• Reads vacuum in 7 international units
• Uses 

Ω the battery power than other models

• Cleaning port provides quick cleaning and drying of sensor
• Uses standard 9V Alkaline battery
• Convenient built-in hanger

• Turning the vacuum gauge ON: Press and hold the ON button 
  for about 3 seconds, until "POWER UP" appears on the display.
• Turning the vacuum gauge OFF: Press the OFF button
  To prolong battery life, when vacuum reading is above 12,000
  Microns for about 10 minutes, the unit will automatically turn OFF.
• Changing the scale: Press the Scale button to change the display
  to the next scale. The scale order is: Microns, PSI, Inches of 
  mercury (InHg), milliBars, Pascals, Torr and milliTorr. DVG64 will 
  keep the scale settings even if the power is turned OFF.

 

• When the vacuum reading is above 12,000 Microns (1,600 
  Pascals),  the first line of the display shows "Atm." The second 
  line displays a bar graph to indicate the direction in which the 
  vacuum is moving.  When the bar graph is moving from left to 
  right, the pressure is increasing. When the bar graph is moving 
  from right to left, the pressure is decreasing. The speed of the
  bar graph indicates how fast the pressure is increasing or 
  decreasing. The bar graph indicator may be inaccurate for a few 
  seconds after the evacuation of the system has begun.

• The bar graph disappears if the vacuum does not change for 
  about 10 seconds. When the vacuum reading is below 12,000
  Microns (1,600 Pascals), the vacuum in the selected units is  
 displayed.

The VG64 should only be connected to the vacuum system at  
the vacuum port. The "Auxiliary Port" is primarily for cleaning  
and should normally be closed with the supplied cap.

It is recommended that the sensor be cleaned periodically to 
maintain unit accuracy . Oil and other contaminants reduce the 
accuracy of the unit. Follow the instructions below for cleaning.

• Close the Vacuum port with the supplied cap.  
  Open the Auxiliary port. 
• Use an eyedropper to pour about 2 teaspoons of ordinary 
  rubbing alcohol into the Auxiliary port. 
• Close the Auxiliary port with the supplied cap. Both the 
  Vacuum and Auxiliary ports should now be closed.
• Shake the DVG64 unit for about 10 seconds. A slight 
  movement of the vacuum sensor in the case is normal and 
  does not affect the internal connection in any way.
• Open both the Vacuum and the Auxiliary ports.
  Empty the alcohol, and air dry the sensor.
• Close both the Vacuum and the Auxiliary ports with the 
  supplied caps when the DVG64 is not used. This prevents 
  contamination of the sensor.
