Pressing and releasing the Power button turns on the backlight. • Changing the scale: Press the UNITS button while in normal operation to change the display to the next scale. The scale order is: Micron, mTorr, Torr, Pascal, mBar. The VG640 will keep the scale settings even if the power is turned OFF. CLEANING THE VG640 VACUUM SENSOR It is recommended that the VG640 sensor be cleaned periodically to maintain unit accuracy. Oil and other contaminants reduce the accuracy of the VG640 unit. Follow the instructions below for cleaning. • Use an eyedropper to pour approximately 2 teaspoons of ordinary rubbing alcohol into the vacuum port. • Close the port with the supplied cap. • Shake the VG640 unit for approximately 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 the vacuum port. Empty the alcohol and air dry the sensor. Close the vacuum port with the supplied cap when the VG640 is not used. This prevents contamination of the sensor. 90% of the vacuum gauge warranty returns that SUPCO receives are due to contaminated sensors. For vacuum gauges that are heavily contaminated, leave the alcohol in the gauge overnight to clean the sensor more effectively. CHECKING HVAC SYSTEMS FOR LEAKS When checking a system for leaks use only copper tubing and a vacuum proof valve. Generally standard hoses will not hold a vacuum. If using the blank-off valve on the vacuum pump check it for leaks periodically. At the beginning of the test the VG640 reading may increase due to system equalization. The vacuum reading should hold after a minimum of 5 minutes. If the reading continues to increase it may indicate a leak in the system. SETTING THE ALARMS Press the SET button. The unit will display “Set Alarm Low” and show the current value of the low alarm. Use the up (UNITS) and down (MUTE) buttons to set the alarm from 0 to 19000 Microns. To turn the low alarms OFF, press the down button while the set low alarm is at 0 Microns, or press the up button while the set low alarm is at 19000 Microns. Press the SET button when you are done setting the low alarm,. The unit will now display “Set Alarm High” and show the current value of the high alarm. Use the up (UNITS) and down (MUTE) buttons to set the high alarm from the value of the low alarm to 19000 Microns. Note that the VG640 unit will not allow you to set the high alarm below the low alarm. To turn the high alarms OFF, press the down button while the set high alarm is at the low alarm value, or press the up button while the set high alarm is at 19000 Microns. Press the SET button when you are done setting the high alarm. The unit will return to normal operation. To see the current value of the low and high alarms, press the SET button. The unit will show the current value of the low alarm. Press the SET button again to display the current value of the high alarm. Press the SET button again to return the unit to normal operation. When the VG640 unit is turned OFF, the value of the low alarm is retained, but the value of the high alarm is always set to OFF.
