FEATURES
• 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
OPERATING CONTROLS
• 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.
UNDERSTANDING THE DISPLAY
• 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.
CONNECTING TO THE VACUUM SYSTEM
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.
CLEANING THE VACUUM SENSOR
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.
