BATTERY
• BATTERY LIFE
To insure the best accuracy and performance be sure to have sufficient battery life. It is
recommended to have two bars or more.
• INSTALLATION
Slide to remove the battery compartment cover. Make sure to place the batteries into the
compartment with the correct polarity. Replace battery cover.
BASIC SET-UP
• POWER
Press the
button to turn the unit on. The vacuum gauge's display will count down during
warm-up, then the vacuum will be displayed. Above 20,000 microns, dashes will be displayed.
• UNITS
Press the units button once to enter unit mode. Use the UNITS button to scroll through the
units until desired selection is displayed. To save the selected units and return to sensing
vacuum, press the ENTER button.
• VACUUM LEVEL TARGET ALARM
The alarm indicates when the vacuum has dropped below a set value. Press ALARM once to
display the current setting. Use the and arrows to adjust the alarm setting. Press ENTER
to save the new setting. To acknowledge the alarm and silence it, press any button. To keep
the alarm from engaging, set the alarm to 0.
• BACKLIGHT
The backlight will turn on when the unit turns on. The backlight will automatically turn off
after 3 minutes. To turn the backlight back on, press any key.
• AUTO OFF
The vacuum gauge will turn off after 10 minutes at atmospheric pressure. The vacuum gauge
will not turn off at deep vacuum or if Bluetooth® is connected.
CALIBRATION
NOTE: The vacuum gauge comes calibrated from Mastercool. We recommend doing an
atmospheric calibration before each use.
• Make sure the vacuum gauge is at a constant temperature for 15 minutes or longer before
calibration.
• The vacuum gauge uses two-point calibration for greater accuracy. The two points are
atmospheric pressure and a deep vacuum of less than 100 microns.
• To exit the calibration without changing the existing calibration, turn the vacuum gauge off.
