set from the Menu Setup User. From the Main Menu (press PREVIOUS until the Main Menu appears), press Menu [F6 ⎢Setup [F2] ⎢User [F2].

2.Turn the rotary knob to highlight “Key click” and then highlight either On or Off.

3.Press the ENTER key to select.

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.

mTorr = kPa x	1000 mTorr	x	1 Torr	x	1 mmHg 0°C	x	0.1450377 psi
	1 Torr		1 mmHg 0°C		0.0193377 psi		1 kPa

thus the conversion factor simplifies to mTorr = kPa x 7500.6180
