1. Pressure Display. The default display is the pressure in the attached piece of equipment in units of mm of Hg
(torr). The set point pressure can be seen any time by holding in the “ * ” button.
2. Control Key. Pressing (and holding) this button causes the regulator to display the set point pressure as a
blinking number in the display. The set point pressure is entered by holding in the control key and
simultaneously pressing the “▲” button to increase or the “▼” button to decrease the displayed value.
3. Decreases
(▼) or increases (▲) the set point pressure when the “ * ” button is simultaneously held in.
4. Regulators Power Switch.
5. Indicates the position of the regulator selection switch (#6).
6. Regulator Selection Switch. A three position switch that determines the pressure in the attached equipment
(see Section 3.6). The different switch positions have the following effects:
Meter: Evacuates the attached equipment to the set point pressure entered in the controller.
Off: Isolates the vacuum pump from the attached equipment. In this position the equipment can
be opened to the atmosphere while the vacuum pump is running.
Full Vacuum: Opens the regulator continuously to the vacuum pump (independent of set point pressure).
The pressure in the attached equipment is lowered to the limit achievable by the vacuum
pump.
7. Optional serial port for remote PC control and data acquisition.
Warning:
J-KEM’s Model 200 Digital Vacuum Regulator should only be used with vacuums. It is not
designed to regulate pressures above atmospheric pressure. Exposure to pressures above atmospheric
pressure may result in damage to the regulator.
