  • Page 5 Explosive Gases Do not use the Terranova® 907 to measure the pressure of combustible gas mixtures. Although the pressure gauge normally operates at low temperatures, it is possible that momentary transients or controller malfunction can raise the pressure gauge above the ignition temperature of combustible mixtures. This, in turn, can create an explosion which can damage equipment and / or injure personnel.

  • Page 6: Introduction

    Introduction The Terranova® 907 Dual Gauge Controller is designed to simultaneously operate both a Granville-Phillips 275 Convectron® gauge, MKS / HPS Series 317 convection-enhanced Pirani gauge, or equivalent pressure gauge and a capacitance diaphragm gauge such as the MKS 722B Baratron®...
  • Page 7 Connecting the Pressure Gauge The Terranova® 907 has a female 9-pin D-sub port located on the back of the control unit labeled SENSOR(S) to connect the pressure gauge cable (see Figure 2). A special hybrid cable is required to simultaneously connect both the convection-enhanced Pirani and capacitance diaphragm gauge to the control unit.

  • Page 8: Operation

    Operation Self-Test The Terranova® 907 will perform a self-test at power ON. The self-test cycle is initiated by a BEEP sound followed by: 1. All pressure unit LEDs become illuminated 2. All function indicator LEDs become illuminated 3. All numeric display indicators become illuminated 4.
  • Page 9 5. Press the SELECT button a fifth time to set or adjust the full-scale range of the capacitance diaphragm gauge. Use the RAISE or LOWER button to select the proper CDG RANGE value shown on the display. Default full-scale range is 1.00 Torr.

  • Page 10: Zero Adjustment

    Zero Adjustment Zero adjustment is recommended when installing a new pressure gauge or to restore pressure output accuracy. The Terranova® 907 can be either zero adjusted or set to a specific low- pressure value via the GAUGE ZERO value. Zero adjustment should be conducted before the atmospheric pressure adjustment.

  • Page 11: Upper Range Pressure Adjustment

    Upper Range Pressure Adjustment Convection-enhanced Pirani Gauge Atmospheric pressure adjustment is recommended when installing a new pressure gauge or to restore pressure output accuracy. The Terranova® 907 can be set to either local atmospheric pressure – 760 Torr (1013 mbar) at sea level – or a specific high-pressure value via the CALIB / CONV ATM pressure value.

  • Page 12: Changing Pressure Gauge Curves

    Changing Pressure Gauge Curves The Terranova® 907 is able to output pressure readings based on the pressure curve of either the Granville-Phillips 275 Convectron® gauge (i.e. 275) and equivalent sensors or the MKS / HPS Series 317 (i.e. CEP) sensor. The default pressure gauge curve is CEP. To change pressure gauge curves: 1.

  • Page 13: Restoring Default Values

    Restoring Default Values Restoring default parameters provides a starting point for control unit re-adjustment in the event pressure measurements become unreliable. To restore Terranova® 907 default parameters: 1. Remove power from the control unit 2. Simultaneously depress the RAISE and LOWER buttons while restoring power to the control unit 3.
